Description
Technical Field
The present invention relates to the technical field of application programs, and in particular, to a method and an apparatus for switching an application program, an electronic device, and a computer-readable storage medium.
Background
When an application enters the background, the system will strive to keep more applications running in the background at the same time (suspended state rather than terminated). However, when the system memory is insufficient (each application program occupies the system memory when running), some suspended application programs are terminated to recycle the memory; generally, the program with the largest memory is terminated preferentially.
The video of the application program in the online audio and video interaction classroom is an important function in the teaching interaction process, and the application program needs to start video rendering when running in the foreground; in some operating systems, however, rendering using a rendering interface is required. For example, in the apple IOS system, the OpenGL ES interface needs to be invoked to render video. OpenGL ES is a subset of OpenGL (Open Graphics Library, an application programming interface for rendering Graphics, which can efficiently implement Graphics rendering), and can efficiently implement an application programming interface for video rendering.
Before the application program enters the background, the resources of OpenGL need to be released, so that the program in the background can use more resources. When the foreground application is switched to the background (for example, a Home key of the device is pressed), if the application still calls a rendering interface (for example, an interface provided by OpenGL), the application running in the background is forcibly terminated. To avoid this problem, the rendering interface is typically stopped from being invoked when switching to the background, so that the application can be suspended in the background and can continue to run normally when switching to the foreground again. However, the above scheme still occasionally causes the application to crash when the application is switched to the background.

Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
Fig. 1 shows a flowchart of a method for switching an application according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step 101: and calling a rendering interface in the process of performing video rendering on the application program operated in the foreground, and playing the rendered video frame based on the rendering view.
In the embodiment of the invention, the application program is an application program which is installed at a mobile terminal and needs to render a video, and for example, the application program can be an application program installed on an iphone or an ipad; moreover, the application program needs to call a corresponding rendering interface in the rendering process, such as a rendering start interface provided by OpenGL ES, and the application program can acquire the rendered video frame by calling the rendering interface, and then play the video frame. In the embodiment of the invention, a rendering view is set for an application program, and the rendering view is used for playing rendered video frames. Specifically, the application program can be a live application program or a video-capable application program, the application program can acquire data to be rendered when the foreground runs and needs to play a video, the data is rendered by calling a rendering interface, and then a rendered video frame is generated, and the rendered video frame can be played through the rendering view, so that a user can view the rendered video frame.
Optionally, the step of "invoking rendering interface" specifically includes:
step A1: starting a rendering timer, calling a corresponding rendering interface, and performing rendering processing based on the rendering timer; the rendering timer is a timer determined according to the screen refresh frequency.
In the embodiment of the invention, a corresponding timer, namely a rendering timer, is determined according to the screen refresh frequency of the device where the application program is located, and generally, the rendering timer is kept consistent with the screen refresh frequency. For example, the screen refresh frequency is 60 frames, i.e. 60 pictures (video frames) are displayed every second, and the rendering timer will perform the action of rendering pictures every 1/60 seconds; therefore, the video frame rate and the screen refreshing frequency can be kept consistent, and the video looks smoother.
Step 102: and when a first switching instruction for switching from a foreground to a background is received, calling a rendering stopping interface, and cleaning a memory used in the video rendering process.
In the embodiment of the present invention, when an application program is switched from a foreground to a background (or from the background to the foreground), for example, when a user presses a Home key, an operating system sends a corresponding notification, and this embodiment may determine whether a corresponding switching instruction is received by monitoring the notification; for example, when it is monitored that the application program switches from the foreground to the background, it may be determined that a corresponding first switching instruction is received. The first switching instruction is used for indicating the state of the switching application program, namely switching from the foreground to the background.
In the embodiment of the present invention, when the first switching instruction is received, a rendering stopping interface is invoked, for example, a deletedaway interface provided by an operating system is invoked, so that the operating system can invoke a relevant interface of an OpenGL ES, and thus rendering can be stopped, and other interfaces of the OpenGL ES are no longer invoked. And corresponding memories can be allocated for use in the rendering process, and are cleaned when the rendering process is switched to the background.
Further optionally, the method may further comprise:
step B1: and when a first switching instruction for switching from the foreground to the background is received, stopping acquiring the data to be rendered and stopping the rendering timer.
In the embodiment of the present invention, as shown in the step a1, if the rendering timer is started during rendering, the rendering timer also needs to be stopped when rendering needs to be stopped.
Step 103: the rendered view is removed, and the application is then switched to run in the background.
As described above, although the conventional scheme stops calling the rendering interface when switching to the background, there is still an occasional crash, i.e., the application program may crash by chance. In completing the creation of the present invention, the inventors found that this is caused by a time difference between rendering the video and stopping the rendering. Specifically, rendering the video and stopping rendering are performed by different threads. After a polling timer (i.e., a rendering timer) is started, after video data is received, a rendering interface is called through a thread A to achieve video rendering, and meanwhile, the video data is transmitted to achieve video rendering. When the background is switched, rendering is stopped through other threads B, namely, a rendering stopping interface is called, and a corresponding memory is cleared; specifically, when the background is switched, the polling timer is stopped, so that the thread A is not informed to call a rendering interface and transmit video data; the deletedaway interface is invoked, the buffered objects associated with the rendered view are deleted, and the associated object memory is cleared. At this time, when the thread B calls the rendering stopping interface, the thread a is still executing, and before the thread B calls the deletedwable clearing buffer, the thread a has taken out one frame of video data from the buffer, and then starts to call the rendering interface and starts to perform rendering operation on the video data. At this time, even if the rendering stopping interface is called, the application still calls the API of OpenGL in the background to render and play the video, and the system prohibits the application in the background from calling the command of OpenGL, so that the application is forcibly terminated, and the application crashes.
In the embodiment of the present invention, rendering is stopped, and the rendering view used for playing the rendered video frame is also removed, so that even if there is a video frame that has not been rendered at the time point when rendering is stopped, the association with OpenGL can be completely broken because there is no rendering view for playing the rendered video frame, and the application program will not be affected by the video frame that has not been rendered. And then, the application program is switched to the background operation, so that the application program running in the background is not influenced by the video frames which are not rendered, and the accidental collapse can be avoided.
Further optionally, if the application running in the background is not terminated due to too many background running programs, it may switch to the foreground running normally. Specifically, the method may further include:
step C1: and when a second switching instruction for switching from the background to the foreground is received, switching the application program to the foreground for running, then recreating the rendering view, acquiring the data to be rendered, and recalling the rendering interface.
In the embodiment of the invention, when a second switching instruction for switching the application program running in the background to the foreground is received, the application program is switched to the foreground to run, then the rendering view is created again, and the rendering interface is called again; in addition, the rendering timer described above may also be restarted. When a second switching instruction is received, the application program is preferentially switched to the foreground, so that the application program is not crashed even if the rendering view is created subsequently. When data to be rendered are acquired, rendering processing can be performed according to the step 101, and the rendered video frames are played through the rendering view for a user to watch.
According to the method for switching the application program, provided by the embodiment of the invention, the application program running in the foreground plays the rendered video frame through the rendering view, the rendering stopping interface is called to stop rendering when the application program needs to be switched to the background, and the rendering view is removed, so that the video frame which is not rendered can not influence the switching of the application program to the background, the application program can not be subjected to occasional collapse when being switched to the background, and the robustness and the stability of the application program can be improved.
On the basis of the above embodiment, the rendered view is removed when switching to the background, and at this time, the application program does not play any video frame, and the user sees a black screen, that is, there is a problem of a black screen at a moment. In the embodiment of the present invention, the problem is avoided by displaying the target image, and specifically, the method further includes:
step D1: when a first switching instruction for switching from a foreground to a background is received, converting a currently rendered video frame into a target image, and displaying the target image at a position corresponding to a rendering view.
Step D2: upon receiving a second switch instruction for switching from the background to the foreground, the target image is removed after the rendered view is recreated and the rendering interface is recalled.
In the embodiment of the invention, when a first switching instruction is received, before the rendering view is removed, the last frame of rendering is converted into the target image, and the target image is displayed at the position corresponding to the rendering view, so that the target image can cover the rendering view. And then, even if the rendering view is removed, the user can see the target image, so that the problem of black screen does not occur in the process of switching the application program to the background.
In addition, when the application program returns to the foreground operation again, after the rendering view is created again and the rendering interface is called again, the rendered video frame can be generated and played normally, at the moment, the target image is removed, so that the application program switched to the foreground can operate normally, and the target image cannot shield the video frame.
The method flow of switching the application program is described in detail below by an embodiment. Referring to fig. 2, the method includes:
step 201: the application program runs in the foreground, and a rendering view is created; starting a rendering timer, calling a rendering interface, converting the acquired data into rendered video frames, and playing the rendered video frames based on the rendering view.
Step 202: when a first switching instruction for switching from a foreground to a background is received, converting a currently rendered latest video frame into a target image, and displaying the target image at a position corresponding to a rendering view.
Step 203: stopping receiving data to be rendered, stopping the rendering timer, calling a rendering stopping interface, cleaning a memory used in the video rendering process, and removing the rendering view.
In the embodiment of the present invention, when the first switching instruction is received, the rendered view needs to be removed after the target image is displayed, and the rest of the processes may be performed simultaneously, that is, after the target image is generated, the above steps 202 and 203 may be performed simultaneously.
Step 204: and then the application program is switched to the background to run, and a target image is reserved.
Step 205: and under the condition that the application program is not terminated, switching the application program to the foreground to run when a second switching instruction for switching from the background to the foreground is received.
Step 206: and then, recreating the rendering view, starting a rendering timer, acquiring data needing rendering, recalling a rendering interface, and then removing the target image.
According to the method for switching the application program, provided by the embodiment of the invention, the application program running in the foreground plays the rendered video frame through the rendering view, the rendering stopping interface is called to stop rendering when the application program needs to be switched to the background, and the rendering view is removed, so that the video frame which is not rendered can not influence the switching of the application program to the background, the application program can not be subjected to occasional collapse when being switched to the background, and the robustness and the stability of the application program can be improved. When switching to the background, the target image is generated based on the video frame of the last frame and displayed on the upper layer of the rendered view, so that the problem of black screen is not caused when the rendered view is removed.
The method for switching the application program provided by the embodiment of the present invention is described above in detail, and the method may also be implemented by a corresponding apparatus.
