Description

Folding screen display application method and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of electronics, in particular to a method for displaying applications on a folding screen and electronic equipment.

Background

Currently, when a user operates an application on an electronic device, some waiting scenes exist in the application. For example, the process of matching the companions in a mobile game requires the user to wait for a certain time before joining the game team. For another example, a video application installed in a mobile phone may play an advertisement for a certain period of time before the video application plays a video, and the video application needs to start playing the video after the advertisement is played.

For some users, these waiting times are too long, which may result in the user wanting to switch to another application, and when the user switches back to the application again after switching to another application, it may be found that a wait again is necessary. For example, if the user switches the mobile phone application in the waiting scene of the game application, the game application will be suspended directly, and when the game application is switched to the foreground, the user needs to continue waiting from a previously cut-out time point or needs to reconnect with the server, which results in low time utilization rate of the user in the waiting scene and poor user experience.

Disclosure of Invention

When the electronic equipment is respectively in the unfolding state and the folding state, different application interfaces are displayed so as to meet the operation habits of users under different screen sizes. In addition, when the electronic equipment is changed from the unfolding state to the folding state, the running state of the first application in the background is consistent with the running state of the foreground, so that the electronic equipment is in the unfolding state after being unfolded, the first interface is displayed, for example, the first interface is a waiting scene, a user can display the second application through the folding electronic equipment, the time utilization rate of the user in the application waiting scene is improved, and better experience is brought to the user.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

Taking an example that an Android system is installed on the electronic device, when the electronic device runs an application program, the electronic device system keeps an application process as long as possible. In the using process of the electronic equipment, when an application is quitted by a user and is not immediately checked and killed by the system, but when the memory of the Android system is insufficient, in order to establish a new process, or run a more important process for the system, or ensure the fluency of the system, the system can kill some processes according to the priority to recycle the memory. The Android system may determine which process to kill according to the relative importance degree of the processes of the different application programs to the user, or the Android system may determine which process to kill according to an application white list in the electronic device. Background keep-alive means that a process can run all the time in the background and keep in an undamaged state. For example: when the WeChat application runs in the background, the WeChat application can still receive messages sent by other electronic equipment, namely when the WeChat application runs in the background, if the system memory is insufficient, other processes kill in the WeChat application can be kept alive only, and the processes receiving the messages are kept alive. It can be understood that the method for keeping the process alive is that the system does not kill the process, that is, the system notifies the service program performing killing operation to skip the target process. Therefore, when an application runs in the background, the application is kept alive in the background, and the state of the application running in the background is not consistent with the state of the application running in the foreground, but certain processes of the application are guaranteed not to be killed by the system.

In a specific application, when the application run by the electronic device is a video application, in the process of playing the video, if it is detected that the user exits from the operation of the video application, the video application is switched to be run in the background by the electronic device. When the user switches back to the video application again, the electronic device cannot directly display the video interrupted by the last playing of the video application, but displays an interface of the video application. This approach does not guarantee that the application continues to run in the background. Particularly, when a current scene in one application is a waiting scene, such as advertisement playing time, leader video playing time or trailer video playing time in a video application, or a scene in which a player is waiting to join in a game application, and the like, in the waiting scene, a user can switch to other applications in the electronic device, and when the user switches back to the application again, the user still needs to continue waiting in the waiting scene, and background keep-alive can only ensure that the application is not killed, and cannot ensure that the application continues to run in the background.

For the electronic equipment comprising the folding screen, the application switching mode is similar to the electronic equipment with the non-folding screen, and the application switching mode cannot exert the characteristics of the electronic equipment with the folding screen. And the existing background keep-alive mode cannot really ensure that the application continues to run in the background. When a user uses an electronic device including a folding screen, the time utilization rate of the user in a waiting scene of an application should be improved, and a better experience is provided for the user.

Therefore, the application method of the folding screen display provided by the embodiment of the application can be applied to the electronic equipment comprising the folding screen, and in the using process of the electronic equipment, when the electronic equipment is in the unfolding state and the folding state, the electronic equipment displays different application interfaces. When the electronic equipment is in the unfolding state, the folding screen displays the interface of the first application. When the electronic device is converted from the unfolded state to the folded state, the electronic device displays the interface or the main interface of the second application, and the electronic device can continue to run the first application in the background. And the state of the first application running in the background is consistent with the state of the first application running in the foreground. When the electronic equipment is converted from the folded state to the unfolded state, the electronic equipment displays the display interface of the first application again. When the application runs in a background keep-alive mode, the running state of the application can be really guaranteed to be consistent with the running state of the foreground, and user experience is improved.

The electronic device including the folding screen in the embodiment of the application can be divided into two types: the electronic device with the foldable screen turned outwards is the one, and the electronic device with the foldable screen turned inwards is the other. The electronic device may be foldable such that the folded screen forms a plurality of display areas, e.g., the electronic device may be foldable along a fold screen edge or fold axis to form a first screen and a second screen.

For example, fig. 1 is a schematic product form of an electronic device folded outward according to an embodiment of the present application, and fig. 1 (a) is a schematic form of the electronic device 100 folded outward when fully unfolded. The electronic device 100 may be folded along the folding edge in the direction shown in fig. 1 (a) to form the first screen and the second screen shown in fig. 1 (b), the electronic device 100 may be further folded along the folding edge to form the form schematic diagram of the electronic device 100 shown in fig. 1 (c) after being completely folded, and the first screen and the second screen are opposite to each other after being completely folded by the electronic device 100. When the electronic device is in a folded state, the first screen or the second screen can be displayed as a main screen.

It is understood that when the electronic device is in the folded state, the interface may be displayed on the first screen or the second screen; when the electronic device is in the unfolded state, the interface can be displayed on the first screen and the second screen. The description of the unfolded state and the folded state of the electronic device may refer to the description of the following embodiments, which are not described herein.

For another example, please refer to fig. 2, which is a schematic product form diagram of an inward-folded electronic device 100 according to an embodiment of the present application. Fig. 2 (a) is a schematic view of the electronic device 100 folded inward in a fully unfolded state. The electronic apparatus 100 may be folded along the folded edge in the direction shown in fig. 2 (a) to form the first screen and the second screen shown in fig. 2 (b). The electronic device 100 continues to be folded along the folding edge, and the completely folded electronic device 100 shown in fig. 2 (c) can be formed. The electronic device 100 is fully folded with the first screen and the second screen opposite, both of which are not visible to the user. A line 201 shown in (c) of fig. 2 indicates a plane where the first screen and the second screen are in contact. In addition, the inwardly turned electronic device may further include a third screen. The third screen is arranged on the back of the first screen or the second screen. It will be appreciated that for an inwardly folded electronic device, the third screen is visible to the user in both the folded and unfolded states. When the electronic equipment is in a folded state, the interface is displayed on the third screen, and when the electronic equipment is in an unfolded state, the interface can be displayed on the first screen and the second screen.

It is worth mentioning that, for the electronic device turned outwards, when the electronic device is in the folded state, the first screen or the second screen may be used as the main screen. For the electronic equipment turned inwards, when the electronic equipment is in a folded state, the first screen and the second screen are invisible to a user, and the third screen is used as a main screen.

Generally, the included angle α between the first screen and the second screen of the electronic device including the foldable screen (including the electronic device folded outward and the electronic device folded inward) is in a range of [0 °, 180 ° ]. In the embodiment of the application, if alpha is [0 DEG, P ], the electronic equipment can be determined to be in a folded state; if α ∈ (P, 180 ° ], the electronic device may be determined to be in the unfolded state, or, if α ∈ [0 °, P), the electronic device may be determined to be in the folded state; if α ∈ [ P, 180 ° ], it can be determined that the electronic device is in the unfolded state. Where P is a preset angle threshold. P may be determined according to the usage habit of a large number of users using the folding screen; alternatively, P may be set in the electronic device by the user.

In some embodiments, when the angle α between the first screen and the second screen is greater than 90 °, the probability that the user wants to use the first screen and the second screen as a whole (i.e., as a complete display screen) is high according to the usage habit of most users. Therefore, the preset angle threshold P in the embodiment of the present application may be greater than 90 °. The value range of the preset angle threshold P may be (90 °, 180 °). For example, the preset angle threshold P may be 100 °, 120 °, 135 °, 140 °, 145 °, 150 °, or the like.

It should be noted that, at least two screens formed by folding the electronic device (including the electronic device turned inward and the electronic device turned outward) in the embodiment of the present application may be multiple screens that exist independently, or may be a complete screen of an integrated structure, and only is folded to form at least two parts.

For example, the folded screen may be a flexible folded screen. The flexible folding screen comprises a folding edge made of flexible materials. Part or all of the flexible folding screen is made of flexible materials. At least two screens formed by folding the flexible folding screen are a whole screen of an integral structure, and only the flexible folding screen is folded to form at least two parts.

For another example, the foldable screen of the electronic device may be a multi-screen foldable screen. The multi-screen folding screen may include a plurality (two or more) of screens. The plurality of screens are a plurality of individual display screens. The plurality of screens may be connected in turn by a folding shaft. Each screen can rotate around a folding shaft connected with the screen, and folding of the multi-screen folding screen is achieved.

In fig. 1 and fig. 2, the foldable screen in the embodiment of the present application is described by taking the foldable screen as an example. In addition, in the following embodiments of the present application, the method provided in the embodiments of the present application is also described by taking the foldable screen as a flexible foldable screen as an example.

The ISP is used to process the data fed back by the camera 193. For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on the noise, brightness and skin color of the image.

In the embodiment of the application, the NPU may identify the first interface of the first application through a picture identification algorithm, and determine a countdown duration of a countdown icon in the first interface of the first application.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to extend the memory capability of the electronic device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music, video, etc. are saved in an external memory card.

The internal memory 121 may be used to store computer-executable program code, which includes instructions. The processor 110 executes various functional applications of the electronic device 100 and data processing by executing instructions stored in the internal memory 121.

The pressure sensor 180A may be a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, or the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. In the embodiment of the present application, the electronic device 100 may collect, by the pressure sensor 180A, a pressing force (or referred to as a pressing pressure) of a touch operation input by a user on the touch screen (i.e., the display screen 194).

The gyro sensor 180B may be used to determine the motion attitude of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., the x, y, and z axes) may be determined by gyroscope sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 through a reverse movement, thereby achieving anti-shake. The gyroscope sensor 180B may also be used for navigation, somatosensory gaming scenes. In the embodiment of the present application, the foldable screen of the electronic device 100 may be folded to form a plurality of screens. A gyro sensor 180B may be included in each screen for measuring the orientation (i.e., the directional vector of the orientation) of the corresponding screen. The electronic device 100 may determine the included angle between adjacent screens according to the measured angle change of the orientation of each screen.

It should be noted that, in the embodiment of the present application, the electronic device includes a foldable screen, and the foldable screen is divided into a plurality of display areas after the electronic device is folded, where each display area is referred to as a screen. A gyro sensor 180B may be included on each screen to measure the orientation (i.e., the directional vector of the orientation) of the corresponding screen. For example, as shown in fig. 1 (B), the electronic device is folded to form a first screen and a second screen, and the first screen and the second screen are both provided with a gyroscope sensor 180B therein, so that the orientations of the first screen and the second screen can be measured respectively. And the electronic equipment determines the included angle between the first screen and the second screen according to the measured orientation angle change of each screen.

For example, the electronic apparatus 100 is folded to form a first screen (illustrated as a screen) and a second screen (illustrated as B screen) illustrated in fig. 4A, the a screen is provided with the gyro sensor a, and the B screen is provided with the gyro sensor B. Here, the present embodiment describes a principle that the gyro sensor a measures the orientation of the a screen (i.e., the directional vector of the orientation), the gyro sensor B measures the orientation of the B screen (i.e., the directional vector of the orientation), and a principle that the electronic apparatus 100 calculates the angle α between the a screen and the B screen based on the orientation of the a screen and the orientation of the B screen.

Wherein the coordinate system of the gyro sensor is a geographical coordinate system. As shown in fig. 4B, the origin O of the geographic coordinate system is located at the point where the vehicle (i.e., the device containing the gyro sensor, such as the electronic device 100) is located, the x-axis points east (E) along the local latitudes, the y-axis points north (N) along the local meridian, and the z-axis points upward along the local geographic vertical line, and forms a right-hand orthogonal coordinate system with the x-axis and the y-axis. The plane formed by the x axis and the y axis is the local horizontal plane, and the plane formed by the y axis and the z axis is the local meridian plane. Thus, it can be understood that the coordinate system of the gyro sensor is: the gyroscope sensor is used as an origin O, the east direction along the local latitude line is used as an x axis, the north direction along the local meridian line is used as a y axis, and the upward direction along the local geographical vertical line (namely the opposite direction of the geographical vertical line) is used as a z axis.

The electronic apparatus 100 can measure the direction vector of the orientation of each screen in the coordinate system of the gyro sensor provided therein, using the gyro sensor 180B provided in each screen. For example, referring to the side view of the electronic device as shown in fig. 4A, the directional vector of the orientation of the a-screen measured by the electronic device in the coordinate system of gyro sensor a is vector z1, and the directional vector of the orientation of the B-screen in the coordinate system of gyro sensor B is vector z 2. The electronic device 100 utilizes equation (1):

the angle θ between vector z1 and vector z2 can be calculated.

As can be seen from fig. 4A, since the vector z1 is perpendicular to the a screen and the vector z2 is perpendicular to the B screen, the angle α between the a screen and the B screen can be obtained as 180 ° - θ. That is, the electronic device can determine the angle α between the a screen and the B screen according to the measured direction vector of the a screen in the coordinate system of the gyro sensor a (i.e., vector z1) and the direction vector of the B screen in the coordinate system of the gyro sensor B (i.e., vector z 2).

It should be noted that although the positions of the gyro sensors disposed in the a-screen and the B-screen do not overlap, that is, the origins of the coordinate systems of the gyro sensors disposed in the a-screen and the B-plane do not overlap, the x-axis, the y-axis, and the z-axis of the two coordinate systems are parallel, so that the coordinate systems of the gyro sensors disposed in the a-screen and the B-screen can be considered to be parallel. Thus, although the vector z1 and the vector z2 are not in the same coordinate system, the angle θ between the vector z1 and the vector z2 can be calculated by the above equation (1) because the axes of the two coordinate systems are parallel.

In some embodiments, the angle α between the a screen and the B screen can also be measured by one or more other sensors. For example, one acceleration sensor 180E may be provided in each of the folding screens. The electronic device 100 (e.g., the processor 110) may measure the motion acceleration of each screen as it is rotated using the acceleration sensor; and then calculating the rotation angle of one screen relative to the other screen according to the measured motion acceleration, namely the included angle alpha between the screen A and the screen B.

In other embodiments, the gyro sensor 180B may be a virtual gyro sensor formed by combining other sensors. The virtual gyroscope sensor can be used for calculating the included angle between adjacent screens of the folding screen, namely the included angle alpha between the screen A and the screen B.

The magnetic sensor 180D includes a hall sensor. The electronic device 100 may detect the opening and closing of the flip holster using the magnetic sensor 180D.

The acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically three axes). The magnitude and direction of gravity can be detected when the electronic device 100 is stationary. The method can also be used for recognizing the posture of the electronic equipment, and is applied to horizontal and vertical screen switching, pedometers and other applications.

The proximity light sensor 180G may include, for example, a Light Emitting Diode (LED) and a light detector, such as a photodiode. The light emitting diode may be an infrared light emitting diode. The electronic device 100 emits infrared light to the outside through the light emitting diode. The electronic device 100 detects infrared reflected light from nearby objects using a photodiode. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100.

The ambient light sensor 180L is used to sense the ambient light level. Electronic device 100 may adaptively adjust the brightness of display screen 194 based on the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust the white balance when taking a picture. The ambient light sensor 180L may also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

The fingerprint sensor 180H is used to collect a fingerprint. The electronic device 100 can utilize the collected fingerprint characteristics to unlock the fingerprint, access the application lock, photograph the fingerprint, answer an incoming call with the fingerprint, and so on.

The temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 implements a temperature processing strategy using the temperature detected by temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device 100 heats the battery 142 when the temperature is below another threshold to avoid the low temperature causing the electronic device 100 to shut down abnormally. In other embodiments, when the temperature is lower than a further threshold, the electronic device 100 performs boosting on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on a surface of the electronic device 100, different from the position of the display screen 194.

In this embodiment, the electronic device 100 may detect a touch operation input by a user on the touch screen through the touch sensor 180K, and acquire one or more items of a touch position, a touch area, a touch direction, and a touch time of the touch operation on the touch screen. In some embodiments, the electronic device 100 may determine the touch position of the touch operation on the touch screen by combining the touch sensor 180K and the pressure sensor 180A.

The motor 191 may generate a vibration cue. The motor 191 may be used for incoming call vibration cues, as well as for touch vibration feedback. For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also respond to different vibration feedback effects for touch operations applied to different areas of the display screen 194. Different application scenes (such as time reminding, receiving information, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

Indicator 192 may be an indicator light that may be used to indicate a state of charge, a change in charge, or a message, missed call, notification, etc.

The SIM card can be brought into and out of contact with the electronic apparatus 100 by being inserted into the SIM card interface 195 or being pulled out of the SIM card interface 195. The electronic device 100 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 195 may support a Nano SIM card, a Micro SIM card, a SIM card, etc.

The methods in the following embodiments may be implemented in the electronic device 100 having the above-described hardware structure.

The software system of the electronic device 100 may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes an Android system with a layered architecture as an example, and exemplarily illustrates a software structure of the electronic device 100.

Fig. 5 is a block diagram of a software structure of the electronic device 100 according to an embodiment of the present disclosure. The layered architecture can divide the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into three layers, which are an application layer (referred to as an application layer), an application framework layer (referred to as a framework layer), and a kernel layer (also referred to as a driver layer) from top to bottom.

Wherein the application layer may comprise a series of application packages. As shown in fig. 5, the application layer may include a plurality of application packages such as application 1 and application 2. For example, the application package may be a camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, and desktop Launcher (Launcher) application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. As shown in fig. 5, the framework layer may include a Window Manager (WMS), an Activity Manager (AMS), a content provider and view system, and the like. Optionally, the framework layer may further include a telephony manager, a resource manager, a notification manager, etc. (not shown in the drawings).

Among them, the window manager WMS is used to manage the window program. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The Activity manager AMS is used for managing Activity and is used for starting, switching and scheduling each component in the system, managing and scheduling application programs and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The view system may retrieve a stored data file through a content provider when constructing an interface (e.g., a desktop including application icons) and display the interface according to the retrieved data file. In some embodiments, modifications may also be made to the data files stored in the content provider when the interface is built.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver. The kernel layer is a layer between hardware and software. The kernel layer may contain display drivers, input/output device drivers (e.g., keyboard, touch screen, headphones, speakers, microphones, etc.), camera drivers, audio drivers, and sensor drivers, among others.

The kernel layer may generate a responsive input event (e.g., a folding screen unfolding event) according to the input operation and report the event to the application framework layer. Interface display (including a display mode of a main interface, a window display mode and the like) is set by an activity management server AMS of an application framework layer. And the window management server WMS of the application framework layer draws an interface according to the setting of the AMS, then sends the interface data to the display driver of the kernel layer, and the display driver displays the corresponding interface on the folding screen.

The display scheme provided by the embodiment of the application is realized based on a free window (freeform) characteristic of google and a multi-window multi-task infrastructure. The display process provided by the embodiment of the present application can be seen in fig. 5. As shown in fig. 5, in an embodiment of the present application, the Activity manager AMS may include an Activity native management module and an Activity extension module. The Activity native management module is used for managing Activity, and is responsible for starting, switching and scheduling each component in the system, managing and scheduling application programs and the like. The Activity expansion module is used for setting a display mode, a window display mode and the like of the main interface according to the folding state or the unfolding state of the folding screen.

It is understood that, during the process of displaying the interface on the electronic device 100, the foldable screen of the electronic device 100 may be switched from the folded state to the unfolded state or from the unfolded state to the folded state. At this time, the folding driver (i.e., input/output device driver) of the driver layer may detect the folding event input by the user. In the embodiment of the present application, the folding event may be triggered by the operation of the user controlling the folding screen to be converted from the folding state to the unfolding state, and is referred to as a folding event 1. Alternatively, the folding event may be triggered by a user controlling the operation of the folding screen from the unfolded state to the folded state, and is referred to as a folding event 2. The collapse driver may report the collapse event to a window manager WMS of the framework layer (i.e., the application framework layer).

The window manager WMS may listen to a collapse event, and may determine to switch a display size after listening to the collapse event. The window manager WMS transmits a display change event to the activity manager AMS, and the activity manager AMS sets the window mode and the attributes of the window. When monitoring the folding event 1, the window manager WMS may determine that the display becomes large, and send a display change event 1 to the activity manager AMS. The display change event 1 is used for triggering the activity manager AMS to switch the window mode from the full-screen mode to the multi-window mode or the single-window mode, and to adjust the attributes of the window. The view system acquires data in the content provider, determines a displayed application interface, and the activity manager acquires the display interface in the view system and displays the interface of the first application. When the window manager WMS listens to the collapse event 2, it may be determined that the display becomes small, and the display change event 2 is transmitted to the activity manager AMS. The display change event 2 is used to trigger the activity manager AMS to switch the window mode from the multi-window mode or the single-window mode to the full-screen mode, and to adjust the attributes of the window. The view system acquires data in the content provider, determines a displayed application interface, and the activity manager acquires the display interface in the view system and displays an interface of a second application.

Illustratively, if the first application is a game application, the electronic device is in an unfolded state, and the display interface of the first application is displayed on the folding screen. As shown in fig. 6 (a), when the first application is a game application, the interfaces of the game friends are matched. The electronic device is converted from the unfolded state to the folded state, and the electronic device displays an interface of the second application. As shown in fig. 6 (b), the display interface of which the first application is "WeChat". After a preset time, for example, 20 seconds, the electronic device is changed from the folded state to the unfolded state, and the electronic device displays the interface of the first application. As shown in fig. 6 (c), the electronic device is converted from the folded state to the unfolded state, and the electronic device displays the display interface of the first application.

For example, the electronic device is in an unfolded state and the folding screen displays an interface of a first application. In response to the display change event 2, the activity manager AMS may request the window manager WMS to draw a window and call a display driver display interface: the electronic equipment is in a folded state, the folding screen is divided into a plurality of display areas, and the interface or the main interface of the second application is displayed on the main screen of the electronic equipment in the folded state. In response to the display change event 1, the activity manager AMS may request the window manager WMS to draw a window and call a display driver display interface to: the folding screen of the electronic equipment is in an unfolding state, and an interface of the first application is displayed on the folding screen.

The following description will be made on a folding screen display application method in the present application, taking an electronic device as a mobile phone, and taking the mobile phone as an outward-folded mobile phone as an example. When the mobile phone which is turned outwards is in a folded state, the first screen or the second screen can be used as a main screen. The flow of the method is shown in fig. 7, and includes steps 701-703:

step 701: when the mobile phone is in the unfolding state, a first interface is displayed on the folding screen.

The first interface is a display interface of the first application. Illustratively, the first application may be any application program in the cell phone. For example, the first application may be a video application, a gaming application, a text messaging application, or an instant messaging application (e.g., WeChat), among others. When the first application is operated in the foreground, the mobile phone can be a display interface of the first application.

Step 702: and responding to the mobile phone converted from the unfolding state to the folding state, displaying a second interface on a main screen of the mobile phone, and continuously running the first application on the background by the mobile phone.

And the second interface is a display interface of the second application or a main interface of the mobile phone. The main interface of the mobile phone can comprise a plurality of application icons.

For example, the second application may be an application that the handset runs in the background; or the second application is any application of which the running times or running duration of the mobile phone in the preset time is greater than a preset threshold; or the second application is a pre-configured application in the mobile phone.

For example, in a preset time, the mobile phone counts the number of times each application is run or the running duration of each application, and if the number of times each application is run in the mobile phone application, which is "wechat", "microblog", and "QQ", exceeds a preset threshold, the mobile phone may select any one of the applications as the second application.

It should be noted that, in the embodiment of the present application, when the mobile phone runs the first application in the background, the running state of the first application in the background is consistent with the running state of the first application in the foreground.

The embodiment of the present application describes a specific method in which, in response to the mobile phone being converted from the unfolded state to the folded state, the mobile phone continues to run the first application in the background.

For example, if the first interface in the first application matches a scene for a game player when the mobile phone is in the expanded state, as shown in (a) in fig. 6, the scene matches a scene for another game player for the mobile phone user in the game application, where a countdown 601 is set in the scene, and when the mobile phone is changed from the expanded state to the collapsed state, the countdown duration of the first application is not suspended but may continue to count down as it is in the foreground state when the first application is in the background operation. For example, when the mobile phone is in the extended state, the remaining waiting time of the countdown of the first application is 20 seconds. And in response to the mobile phone being changed from the unfolded state to the folded state, the first application is switched to the background to continue running, and the main screen of the mobile phone displays the interface of the second application. And after the second application runs for 10 seconds in the foreground, the mobile phone is changed from the folded state to the unfolded state, the mobile phone displays the first application, and the remaining waiting time of countdown of the first application is 10 seconds. That is, when the first application runs in the background, the remaining wait period in the countdown icon of the first application does not stop, but can continue to count down in the background.

It should be noted that the Activity lifecycle in the Android system may include: 1) when the Activity is started, the system calls the onCreate method, then calls the onStart method, and finally calls the onResume, and the Activity enters a running state. 2) When the current Activity is overlaid or locked by other activities, the system calls the onPause method to pause the execution of the current Activity. 3) When the current Activity returns to the foreground from the covered state or the screen is unlocked, the system calls the onResume method and enters the running state again. 4) When the current Activity is transferred to a new Activity interface or a Home key is pressed to return to the main screen, and the system exits from the background, the system calls the onPause method firstly and then calls the onsop method to enter a stagnation state. 5) When the user falls back to the Activity, the system calls the onRestart method, then calls the onStart method, and finally calls the onResume method to enter the running state again. 6) The current Activity is in a covered state or a background invisible state, namely 2) and 4), the system memory is insufficient, the current Activity is killed, and then when the user returns the current Activity, the onCreate method, the onStart method and the onResume method are called again to enter a running state. 7) When the user exits the current Activity, the system calls the onPause method, then calls the onsop method, and finally calls the onDestore method to finish the current Activity.

According to the lifecycle of Activity in the Android system, when the mobile phone runs the first application on the foreground, the mobile phone responds to the situation that the mobile phone is changed from the unfolded state to the folded state, the mobile phone displays an interface of the second application on the main screen, the mobile phone switches the first application to the background to run, and the first application belongs to 4 of the lifecycle), the system calls an onPause () interface, and after the system calls the onPause () interface, the first application is suspended. Namely, when the mobile phone runs the second application in the foreground, the first application is suspended in the background. It will be appreciated that when the first application pauses in the background, the remaining wait period in the countdown icon for the first application will also pause without continuing to count down in the background.

Therefore, in the embodiment of the present application, the mobile phone continues to run the first application in the background according to the foreground running state, specifically: and when the mobile phone runs the first application in the background, continuously counting down the waiting time in the waiting information in the first interface.

The mobile phone can continue to run the first application in the background according to the foreground running state through the following two implementation modes.

Implementation (1): in response to the handset transitioning from the unfolded state to the folded state, the handset intercepts a PAUSE command transmitted to the first application.

When the first application runs in the background, the mobile phone intercepts a PAUSE command transmitted to the first application, so that the running state of the first application in the background is consistent with the running state of the first application in the foreground. For example, the handset does not call the onPause () interface. That is, when the first application runs in the background, the system does not call the onPause () interface, and the first application will not receive the PAUSE command sent by the system, so that the first application can continue to run in the background, the remaining waiting time of the first application will not be suspended, and the countdown can continue in the background.

Implementation (2): when the first application runs in the background, the mobile phone transmits a second instruction to the first application, and the second instruction is used for indicating the first application to continue running according to the running state of the foreground.

For example, when the first application runs in the background, the mobile phone may call the onPause () interface, and transmit the second instruction through the onPause () interface, to instruct the first application to continue to run according to the state of the foreground running. For example, when the first application runs in the background, the mobile phone may call the onPause () interface and transmit the second instruction through the onPause () interface, and at this time, the first application may continue to run in the background as it is in the foreground running state. For example, the remaining wait period for the first application may continue to count down in the background as it would in the foreground. In this implementation, when the mobile phone transmits the continue operation instruction through the onPause () interface, the operation logic of the first application needs to be modified.

Step 703: and responding to the mobile phone converted from the folding state to the unfolding state, and displaying a first interface by the mobile phone.

It can be understood that when the mobile phone is changed from the unfolded state to the folded state, the first application continues to run in the background, and the main screen of the mobile phone displays the second application. After the second application runs for the preset time, the mobile phone is changed from the folded state to the unfolded state, the mobile phone displays a first interface, the first application also runs for the preset time in the background, and the first interface is the display interface after the first application continues to run for the preset time in the background. As shown in fig. 6, (a) shows a first interface when the first application is a game application, (b) shows a display interface when the mobile phone is converted from the folded state to the unfolded state and displays the second application (for "WeChat"), and (c) shows a display interface when the mobile phone is converted from the folded state to the unfolded state and displays the first interface. The first interface is an interface of a game matched player, the time is 30 seconds when the countdown 601 is included in the diagram, the mobile phone is changed from the folding state to the unfolding state after the second interface runs for 20 seconds in the foreground, the mobile phone displays the first interface, and the countdown 601 in the first interface is 10 seconds.

Optionally, the first interface may further include waiting information. When the mobile phone is converted from the unfolding state to the folding state, the first application can be operated in the background according to the waiting information. For example, in response to the mobile phone being converted from the unfolded state to the folded state, the mobile phone continues to run the first application in the background according to the first instruction of the waiting message. The first instruction is used for indicating the first application to continue running in the background according to the running state of the foreground.

It is to be understood that the mobile phone may further identify that the first interface is an interface of a waiting scene according to waiting information included in the first interface. For example, when the first application is a game application, the first interface may be a game player matching interface shown in (a) of fig. 6, and it is necessary to wait for other players to join the game and then start the game. For another example, when the first application is a game application, the first interface may be a waiting interface when the game character dies, and the game character can resume the game after waiting for a preset time. For another example, the first application is a video application, the first interface may be an advertisement playing interface before playing the video, and the video needs to be played after the advertisement playing time is over.

For example, the waiting information of the first interface may include a waiting time. For example, the first interface is the game player matching interface shown in (a) in fig. 6, the waiting time 601 is 30 seconds, and the waiting time 601 is the time for waiting for other players to join the game. The current scenes in the application are all waiting scenes when the user needs to wait for a period of time, and the mobile phone can identify the waiting scenes in the application.

For example, the manner of identifying the current scene of the application as the waiting scene by the mobile phone may be that a scene identification channel is set in the mobile phone, where the scene identification channel may include a function, and the scene identification channel may identify the current scene of the application. For example, a first Application runs in the foreground, and a Software Development Kit (SDK) of the first Application may establish a connection with a scene recognition channel through an Application Program Interface (API). The scene recognition channel recognizes a first interface currently displayed by the first application and determines that the interface is an interface waiting for a scene. Or, the SDK of the first application sends a display instruction to the controller of the mobile phone through the API, where the display instruction is used to indicate that the first interface of the first application is a waiting scene.

It can be understood that the mobile phone may also use other manners to identify the display interface of the first application running in the foreground as the waiting scene, and the specific manner is not limited.

For example, the mobile phone may identify waiting information in the first interface, and if it is determined that the first interface includes the waiting information, determine that the first interface is a waiting interface. The waiting information in the first interface may be a countdown icon, a waiting duration text information, a pause information, or the like. For example, when the mobile phone recognizes that the first interface includes characters such as "advertisement time", "wait for matching", "wait for revival", or "countdown", it determines that the interface is a waiting interface.

When the user uses the mobile phone, the mobile phone is in an unfolded state. If the first interface is an interface of a waiting scene, the user wants to use other applications in the waiting time of the waiting scene, the mobile phone responds to the situation that the mobile phone is changed from the unfolding state to the folding state, the main screen of the mobile phone displays the second application, and the mobile phone runs the first application in the background. In order to provide better user experience, the mobile phone may remind the user when the waiting time in the waiting scene is over or about to be over, so that the user does not miss the time when the waiting time is over.

In some embodiments, the second interface may include wait information.

Illustratively, the first interface is an interface of a waiting scene, waiting information in the waiting scene is identified, and the waiting information in the first interface is displayed on the second interface. Or identifying the waiting information in the waiting scene, determining the remaining waiting time in the waiting information, and displaying the remaining waiting time on the second interface in a countdown mode. As shown in fig. 8 (a), the second interface is a "WeChat" interface, and the waiting information in the first interface is displayed on the second interface in a countdown manner.

In some embodiments, the second interface may also display the first prompt message. And when the remaining waiting time of the waiting message is finished, the mobile phone displays the first prompt message. Or, the mobile phone displays the first prompt message within a preset time before the remaining waiting time of the waiting message is finished. The first prompt message is used for indicating that the remaining waiting time of the waiting message is finished or about to be finished.

Illustratively, the first interface is an interface of a waiting scenario, and the remaining waiting duration in the waiting scenario is identified. As shown in fig. 8 (b), when the first application continues to run in the background, the mobile phone may obtain the remaining waiting duration in the first interface in real time, and when it is determined that the remaining waiting duration is over or is about to be over, display the first prompt message in the "WeChat" application interface.

For example, during use of the mobile phone by the user, the mobile phone is in an expanded state and the first application is a game application (e.g., Royal). The interface in the game application is an interface in which a game character dies to wait for revival, as shown in fig. 9 (a). When the mobile phone detects a folding event of the user, the mobile phone is changed from the unfolded state to the folded state, and the mobile phone displays an interface of a second application, wherein the second application is ' WeChat ', as shown in (b) of FIG. 9, wherein the ' WeChat ' interface includes waiting time of ' Rong of King. After the second application runs in the foreground for a preset time, for example, 30 seconds, the mobile phone detects the expansion event of the user, the mobile phone is changed from the folded state to the expanded state, the mobile phone displays an interface of 'glory of the king person', as shown in fig. 9 (c), the game role resumes, and the game continues. Since the first application continues to run in the background, the mobile phone may obtain the waiting time in the first application, and if it is detected that the game waiting time is less than 1 second, the mobile phone displays a pop-up prompt, as shown in fig. 9 (d). The change of the display interface of the mobile phone can be switched from (a) in fig. 9 to (b) in fig. 9, and from (b) in fig. 9 to (c) in fig. 9; alternatively, the process is switched from fig. 9 (a) to fig. 9 (b), from fig. 9 (b) to fig. 9 (d), and from fig. 9 (d) to fig. 9 (c).

In other embodiments, the mobile phone may further play audio information of the first application while the mobile phone runs the first application in the background and runs the second application in the foreground to display the second interface.

In one case, the handset runs the second application without using the audio resources of the handset. The mobile phone can play the audio information of the first application running in the background by using the audio resource. For example, the second application is a reading application, the user does not use the audio resource, the first application is a game application, and the first application can play game background music by using the audio resource of the mobile phone.

In another case, the handset needs to use the audio resources of the handset to run the second application. Therefore, resource conflict exists between the audio information of the first application played by the mobile phone through the audio resource and the audio information of the second application played by the mobile phone through the audio resource. In this case, the mobile phone may use the audio resource to play the audio information of the second application running in the foreground; or, the mobile phone may use the audio resource to play the audio information of the first application running in the background in the foreground motion state; or, the mobile phone may play the audio information of the application with higher priority in the first application and the second application by using the audio resource.

For example, when the audio of the first application and the audio of the second application conflict, the mobile phone may close the audio of the first application and play the audio of the second application. For example, when the mobile phone runs the "WeChat" on the foreground and runs the "Rong Ren glory" on the background, if the user clicks the voice information sent by the WeChat friend or plays the video or audio in the WeChat application, it can be considered that the audio of the "WeChat" and the "Rong Ren glory" conflicts, and the mobile phone closes the audio of the "Rong Ren glory" and plays the audio of the "WeChat".

In other embodiments, the mobile phone may run the second application in the foreground, and may always turn off the audio of the first application when the first application is running in the background, regardless of whether the audio of the first application and the audio of the second application conflict.

The mobile phone in the embodiment of the application can respond to the change of the state and display different application interfaces. The method specifically comprises the steps of displaying an interface of a first application in an expansion state, responding to the change from the expansion state to a folding state, displaying an interface of a second application by the mobile phone, and enabling the first application to run in a background, wherein the running state of the first application in the background is consistent with the running state in a foreground. And responding to the mobile phone converted from the folded state to the unfolded state, and displaying a display interface of the first application by the mobile phone. The time utilization rate under the waiting scene can be improved, and the user experience is improved.
