The electronic device may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or devices connected to a wireless modem. Other processing equipment, and various forms of user equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal equipment (terminal device), etc.

The following describes the embodiments of the present application in detail.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for starting a camera provided in an embodiment of the present application, which is applied to an electronic device. The camera startup method includes:

S101. The electronic device obtains a selection operation for an application icon of a camera application on a desktop.

Among them, in the prior art, the process of enabling the camera is that when the user clicks on the application icon of a certain camera application, the desktop determines whether it is a camera application, and if so, sends the intent intent to the system service, and the system service completes the intent. After parsing, the camera application process is created. The camera application will read the identification of the camera that currently needs to be opened, and then execute the opening of the camera, so that the camera is opened and the camera application interface is presented as a camera preview interface. This series of operations are all serial. Therefore, from a visual point of view, the user cannot see the camera preview interface immediately after opening the camera application, because the camera may not be opened yet.

Among them, different from the prior art, in the camera startup method provided by the embodiments of the present application, when the selection operation for the application icon of the camera application on the desktop is obtained, the first thread and the second thread are started at the same time. Two threads can complete the work of the above one thread, thereby saving part of time and improving the startup efficiency of the camera application.

S102: The electronic device starts a first thread and starts the camera application through the first thread to display a camera preview interface.

Among them, camera applications are camera applications. Camera applications include system camera applications and third-party camera applications. Generally, system camera applications can present a camera preview interface after opening the application. For some third-party camera applications, some The camera preview interface may be displayed directly after opening the application, such as the light camera, B612 camera, and other applications, and some may display the camera preview interface after opening the application after corresponding operations, such as beauty Camera, Meitu Xiuxiu and other applications. The camera application in this application mainly refers to an application that can directly present a camera preview interface after opening the camera application.

S103: The electronic device simultaneously starts a second thread and notifies the system service to perform a preset operation through the second thread to start the target camera associated with the camera application.

Among them, the intent is mainly to solve the communication between the various components of the Android application, and is responsible for describing the action of an operation in the application, the action related data, and additional data. The system service can find the corresponding component according to the description of the intent, and Pass the intent to the called component and complete the invocation of the component. Therefore, the intent acts as a media intermediary, specifically providing information about the mutual invocation of components. For example, the intent is used to tell the system to open a certain camera. This action corresponds to the rear camera 1. The system can determine whether to open the rear camera 1 based on this intent. After detecting the selection operation of the application icon for the desktop, the system service will receive an intent related to the application icon. The system service can determine whether the selected application is a camera application based on the received intent. If it is, You need to start two threads to open the camera application and the camera respectively. If not, you only need to start one thread to open the application.

Among them, under normal circumstances, starting the camera application is also executed by the system service, and then the camera application opens the camera, and in this application embodiment, after starting the first thread to start the camera application, it can also be started The second thread, the second thread can notify the system service to perform preset operations to open the target camera, that is, the system service uses two threads to realize opening the camera application and opening the target camera associated with the camera application, instead of waiting for the camera application After startup, the camera application executes to turn on the camera.

In a possible example, the system service determines whether the selected application is a camera application according to the received intent, including: the system service reads the application package name of the camera application after parsing the intent; The system service determines whether the camera application is a camera application according to the application package name.

Among them, the core role of Intent in Android is to jump, and it can carry necessary information at the same time, using intent as an information bridge. Intent needs to indicate where this communication request comes from, where to go, how to go, and the initiator carries the data content of this communication request, the receiver unpacks the received intent packet, and if the initiator requests to judge the reception As a result of the processing by the party, the intent is responsible for allowing the receiver to return the response data content. After receiving the intent sent by the desktop, the system service analyzes the intent and reads the analysis result, and can determine whether the camera application is a camera application according to the application package name of the camera application selected by the user. In fact, before the two threads are executed at the same time, it is known that the camera application is targeted, but in the second thread, it will be judged again whether the target object is a camera application.

It can be seen that in this example, in the second thread, by parsing the intent and reading the application package name of the camera application, it can be determined again whether the current target application is a camera application, and at the same time, the camera application can also be obtained Related information, determine the target task is to open the camera of the camera application.

In a possible example, when the system service detects that the selected application is the camera application, opening the target camera associated with the camera application includes: the system service determines whether the camera application is Have the authority to open the camera of the electronic device; if so, the system opens the target camera with this service.

Among them, for camera applications, some applications may have the permission to use the camera of the electronic device, and some applications do not have the permission to use the camera, and the electronic device has at least one front camera and at least one rear camera. The user can set it so that Some applications (such as camera applications dedicated to facial beautification) only have the permission to use the front camera. The advantage of this is that the front camera can be used directly when opening such applications. Similarly, some applications can You only have permission to use the rear camera. The advantage of this is that you can directly use the rear camera when opening such applications. The system service will detect whether the camera application has permission to open the target camera, and if so, will it agree to open the target camera in advance.

Among them, for camera applications with a higher security level, you can set that only the camera application can open the camera of the electronic device. For example, after opening the camera application, the user is required to perform identity verification, and the camera can be turned on after the identity verification is passed. For camera-like applications, the system service does not have the permission to open the camera before the application is fully started.

It can be seen that in this example, because the camera application in the first thread has not been fully successfully started at this time, the system service needs to determine whether there is permission to open the camera before opening the camera. If so, perform the opening camera application association If it is not the target camera, the second thread is ended, and the camera application is executed to open the camera.

In a possible example, when the system service detects that the selected application is the camera application, opening the target camera associated with the camera application includes: the system service reads the target camera And determine the target camera according to the identity; the system service calls the camera open program and opens the target camera.

Among them, each camera application is associated with a target camera. Since the electronic device has multiple cameras, when using the camera application, the user can determine which camera is currently being used through settings. After exiting the application, when the camera application is opened again, Directly use the camera used before closing the application last time, that is, the target camera. For example, the electronic device has four cameras, and each camera corresponds to an identity. When the camera application was exited last time, the second camera was used. Therefore, the second camera is the target camera associated with the camera application, and the system service reads the target After the identification of the camera, you can know that the second camera is to be opened. The system service opens the target camera by calling the camera open program. Among them, if the program requests camera open during operation but does not actually obtain the permission to operate the camera, it will cause the camera open to fail to open all the time. Therefore, the target camera has the permission to open camera.

It can be seen that in this example, in the process of opening the camera by the system service, by reading the identity of the target camera, it is determined which camera of the electronic device the target camera to be opened is, so that the copper drum can call the camera open program to open the target camera.

In a possible example, after the system service opens the target camera associated with the camera application, the method further includes: notifying the system service to send a notification message to the camera application through the second thread, and ending In the second thread, the notification message is used to notify the camera application that the target camera has been opened.

Among them, in the second thread, after the target camera is opened, the second thread will notify the system service to send a notification message to the camera application function, and terminate the second thread. At this time, the first thread is still running. After the camera application is opened in the first thread, the camera application will receive this notification message to know that the camera has been opened.

It can be seen that in this example, a notification message is sent to the camera application being started by the first thread through the second thread to inform the camera application that the target camera is already open at this time, so that in the first thread, the camera application does not need to be opened after it is started. The target camera, but directly uses the target camera that has been opened, which is conducive to the camera application interface can quickly present the camera preview interface.

In a possible example, the method further includes: informing the camera application to turn on the target camera when it is detected that the camera application has not received the notification message through the first thread.

Among them, if in the first thread, it is detected that the camera application has received a notification message, the camera application function does not know whether the camera is turned on at this time, it may have been turned on but the notification message has not been received, or it may not have been turned on and therefore cannot be received Notification message, at this time, the camera application needs to take the initiative to open the target camera.

It can be seen that in this example, when the camera application receives a notification message from the second thread, it does not need to turn on the camera. If it receives a notification message from the second thread, the target camera can be used directly, eliminating the need for the camera application This process of opening the camera.

In a possible example, before starting the first thread and starting the camera application through the first thread to display the camera preview interface, the method further includes: determining whether the application icon corresponding to the selection operation is all The application icon of the camera application; if so, it is determined whether the selection operation corresponds to opening the camera application and displaying the camera preview interface of the camera application.

Among them, before starting the two threads, it is known that the application to be started is the camera application. Therefore, in the process of starting the camera application, two threads are started. One thread is used to start the camera application, and the other thread is used to open the camera. Therefore, after starting the camera application, the application interface can be directly presented as the camera preview interface, because the camera is already turned on at this time.

For example, an embodiment of the present application provides a camera startup method that opens the camera device in advance, speeds up the startup time of the camera application, recognizes the camera click operation in advance, reads the camera to be opened, and starts the thread to complete the operation of opening the camera. When detecting that the user clicks on the camera application, the desktop sends the application intent that needs to be started to the Activity Manager Service (AMS), where AMS has functions such as managing Activity behavior, controlling the activity life cycle, dispatching message events, and memory management. The AMS process is actually the System Server process of the system service. It is just a service started by the system service. It runs in a thread of the system service. When the user clicks the application icon in the Launcher program, it will notify AMS to enable the main activity of the application. AMS parses the intent, reads the package name of the application to be opened, and identifies whether it is a camera application. If it is, AMS reads whether the camera application that needs to be opened has the permission to open the camera of the electronic device, if it is, AMS reads the camera that needs to be opened For example, the electronic device has a front camera and three rear cameras, so there are four camera IDs. AMS determines which camera of the electronic device needs to be opened based on the ID of the camera to be opened. After reading the camera’s identity, AMS starts the thread to perform the Camera open operation to open the camera, and after creating the Camera object, the Camera object is sent to another thread. At this time, in another thread, the opening has been executed. The camera application, the camera application will receive the Camera object that opened the camera, the camera application will first determine whether the passed Camera object is empty, if it is not, it means that the camera has been opened, and there is no need to execute the Camera open method, if it is, it means that If the camera is not opened successfully, the camera application needs to execute the opening of the camera.

It can be seen that, in this example, when it is determined that the application currently to be launched by the electronic device is a camera application, and the selection operation for the application is to open the camera application and display the camera preview interface, the camera operation and the camera application start are just opened. Parallel execution to improve the camera startup time, users do not need a long waiting time when opening the camera application, and can use the camera faster.

In a possible example, the selection operation is a touch operation on the touch display screen of the electronic device; the determining whether the application icon corresponding to the selection operation is the application icon of the camera application includes : Determine that the application icon of the camera application is in the target display area of the application desktop; when the selection operation is acquired, determine the touch area corresponding to the selection operation; when the touch area and the target are detected When the display area matches, it is determined that the application icon selected by the selection operation is the application icon of the camera application.

Among them, after obtaining the selection operation for multiple application icons on the application desktop, it is necessary to immediately determine whether the application to be started is a camera application, if it is, two threads need to be started, if not, no more Thread processing.

Wherein, when the selection operation for the application icon of the camera application on the desktop is detected, the electronic device first obtains the selection operation, and then determines the application icon of the camera application selected during the selection operation. Since the electronic device now has multiple camera applications, the target display area of these multiple camera applications on the application desktop can be determined first. Therefore, when the selection operation is obtained, the touch area corresponding to the selection operation can be immediately determined. It is determined whether the application icon selected by the selection operation is an application icon of a camera application, and there is no need for the desktop to determine the selected application through a series of processes such as obtaining the application identifier and analyzing the application identity.

It can be seen that in this example, by determining whether the touch area corresponding to the selected operation is the target display area of the application icon of the camera application on the application desktop, it can be quickly determined whether the application to be launched is a camera application, and thus, whether Multi-threaded processing is required.

In a possible example, the method further includes: when the camera application is in a video shooting scene or a video call scene, after exiting the application interface of the camera application, controlling the target camera to remain in an open state.

Among them, in general, after opening the camera application, the camera will be opened to present the camera preview interface. Since the camera is called by the camera application and controlled to open and close, the camera is closed after exiting the application interface, for example, during video During a call, if you quit the application interface of the currently open camera, the caller cannot see the face or sees the picture freezes, because the camera is actually turned off at this time. In this application, the camera is turned on and off by the system service. Therefore, even after exiting the application interface, the camera can be kept open, that is, the application can close the camera and the system service can also close the camera.

Among them, the application scene of the camera application is recognized. When it is detected that the camera application function is in the video shooting scene or the video call scene, it can be set so that after exiting the camera preview interface, or after the shooting interface, the camera can still be kept in In the open state, continue to record or shoot video.

It can be seen that in this example, under normal circumstances, the camera can be closed after exiting the application interface of the camera application. For special application scenarios such as video shooting scenes and video call scenes, the system service can control the opening and closing of the camera. In this type of scenario, after the front desk exits the application interface, you can continue to shoot and record the video without turning off the camera, thereby improving user experience.
