A display interface can consist 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.

Specifically, the phone manager is used to provide the communication function of the electronic device. For example, the management of call status (such as connecting, hanging up, etc.).

Specifically, the resource manager can provide various resources for the application. For example, localized strings, icons, pictures, layout files, video files, etc.

Specifically, the notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also display notifications in the status bar at the top of the system in the form of a graphic or scroll bar text. In addition, the notification of the application running in the background can also be a notification that appears on the screen in the form of a dialog window. For example, text information is prompted in the status bar, a prompt sound is issued, the electronic device vibrates, and the indicator light flashes.

Specifically, the message manager can be used to store the data of the messages reported by each application program, and process the data reported by each application program.

In this embodiment of the present application, the application framework layer 360 may run an NFC service (NFCservice).

Exemplarily, after the mobile phone enables the NFC function, the NFC service can be started to run in the application framework layer. When the mobile phone approaches or touches the NFC tag, the NFC service can call the NFC driver at the kernel layer to read the binding relationship stored in the NFC tag, thereby obtaining the transfer target device for this content transfer. Further, the NFC service can report the streaming event to the above-mentioned content streaming, thereby triggering the streaming application to transmit the content that the mobile phone is running or playing as the streaming content to the streaming target device to start the content streaming process.

It should be noted that the system runtime layer 340 provides main feature support for the Android system through some C/C++ libraries. For example, the SQLite library provides database support, the OpenGL/ES library provides 3D drawing support, and the Webkit library provides browser kernel support. An Android runtime library (Android Runtime) is also provided in the system runtime library layer 340, which mainly provides some core libraries, which can allow developers to use Java language to write Android applications.

Specifically, the kernel layer 320 can provide underlying drivers for various hardware of electronic devices, such as display drivers, audio drivers, camera drivers, Bluetooth drivers, Wi-Fi drivers, power management, NFC drivers, UWB drivers, and application flow drivers , speech recognition driver, gesture recognition driver, image recognition driver, human body recognition driver, facial motion recognition driver, human motion recognition driver, etc.

The following is a specific introduction to the application flow framework of the embodiment of the present application. As shown in FIG. 4 , the application flow framework may include an information acquisition module 410 , a source and target determination module 420 , a connection management module 430 , an application information module 440 , a flow strategy module 450 and an application flow module 460 . The information acquisition module 410 may include a sensor recognition module, a voice recognition module, a gesture recognition module, an image recognition module, a human gesture recognition module, a facial motion recognition module, and/or a human motion recognition module, etc.; the application flow module 460 may include a distribution Type application framework, screen projection service framework, relay application framework, common application framework and screen projection application framework, etc.

Specifically, the acquiring information module 410 may be used to acquire the identity (ID) of one or more electronic devices through sensor recognition, voice recognition, gesture recognition, image recognition, human gesture recognition, facial motion recognition, human motion recognition, etc. information, and send the ID information of the one or more electronic devices to the source and target determination module 420 . Wherein, the above-mentioned sensors may include UWB sensors, NFC sensors, laser sensors and/or visible light sensors, etc.; the above-mentioned ID information may include Internet Protocol (Internet Protocol, IP) addresses, media access control (media access control, MAC) addresses, UWB tags, NFC tags, etc. The following takes two electronic devices, a mobile phone and a notebook computer, as examples for illustration.

For example, if UWB sensors are installed on both the mobile phone and the laptop, and each has a UWB tag (that is, ID information), when the user moves the mobile phone so that the distance between the mobile phone and the laptop is close, the UWB sensor on the mobile phone will acquire to the UWB tag of the laptop.

For another example, if both the mobile phone and the laptop are equipped with NFC sensors, and each has an NFC tag (that is, ID information), when the user touches the mobile phone by touching or leaning against the laptop, the NFC sensor on the mobile phone will The NFC tag of the laptop will be acquired.

For another example, if both the mobile phone and the notebook computer have their cameras turned on, when both the mobile phone and the notebook computer capture the current gesture action image of the user, the acquisition information module 410 analyzes the angle of the gesture in the gesture action image captured by each (such as the gesture is frontal, instead of an offset angle), the size of the gesture (such as the size of the gesture occupying the entire screen), etc., so as to select the device that meets the preset conditions from the mobile phone and laptop as the transfer source device or transfer target device, and obtain the transfer ID information of the source device or ID information of the transfer destination device. For example, in the respective captured gesture action images, the real flow source device (the flow target device) captures images with more gestures facing the front, rather than having an offset angle; or, the gestures in the captured images The larger the proportion is, the more likely it is the real source device (target device). Therefore, the preset condition can be understood as the gesture orientation in the image is more toward the front, or the gesture occupies a larger proportion in the image, etc.

Specifically, the source and target determination module 420 may be configured to determine the ID information corresponding to the transfer source device and the ID information corresponding to the transfer target device from the ID information of the one or more electronic devices from the information acquisition module 410 . It should be noted that the ID information sent by the information acquisition module 410 to the source and target determination module 420 may contain ambiguous transfer source devices and transfer target devices (ie, transfer objects), resulting in inability to perform application transfer. At this time, it needs to be judged by the source and target judgment module 420 . If there is a clear result of the transfer source device and the transfer target device, the result is sent to the transfer strategy module 440 to execute the application transfer strategy from the transfer source device to the transfer target device; if there is no clear transfer source device and transfer target device. As a result, the connection management module 430 is accessed. The following takes a mobile phone as the circulation source device for illustration.

For example, when the mobile phone recognizes a piece of voice input by the user that "transfer the video image of the machine to the computer", the voice recognition module in the mobile phone recognizes the voice and transmits the recognition result to the source and target determination modules. Since there may be communication connections between the mobile phone and multiple devices (such as notebook computers, desktop computers, etc.), the source and target determination modules in the mobile phone cannot determine a clear transfer target device from the identification result.

Specifically, the connection management module 430 may be configured to acquire ID information of all devices connected to the circulation source device under the same user account or the same network. Wherein, the connection management module 430 can access the remote or cloud server or other electronic devices to obtain the above ID information, can access the internal memory of the local end to obtain the above ID information, and can also access the external memory interface to obtain the above ID information. No specific restrictions are imposed.

Specifically, the application information module 440 may be used to identify a currently running application to obtain application information of the application. The application information may include an application name, an application type, and the like. It should be noted that the application information module 440 can obtain application information of the application currently running on the front end (eg, UI interface) or the back end by accessing a process or thread.

In addition, the embodiments of the present application divide the above application types into the following four categories: screen-casting applications, distributed applications, relay applications, and common applications. Among them, screen-casting applications refer to applications that continue to run on the streaming source device, and are projected from the streaming source device to the streaming target device, and then run by the streaming target device; distributed applications refer to the front-end and back-end of the application. Applications that can realize separate operation operations on different devices; relay applications refer to applications that can realize storage, recovery or sharing operations on different devices through the file service on the local end; common applications refer to screen projection technology. Applications that implement display operations on different devices, and ordinary applications can include screen-casting applications.

Specifically, the flow strategy module 450 may be configured to determine the application flow strategy from the flow source device to the flow target device according to the application type, and transmit it to the application flow module 460 . It should be noted that the circulation strategy module 450 can access the application information module 440 to learn the application type of the currently running application, so as to determine different application circulation strategies according to different application types.

Specifically, the application flow module 460 may be configured to perform cross-device flow of application content according to an application flow policy. It should be noted that different application flow strategies need to be adopted for different application types, and different application flow strategies correspond to different application frameworks. For example, when performing application transfer for distributed applications, a distributed application framework needs to be used; when performing application transfer for relay-type applications, a relay-type application framework needs to be used; when performing application transfer for screen-casting applications, it is necessary to adopt a relay-type application framework. screen service framework or screen-casting application framework; when performing application transfer for common applications, the screen-casting service framework or common application framework needs to be used.

At present, the solution for the cross-device flow of application content only supports a single software and hardware, and there is no module or framework to integrate multiple software and hardware to achieve collaborative operation. At the same time, the current solution only supports screen projection or simple data transmission, and cannot support the flow of richer distributed applications or relay applications, and cannot support the flow of applications between different application types at the same time. Therefore, through the application transfer framework shown in FIG. 4 , the embodiment of the present application can obtain information through different identification modules, and determine the ID information of the transfer source device and the ID information of the transfer target device from the acquired information to determine the transfer object, Then, different application flow strategies are adopted according to the application type of the currently running application, so as to realize more convenient flow of application content across devices, and to improve the efficiency of application flow and use experience. The following embodiments of the present application will be specifically described in terms of method examples.

In combination with the above description, the following describes the execution steps of the method for transferring application content across devices from the perspective of a method example, please refer to FIG. 5 . 5 is a schematic flowchart of a cross-device flow method for application content provided by an embodiment of the present application, which is applied to a flow source device. The method includes: S510 : Obtain an application type of a target application currently running on the flow source device.

It should be noted that a target application is currently running on the streaming source device in the embodiment of the present application, and the target application may be an application program or media data running on the application layer of the streaming source device, such as photos, videos, audios, games, Gallery, document or multimedia, etc. In addition, the circulation source device can run the target application on the front end, and can also run the target application on the back end. When the streaming source device runs the target application at the front end, the display screen of the streaming source device may display the current content of the target application; when the streaming source device runs the target application at the back end, the display screen of the streaming source device may not display the target application. The current content of the target application, and the target application continues to be executed in the background.

In a possible example, before S510, the method may further include the following steps: acquiring first information, and judging whether the first information carries identification information of the transfer target device.

Specifically, the first information may satisfy at least one of the following manners: the first information is acquired by sensor recognition, the first information is acquired by voice recognition, the first information is acquired by gesture recognition, the first information is acquired by image Recognition and acquisition, the first information is acquired through human gesture recognition, the first information is acquired through facial motion recognition, and the first information is acquired through human motion recognition; wherein, the above sensors may include at least one of the following: ultra-bandwidth UWB sensor, near field communication NFC sensor, laser sensor, visible light sensor.

It should be noted that, in order to realize the cross-device transfer of application content between the transfer source device and the transfer target device in this embodiment of the present application, the transfer object (ie the transfer source device and/or the transfer target device) needs to be determined first. Therefore, when the embodiment of the present application considers transferring the content of the target application currently running on the transfer source device, the transfer source device obtains the first information, and determines whether the first information carries the identification information of the transfer target device, so as to realize The transfer destination device is determined by the transfer source device. At this time, in combination with the application flow framework in FIG. 4, the embodiment of the present application can obtain the first information through the information obtaining module in the flow source device, and determine the first information through the source and target determination module in the flow source device. Whether the information carries the identification information of the transfer target device. In the following, an example is given by taking the transfer source device as a mobile phone as an example.

For example, when a UWB sensor is installed on a mobile phone, the user places the mobile phone near a laptop and a smart watch that are also equipped with UWB sensors, so as to obtain the UWB tag of the laptop and the UWB tag of the smart watch. At this point, laptops and smartwatches can be considered as candidate transfer target devices. The display of the phone can then display a list of options including the laptop and the smartwatch through pop-up windows, drop-down menus, and the like. Finally, the user can select one or more devices from the option list as the transfer target device, so that the mobile phone obtains the specific ID information of the transfer target device (ie UWB tag, MAC address or IP address, etc.).

For another example, when an NFC sensor is installed on a mobile phone, the user touches the mobile phone by touching (or leaning against, etc.) a laptop and a smart watch that are also equipped with an NFC sensor, so as to obtain the NFC tag of the laptop. , and NFC tags for smartwatches. At this point, laptops and smartwatches can be considered as candidate transfer target devices. Then, the display screen of the mobile phone can display a list of options including the laptop computer and the smart watch by means of pop-up windows, drop-down menus, and the like. Finally, the user can select one or more devices from the option list as the transfer target device, so that the mobile phone obtains the specific ID information (ie NFC tag, MAC address or IP address, etc.) of the transfer target device.

For another example, when a laptop computer is connected to the current user account of the mobile phone, the mobile phone can issue an instruction to make the laptop computer turn on the camera. At this time, if the laptop computer captures the user's current gesture action image (such as gesture release action, gesture capture action, hand wave action, left-right hand wave action, "OK" gesture action, etc.), the laptop computer analyzes the captured gesture Whether the motion image meets the preset gesture conditions. If the preset gesture conditions are met, the notebook computer is used as the transfer target device, and the notebook computer sends its own MAC address or IP address to the mobile phone, so that the mobile phone obtains the clear ID information of the transfer target device (that is, the MAC address). address or IP address, etc.). It should be noted that when the user really needs to stream the content of the application running on the mobile phone to the laptop, the user will explicitly perform a gesture action in the direction of the camera facing the laptop. Therefore, when analyzing the gesture action images captured by the notebook computer, the real flow target device captures images with more gestures facing the front, rather than having an offset angle; or, gestures occupy more of the captured images The larger the ratio, the more likely it is the real transfer target device. Therefore, the preset gesture condition can be understood as the more positive the gesture in the picture is, or the larger the proportion of the gesture in the picture, etc.

It can be seen from the above three examples that the first information acquired by the transfer source device may directly carry the ID information of the transfer target device. However, the first information acquired by the information acquisition module in the transfer source device by recognizing voice, image, human posture, facial motion, human motion, etc. may not carry the identification information of the transfer target device. In the following, an example is given by taking the transfer source device as a mobile phone as an example.

For example, when the mobile phone recognizes a piece of voice inputted by the user that "transfer the video screen of the machine to the computer", if there is a communication connection between the mobile phone and multiple devices (such as laptop computers, desktop computers, etc.), the mobile phone will recognize The voice is used to obtain the first information, but it cannot be clearly identified from the first information to which computer or computers the video image stream of the local machine is transferred to, so that the mobile phone cannot be determined from the first information. The transfer target device.

For another example, when the current user account of the mobile phone is also connected to the laptop computer A and the laptop computer B, the mobile phone can issue an instruction to make the laptop computer A and the laptop computer B turn on the cameras. At this point, if both laptop computer A and laptop computer B have captured the current facial motion picture of the user (such as a smile, pursed lips, etc.), both laptop computer A and laptop computer B will analyze the facial motion pictures captured by them. Whether the preset face conditions are met. If neither of the preset face conditions are met, neither laptop A nor laptop B will send their respective MAC addresses or IP addresses to the mobile phone, so that the mobile phone cannot obtain the clear ID information of the target device (that is, the MAC address). address or IP address, etc.). It should be noted that when the user really needs to stream the content of the application running on the mobile phone to the laptop computer A, the user will make a facial action in the direction of the camera facing the laptop computer A. At this time, the pictures with more faces facing the front are captured by the laptop computer A instead of having an offset angle; or, the larger the proportion of faces in the captured pictures. However, since the user does not perform facial movements in the direction facing the camera of the notebook computer B, the face captured by the notebook computer B has a large oblique angle and the like. Therefore, the preset face condition can be understood as the more frontal the face in the picture faces, or the larger the proportion of the face in the picture, etc.

In the following embodiments of the present application, an example will be described for the case where the first information does not carry the identification information of the transfer target device.

In a possible example, after judging whether the first information carries the identification information of the transfer target device, the method further includes the following steps: when the first information does not carry the identification information of the transfer target device, obtain the current user of the transfer source device Identification information of all devices connected to the transfer source device under the account; the identification information of the transfer target device is determined from the identification information of all devices.

It should be noted that, when the embodiment of the present application considers transferring the content of the target application currently running on the transfer source device, if the first information obtained by the transfer source device does not carry the ID information of the transfer target device, in conjunction with the above Figure 4 The application transfer framework in the embodiment of the present application can obtain the ID information of all devices connected to the transfer source device under the current user account of the transfer source device through the connection management module in the transfer source device.

It should be further noted that, since the identification information of all devices connected to the source device under the current user account of the source device is stored on the server at the remote end or in the cloud, the source device can access the server at the remote end or in the cloud. to obtain the above-mentioned ID information; or, because other remote electronic devices (such as routers or relay devices, etc.) store the identification information of all devices connected to the source device under the current user account of the source device, this The circulation source device can access other remote electronic devices to obtain the above-mentioned ID information; or, because the above-mentioned server or the above-mentioned other electronic equipment can directly issue the above-mentioned ID information to the internal memory of the circulation source device for caching to improve access efficiency, so The streaming source device can directly access the internal memory of the local end to obtain the above ID information; or, since the above ID information can be copied to the external memory, the streaming source device can access the external memory interface to obtain the above ID information.

It can be seen that the ID information of all devices under the same user account as the source device is obtained through the above different access methods to determine the target device, so as to ensure the more convenient realization of the cross-device transfer of application content and improve the efficiency of application transfer. , variety and experience.

In addition, for the current user account of the transfer source device, it can be known from the application content transfer communication system 10 described above that each electronic device in the at least two electronic devices 110 can be a device under the same user account. For example, when the user uses the same user account to log in to devices such as mobile phones, desktop computers, and smart watches, the at least two electronic devices 110 include the mobile phones, desktop computers, and smart watches, and the mobile phone, desktop computers, and smart watches. Devices can communicate with each other over a wireless network. At this time, the circulation source device may be understood as one of the at least two electronic devices 110 .

In a possible example, after judging whether the first information carries the identification information of the transfer target device, the method further includes: when the first information does not carry the identification information of the transfer target device, obtaining the network and the network where the transfer source device is located. The identification information of all devices connected to the transfer source device; the identification information of the transfer target device is determined from the identification information of all devices.

It should be noted that, when the embodiment of the present application considers transferring the content of the target application currently running on the transfer source device, if the first information obtained by the transfer source device does not carry the ID information of the transfer target device. At this time, in conjunction with the application flow framework in FIG. 4, the embodiment of the present application can obtain the ID information of all devices connected to the flow source device in the network where the flow source device is located through the connection management module in the flow source device .

It should be further noted that, with respect to the network where the transfer source device is located, it can be known from the application content transfer communication system 10 described above that each electronic device in the at least two electronic devices 110 can be connected to the same device through a relay device (such as a router). in a WLAN network. Alternatively, each of the at least two electronic devices 110 may form a peer-to-peer (P2P) network through wireless communication (eg, Bluetooth, Zigbee, NFC, UWB, etc.). Therefore, the network where the transfer source device is located may be a WLAN network or a P2P network formed by a relay device or a wireless communication method.

In addition, if the network where the transfer source device is located is a WLAN network, the transfer source device can access the remote relay device to obtain the above ID information; or, the remote relay device directly sends the above ID information to the transfer device Cached on the internal memory of the source device, the streaming source device can directly access the internal memory of the local end to obtain the above ID information. If the network where the transfer source device is located is a P2P network, the transfer source device can access the main electronic device in the P2P network (such as a device with strong computing power, the device closest to the transfer source device, or the main control device in the P2P network, etc.) To obtain the above-mentioned ID information; or, the main electronic device directly sends the above-mentioned ID information to the internal memory of the circulation source device to be cached, and the circulation source device can directly access the internal memory of the local end to obtain the above-mentioned ID information. If the above-mentioned ID information can be copied to the external memory, the streaming source device can access the external memory interface to obtain the above-mentioned ID information.

It can be seen that the ID information of all devices connected to the source device in the network where the source device is located can be obtained through the different access methods described above to determine the target device, so as to ensure a more convenient transfer of application content across devices and improve application performance. Efficiency, variety and user experience of circulation.

The following embodiments of the present application will specifically describe how the transfer source device determines the identification information of the transfer target device from the identification information of all devices.

Specifically, determining the identification information of the transfer target device from the identification information of all devices may include the following steps: if the identification information of all devices except the identification information of the transfer source device only has the identification information of one device, then the device The identification information of the transfer target device is used as the identification information of the transfer target device.

It should be noted that when there is only one device for all devices connected to the circulation source device under the same user account, or when there is only one device for all the devices connected to the circulation source device in the same network, the embodiment of the present application may consider The device is used as the streaming target device, and the ID information of the device is acquired, so that the streaming source device can realize the streaming of the content of the currently running target application to the device.

Specifically, determining the identification information of the transfer target device from the identification information of all the devices may include the following steps: if the identification information of all the devices contains the identification information of at least two devices in addition to the identification information of the transfer source device, obtain the identification information for the transfer target device. A selection operation instruction for the identification information of at least two devices; the identification information of the transfer target device is determined from the identification information of the at least two devices according to the selection operation instruction.

It should be noted that when there are at least two (ie multiple) devices for all devices connected to the source device under the same user account, or there are multiple devices for all devices connected to the source device in the same network , the embodiment of the present application considers that a list of options including the multiple devices is displayed on the display screen of the streaming source device by means of a pop-up window, a drop-down menu, or the like. The user can then select one or more devices from the list of options as the streaming target device. That is to say, the streaming source device can obtain a selection operation instruction for the plurality of device ID information, so as to determine the ID of the streaming target device according to the selection operation instruction, and realize the content of the currently running target application by the streaming source device. Streaming to the streaming target device. In the following, an example is given by taking the transfer source device as a mobile phone as an example.

Illustratively, as shown in FIGS. 6 and 7 . In Fig. 6, a music player (ie, a target application) is currently running on the mobile phone. At this point, the user needs to stream the song "don't think of me" (that is, the content of the target application) currently playing on the music player to the laptop for playback. At this point, the user starts to prepare for the cross-device flow of the application content by clicking the "transfer application" option on the mobile phone. In Fig. 7, after the user clicks the "transfer application" on the mobile phone shown in Fig. 6, the user accesses the network from a wide area network (all devices under the same user account are connected through a wide area network) or a local area network (such as a WLAN network or a P2P network). Laptop A and Laptop B are found. At this time, the MAC address of laptop A (ie 00:0C:29:26:BC:07) and the MAC address of laptop B (ie 00:0C:29:F3:54:1D) are transmitted through the above network to the phone. Then, a list of options including the MAC address of the laptop computer A and the MAC address of the laptop computer B is displayed on the mobile phone by means of a pop-up window. Finally, the user can select Laptop A as the streaming target device from the list of options.

It can be seen that when there are multiple devices, in this embodiment of the present application, the user can select the multiple devices to determine the streaming target device, thereby improving the use experience of application content streaming across devices.

Specifically, determining the identification information of the transfer target device from the identification information of all the devices may include the following steps: if the identification information of all the devices contains the identification information of at least two devices in addition to the identification information of the transfer source device, according to the predetermined The priority policy is to use the identification information with the highest priority among the identification information of at least two devices as the identification information of the transfer target device.

It should be noted that when there are multiple devices for all devices connected to the circulation source device under the same user account, or when there are multiple devices for all the devices connected to the circulation source device in the same network, the embodiment of the present application Consider determining the identification information of the transfer target device from the identification information of all devices according to a preset priority policy.

Several implementations of the preset priority policy in the embodiment of the present application will be specifically described below.

Way 1:

Among them, the number of times that the notebook computer has had an application flow with the mobile phone in the history is 1, and the number of times that the smart watch has had an application flow with the mobile phone in the history is 0. Therefore, according to the above preset priority policy, the laptop has the highest priority.

Way 3:

Further, the preset priority policy may include setting all devices in the P2P network (ie, a network formed by wireless communication methods such as Bluetooth, Zigbee, NFC, UWB) where the transfer source device is located as the highest priority.

Illustratively, taking a mobile phone as the source device for circulation as an example, the mobile phone and the notebook computer form a P2P network by means of Bluetooth, and the mobile phone and the smart watch form a WLAN network by connecting to the same router. Therefore, according to the above preset priority policy, the laptop has the highest priority.

Illustratively, taking a mobile phone as the source device for circulation as an example, the mobile phone and the notebook computer form a P2P network by means of Bluetooth, and the mobile phone and the smart watch form a WLAN network by connecting to the same router. Therefore, according to the above preset priority strategy, the smart watch has the highest priority.

Way 5:

Further, the preset priority policy may include setting all devices under the same user account as the transfer source device to have the highest priority.

Exemplarily, taking a mobile phone as the source device for circulation as an example, the mobile phone and the laptop are two devices under the same user account, and the mobile phone and the laptop are connected to each other, and the mobile phone and the smart watch are connected to the same Routers form a WLAN network. Therefore, according to the above preset priority policy, the laptop has the highest priority.

Way 6:

Further, the preset priority policy may include preferentially selecting all devices in the P2P network where the source device is located, and then determining the identification information of the destination device from all the above-mentioned devices according to the selection operation instruction; or, preferentially selecting the location where the source device is located. All devices in the P2P network, and then determine the time of application transfer with the transfer source device in history from all the above devices, and set the device with the latest time in the time of application transfer with the transfer source device as the highest priority. ; Or, give priority to all devices in the P2P network where the source device is located, and then judge the number of times the application has been transferred with the source device in history from all the above-mentioned devices, and the number of times the application has been transferred with the source device will be counted. The device with the highest number of times is set to have the highest priority.

It should be noted that, in this embodiment of the present application, the above various implementation manners may be combined to determine a preset priority policy, which will not be described in detail.

It can be seen that the embodiment of the present application can determine the identification information of the transfer target device from the identification information of all devices through the above different implementations, thereby improving the efficiency and use experience of the application content transfer across devices.

With reference to the above description, S510 in this embodiment of the present application may include the following steps: when the first information carries the identification information of the transfer target device, obtain the application type of the target application currently running on the transfer source device.

It should be noted that, when the embodiment of the present application considers transferring the content of the target application currently running on the transfer source device, if the first information obtained by the transfer source device carries the ID information of the transfer target device, in combination with the above-mentioned FIG. 4 The application circulation framework of this application embodiment can identify the currently running target application through the application information module in the circulation source device to obtain application information (such as application name, application type, etc.) of the target application. In addition, the application information module in the transfer source device can access the process or thread on the operating system of the transfer source device to obtain the application type of the target application.

Specifically, the application type of the target application may include at least one of the following: distributed application, relay application, and common application.

Further, the distributed application can be used to instruct the front end of the target application and the back end of the target application to implement separate running operations on different devices.

It should be noted that when the target application is a distributed application, the backend of the target application needs to be run on the source device, and the frontend of the target application is transferred to the target device, and the target device runs the frontend of the target application. , without having to re-run the source device.

Further, the relay application can be used to instruct the target application to implement storage, transfer, recovery or sharing operations on different devices through the file service on the streaming source device.

It should be noted that when the target application is a relay application, the file server (fileServer) on the streaming source device can stream the content of the target application (such as data stream, video stream, audio stream, etc.) to the streaming target device, and then The streaming target device accesses the file service on the streaming source device to restore the content of the target application. Among them, the file service can provide an http access address, and provide it to an external application or a third-party cooperative application in the form of a data stream. For example, an external application or a third-party cooperative application can access the local multimedia data through the http access address.

Exemplarily, taking a mobile phone as the streaming source device as an example, a video player in the mobile phone is playing a local video file. When the user needs to relay the local video file played on the video player to the laptop, the mobile phone transmits data stream information such as the video name of the local video file, the http address of the video, and the playback progress through the relay application framework. to that laptop. However, after the notebook computer receives the data stream information, a notification box pops up, and the user is prompted through the notification box whether to relay the video from the mobile phone. If the user decides to execute the relay, the laptop will run the video player on the local end, and the video player will access the file service on the mobile phone through the http address of the video in the received data stream information to obtain the local video The file is restored (for example, the video is resumed), and the playback of the local video file is stopped on the mobile phone.

Further, the common application can be used to instruct the target application to implement display operations on different devices through the screen projection technology.

It should be noted that when the target application is a common application, the streaming source device can project the content of the target application to the display screen or display medium of the streaming target device for display, thereby displaying the synchronous display of the content.

S520. Determine an application flow strategy for the target application according to the application type.

It should be noted that when the embodiment of the present application considers transferring the content of the target application currently running on the transfer source device, if the transfer source device has already learned the ID information of the transfer target device, in combination with the application transfer framework in FIG. 4 above, In this embodiment of the present application, the application information module can be accessed through the circulation policy module in the circulation source device to learn the application type of the target application, so as to determine the corresponding application circulation policy according to the application type of the target application.

The following embodiments of the present application specifically describe several implementation manners in which different application flow strategies are determined by different application types of target applications.

Way 1:

In a possible example, if the application type includes a distributed application, determining an application flow strategy for the target application according to the application type may include the following steps: determining an application flow strategy according to the distributed application; wherein the application flow strategy is used to execute The following steps: Pause the front end of the target application from running on the streaming source device, and the streaming target device accesses the back end of the target application running on the streaming source device to start running the front end of the target application.

It should be noted that when the target application is a distributed application, the application flow strategy can be: the backend of the target application continues to run on the source device, and the front end of the target application is transferred to the target device, and stops running the target itself. The front end of the application; the streaming target device accesses the back end of the target application running on the streaming source device to start running the front end of the target application. The following takes two electronic devices, a mobile phone and a notebook computer, as examples for illustration.

For example, see Figure 8. The phone is currently running distributed application X. Among them, the UI interface and server side of application X are both running. When the mobile phone points to the laptop through UWB, after passing through the distributed application framework, the mobile phone suspends the running of the UI interface of the application X, and the laptop starts to run the UI interface of the application X by accessing the server of the application X on the mobile phone.

In addition, combined with the application flow framework in Fig. 4, the UBW identification module in the mobile phone shown in Fig. 8 obtains the UWB label of the notebook computer, and sends the UWB label of the notebook computer to the source and target determination modules. Then, the source and target determination module transmits the UWB tag of the mobile phone and the UWB tag of the notebook computer to the circulation strategy module, and the circulation strategy module accesses the application information module to know that the application X currently running on the mobile phone is a distributed application. Finally, the flow strategy module initiates an application flow request to the distributed application framework in the application flow module, so as to suspend the UI interface of the application on the mobile phone through the distributed application framework, pull up the UI interface of the application X on the laptop, and notify the notebook When the computer starts to run the UI interface of application X, it accesses the server of application X on the mobile phone, so as to complete the cross-device transfer process of application X.

Way 2:

In a possible example, if the application type includes a relay application, determining the application flow strategy for the target application according to the application type may include the following steps: determining the application flow strategy according to the relay application; wherein, the application flow strategy is used to execute The following steps: Pause the target application from running on the streaming source device, and the streaming target device accesses the file service of the streaming source device to start running the target application.

It should be noted that when the target application is a relay application, the application transfer strategy may be: the file service on the transfer source device transfers the content of the target application (such as data stream, video stream, audio stream, etc.) to the transfer target device; The streaming target device accesses the file service on the streaming source device to start running the content of the target application. Among them, the file service can provide an http access address, and provide it to an external application or a third-party cooperative application in the form of a data stream. The following takes two electronic devices, a mobile phone and a notebook computer, as examples for illustration.

For example, see Figure 9. Run a video player on the phone to play a local video file. When the user enters the voice of "playing on the laptop" into the mobile phone through the microphone of the mobile phone. The mobile phone analyzes the voice to learn that the source device of the stream is a laptop. Finally, after passing the relay application framework, the mobile phone pauses to play the local video file on the local video player, and the laptop starts playing (or continues to play) the video file on the local video player by accessing the file service on the mobile phone. Local video files (i.e. the laptop plays the same video as the phone).

In addition, combined with the application flow framework in FIG. 4 , the speech recognition module in the mobile phone shown in FIG. 9 recognizes the “playing on the laptop” speech, and transmits the recognition result to the source and target determination modules. Secondly, since the source and target determination modules cannot know the ID information of the laptop through the identification result, the source and target determination modules access the connection management module to query all devices connected to the mobile phone within the same user account or the same network. ID information. Thirdly, since there is only one laptop connected to the mobile phone, the source and target determination module obtains the ID information of the laptop, and transmits the ID information of the mobile phone and the laptop to the circulation strategy module. Next, the circulation strategy module accesses the application information module to know that the video player currently running on the mobile phone is a relay application. Finally, the flow strategy module initiates an application flow request to the relay application framework in the application flow module, so as to pause the video playback on the video player of the mobile phone through the relay application framework, and the laptop accesses the file service on the mobile phone to play the video The video player on the local end continues to play the same video as that on the mobile phone.

Way 3:

In a possible example, if the application type includes a common application, determining an application flow strategy for the target application according to the application type may include the following steps: determining the application flow strategy according to the common application; wherein the application flow strategy is used to execute The following operations: If there is an application compatible with the target application and the content of the target application to be synchronized on the streaming target device, suspend the target application from running on the streaming source device, and project the content of the target application to the display screen or display medium of the streaming target device Or, if there is no application compatible with the target application on the streaming target device or does not support synchronizing the content of the target application, continue the target application to run on the streaming source device, and project the content of the target application to the display screen of the streaming target device or displayed on the display medium.

It should be noted that when the target application is a common application, the application transfer strategy may be: the source device of the transfer projects the content of the target application to the display screen or display medium of the target device for display through the screen projection service framework, and judges that the content of the target application is displayed. Whether there is an application compatible with the running of the target application and supports synchronization of the content of the target application on the streaming target device; if there is an application that is compatible and supports synchronization, the streaming source device can suspend running the target application; if no application is compatible or supports synchronization, the streaming source device The target application can continue to run.

In addition, the target application of this embodiment of the present application may be an application program or media data running on the application layer of the streaming source device, such as photos, videos, audios, games, gallery, documents, or multimedia. At the same time, the circulation source device can run the target application on the front end, and can also run the target application on the back end. When the streaming source device runs the target application at the front end, the display screen of the streaming source device can display the content of the target application; when the streaming source device runs the target application at the back end, the display screen of the streaming source device may not display the target application The content of the application, while the target application is executed in the background. The following takes two electronic devices, a mobile phone and a notebook computer, as examples for illustration.

For example, see Figure 10. The phone is currently running the normal application Y. When the mobile phone touches the notebook computer through NFC, after passing the screen casting service framework, the mobile phone projects the content of the running application Y to the display screen of the notebook computer for display. Since there is no compatible app running with app Y on the laptop, the phone needs to continue running app Y.

It should be further noted that, in this embodiment of the present application, the content projected by the streaming source device on the display screen of the streaming target device may be referred to as a mirror image, and the mirror image may present all or part of the content of the target application. At the same time, the mirror image may be a picture presented after relevant operations such as resolution adjustment, display size adjustment, pixel adjustment, and image quality adjustment in the process of screen projection. The following is an example description by taking the transfer source device as a notebook computer and the transfer target device as a mobile phone.

Illustratively, see FIGS. 11 and 12 . In Figure 11, the user opens a photo of "cat.jpg" through the "Gallery" application on the laptop, and uses the screen mirroring service framework or the normal application framework to transfer the content of the "Gallery" application on the laptop (ie Photo screen) is projected to the mobile phone. At this time, the screencast content displayed on the display screen of the mobile phone is the same as the content of the "Gallery" application on the laptop computer (that is, the mirror image can present the entire screen of the content of the target application). However, in Fig. 12, the user can screen only the "cat.jpg" opened by the "Gallery" application on the laptop to the mobile phone by setting the relevant screen projection options. At this time, the screencast content displayed on the display screen of the mobile phone is only a partial picture of the content of the "Gallery" application (that is, the mirror image can present a partial picture of the content of the target application), such as showing the whole body or part of the entire "cat".
