Description

Application management method and electronic device

Technical Field

The present application relates to the field of data processing, and more particularly, to a management method of an application program and an electronic device.

Background

At present, most Application programs (apps) support the functions of virtual screens. Wherein, the virtual screen refers to a virtual interface created and destroyed by the application. Wherein the interface of the virtual screen is typically not a display interface that is actually displayed by the electronic device.

It should be understood that, before each frame of image is sent and displayed by the electronic device in the process of displaying the display interface of the application program, image synthesis is required to be performed on the data to be displayed by a layer synthesis (surface eflinger) module, so as to obtain a synthesized image, and then the synthesized image is sent to the display screen to be displayed. If the application program creates the virtual screen, the surfeflinger module also needs to perform image layer combination processing on the data to be displayed corresponding to the virtual screen to obtain a synthesized image, then the synthesized image is sent to the application program, and the application program determines the purpose of the synthesized image. For example, the application may send the synthesized image to the projection device to cause the projection device to display the synthesized image. Alternatively, the application may encode the synthesized image, generate a file in video format, and store the file. However, when an application program that creates a virtual screen is turned into background operation, the electronic device typically performs interrupt processing on a thread corresponding to the application program to reduce the CPU load. In this case, since the application program creates the virtual screen, the system process in the electronic device still needs to interact with the application program frequently, which may cause a problem in the system process, and further cause a problem in that the electronic device is turned on or turned off.

Based on this, how to avoid the problem of black screen or restarting of the electronic device when the application program that creates the virtual screen is turned into the background running becomes a problem to be solved.

Thus, a feature defining "a first", "a second", or a third "may explicitly or implicitly include one or more such feature.

For ease of understanding, the description of the concepts related to the embodiments of the present application is given in part by way of example for reference.

1. Virtual screen

A virtual screen may refer to a virtually displayed interface that is created and destroyed by an application in an electronic device. The virtual screen may be the same as or different from the interface content displayed by the electronic device, which is not limited in the embodiments of the present application.

It should be appreciated that prior to displaying the interface on the display screen, the electronic device typically performs a layer composition process on the content to be displayed through a layer composition (surfeflinger) module, and then sends the composite image to the display screen for display. Similarly, after the application program creates the virtual screen, the image layer of the virtual screen is also subjected to image layer combination processing, so as to obtain a combined image, namely an interface of the virtual screen. However, the interface of the virtual screen is not usually displayed, and the application program may store the interface of the virtual screen as a video file or an image file, or may send the interface of the virtual screen to the screen-throwing device, so that the screen-throwing device displays the interface of the virtual screen.

The screen recording program for recording the screen can create a virtual screen based on the currently displayed interface, copy the currently displayed interface to obtain the interface of the virtual screen, and store the interface of the virtual screen as a video file to realize the recording function of the current interface.

2. Application freezing

In order to reduce the load of the central processing unit (central processing unit, CPU), the electronic device may interrupt the process of the application program when the application program is in a state not perceived by the user, so as to reduce the load of the CPU and further reduce the power consumption of the electronic device. The state in which the electronic device interrupts the progress of an application while the application is not perceived by the user is referred to as freezing of the application. Wherein, the application program not being perceived by the user may mean that the application program does not output information outwards, so that the user cannot perceive that the application program is in a working state, and specifically may include: the application does not output an audio signal, a video signal, or the application does not control the electronic device to vibrate, or the application does not download data, or the application does not output navigation information to the user.

At present, an application program acquires related data of a frame image to be displayed, and the related data of the frame image to be displayed is processed according to a fixed flow and is sent to a display screen for display. The fixed flow mainly comprises a drawing and rendering flow, a diagram layer synthesizing flow and a sending and displaying flow. That is, for a certain frame of image, the electronic device needs to sequentially execute a drawing rendering process, a diagram layer synthesizing process and a sending process before displaying the image on the display screen. The layer composition process may be implemented by a layer composition (surfeflinger) module.

It should be understood that in the case where the application program creates a virtual screen, a drawing rendering flow, a diagram layer composition flow, and a send-display flow are performed once for the relevant data displayed on the display screen. For the related data of the virtual screen, a drawing rendering flow and a diagram synthesizing flow are executed, the synthesized image is not executed to be sent to the displaying flow, and the application program generally determines the purpose of the synthesized image.

For example, the application may send the synthesized image to the projection device to cause the projection device to display the synthesized image. Alternatively, the application may encode the synthesized image, generate a file in video format, and store the file. However, when the application program with the virtual screen created is in a state not perceived by the user (for example, the application program is turned into background running), the electronic device generally performs interrupt processing on a thread corresponding to the application program, so as to reduce the load of the CPU, and further reduce the power consumption of the electronic device. In this case, since the application program creates the virtual screen, the system process in the electronic device still needs to interact with the application program frequently, which may cause a problem in the system process, and thus cause a problem in the electronic device of blacking out or restarting.

In view of this, the embodiment of the application provides a management method of an application program, which is applied to an electronic device, and includes determining whether a first application program creates a virtual screen, if the first application program creates the virtual screen, stopping performing layer composition processing on an image of the virtual screen when the electronic device is in a first state, and then performing first processing on the first application program, where the first state refers to that the electronic device stops outputting first information through the first application program, the type of the first information includes audio, picture, video and/or vibration, the first processing refers to a process of interrupting a process of the first application program, when the electronic device stops outputting information of an audio type, a picture type, a video type and/or vibration type through the first application program, which is equivalent to a state that the first application program is not perceived by a user, in this case, the electronic device stops performing layer composition processing on the image of the virtual screen first application program, and then interrupts the process of the first application program, so that after the process of the first application program is interrupted, a problem that a system frequently interacts with the first application program due to the layer composition processing on the image of the virtual screen is also performed, and a system frequently interacts with the first application program is avoided, and a problem that the system frequently interacts with the first application program is frequently caused by restarting the system, and the system is avoided.

Optionally, the electronic device includes a terminal device, which may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and so on.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present application.

The layered architecture of the electronic device 100 divides the software into several layers, each with a distinct role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, power saving demons, etc.

Wherein the power saving puck may be used to manage individual applications.

For example, when the "map" application is shifted to background operation, the power saving puck may interrupt the process of the "map" application to reduce the load of the CPU and thus reduce the power consumption of the electronic device.

The display manager may be used to determine whether the application program created a virtual screen.

The SurfaceFlinger module is configured to execute a layer composition flow upon receiving a layer composition trigger signal.

For example, the surfeflinger module may execute a layer composition flow upon receiving a layer composition trigger signal, generating an image of an interface displayed on a physical screen.

For another example, the surfeflinger module may execute a layer composition flow upon receiving a layer composition trigger signal to generate an image at an interface of the virtual screen.

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

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

Fig. 3 is an application scenario schematic diagram of a method for managing an application program according to an embodiment of the present application. As shown in fig. 3 (a), the user clicks on the application program "screen recording" 10, and the application program that the mobile phone starts to run is "screen recording". In order to allow a user to more intuitively view the recorded interface, a "screen recording" typically creates a virtual screen so that the user can observe the recorded content. The user then slides up as shown in fig. 3 (b). Responding to the sliding operation of the user, the mobile phone displays a display interface of the application program 'video playing', and starts recording the current interface through 'screen recording'. At this time, the interface being displayed is the interface of "video play", but it corresponds to the virtual screen created by "screen recording", and "screen recording" goes into background operation, as shown in (c) of fig. 3. Wherein, compared with the interface of video playing, the control 20 and the control 30 for indicating that the screen is being recorded are added on the display interface of the virtual screen created by the screen recording. In this case, since the "screen recording" creates the virtual screen, when the "screen recording" is shifted to the background operation, the system process in the electronic device may then frequently perform data interaction with the virtual screen, which may cause the electronic device to be in a black screen or dead state, as shown in (d) of fig. 3. The application program management method provided by the embodiment of the application program can avoid the situation.

It should be understood that the foregoing is illustrative of an application scenario, and is not intended to limit the application scenario of the present application in any way.

The following describes in detail the management method of the application program provided in the embodiment of the present application with reference to fig. 4 to 7.

Fig. 4 is a flowchart of a method for managing an application program according to an embodiment of the present application, as shown in fig. 4, where the method includes:

s101, determining whether a first application program creates a virtual screen.

The first application may be an application in the electronic device capable of creating a virtual screen. For example, the first application may be "screen recording" or "haro bicycle ^TM ", can also be" glory VR ^TM By way of example, the present application is not limited in this regard.

If the first application creates a virtual screen, S102 is performed.

S102, stopping performing layer combination processing on the image of the virtual screen when the electronic equipment is in the first state.

The first state refers to that the electronic device stops outputting first information through the first application program, and the type of the first information comprises audio, pictures, video and/or vibration. Since the electronic device stops outputting the audio, picture, video and/or vibration type information through the first application, the user cannot perceive the first application. That is, the first application cannot be perceived by the user while the electronic device is in the first state.

For example, when the electronic device is in the off-screen state, the first application cannot output audio, picture, video, and/or vibration type information, and thus the first application cannot be perceived by the user. That is, the electronic device being in the first state may mean that the electronic device is in a state of off-screen.

For another example, a first application in the electronic device transitions to background operation, and the first application cannot output audio, picture, video, and/or vibration type information, and thus the first application cannot be perceived by the user. That is, the electronic device being in the first state may refer to a state in which a first application in the electronic device is running in the background.

When the electronic device is in the first state, the electronic device may interrupt a process of performing layer composition processing on the image of the virtual screen, so that the electronic device stops performing layer composition processing on the image of the virtual screen. Because the electronic device interrupts the process of performing the layer composition processing on the image of the virtual screen, the system process of the electronic device does not perform frequent data interaction between the process of the virtual screen and the first application program.

S103, performing first processing on the first application program.

Wherein the first process refers to a process of interrupting a process of the first application program.

It should be appreciated that interrupting the process of the first application corresponds to freezing the first application. According to the application program management method provided by the embodiment of the application program, when the first application program in the electronic device is not perceived by a user, the electronic device stops performing layer combination processing on the image of the virtual screen created by the first application program, and then freezes the first application program.

In one possible scenario, when the first application program is converted from a state that is not perceived by the user to a state that is perceived by the user, that is, when the first application program is converted from the first state to the second state, the electronic device resumes the process of the first application program after performing the layer composition processing on the image of the virtual screen. The second state may be a state in which the second application requests communication with the first application, may be a state in which the first application is changed from background operation to foreground operation, or may be a state in which the electronic device is changed from off-screen to on-screen. This is explained in detail below by way of the embodiment shown in fig. 5.

Fig. 5 is a flowchart of a method for managing an application program according to another embodiment provided in the present application, as shown in fig. 5, where the method includes:

s201, determining whether a virtual screen is created by the first application program.

If the first application creates a virtual screen, S102 is performed.

And S202, stopping performing layer combination processing on the image of the virtual screen when the electronic equipment is in the first state.

The first state refers to that the electronic device stops outputting first information through the first application program, and the type of the first information comprises audio, pictures, video and/or vibration.

S203, performing first processing on the first application program, wherein the first processing refers to processing of interrupting the process of the first application program.

S204, when the electronic equipment is converted from the first state to the second state, the image layer combination processing is carried out on the image of the virtual screen.

The second state refers to a state that the electronic device resumes outputting the first information through the first application program. It should be appreciated that the type of first information may include audio, picture, video, and/or vibration, and when the electronic device resumes outputting the audio, picture, video, and/or vibration type of information through the first application, the user may perceive the information output by the first application, i.e., the first application may be perceived by the user. When the first application program is converted from a state (first state) which is not perceived by the user to a state (second state) which can be perceived by the user, the electronic device can perform layer composition processing on the image of the virtual screen, namely, a process of recovering the virtual screen.

Optionally, the second state includes a state in which the second application requests communication with the first application.

It should be understood that the second application may refer to other applications in the electronic device than the first application. When a second application requests communication to be established with a first application, it is often necessary to wake up the first application from a frozen state, i.e. to resume the process of the first application. According to the application program management method, before the first application program is awakened, image layer combination processing is conducted on the images of the virtual screen.

Optionally, the second state includes a state in which the first application transitions from background running to foreground running.

When the first application program runs in the background, the first application program usually does not output information and is in a state of being not perceived by a user; when the first application program runs in the foreground, the first application program starts to output information and is in a state of being perceived by a user. Therefore, when the first application program is changed from the background running to the foreground running, the first application program needs to be awakened from the frozen state to the normal state, that is, the process of the first application program needs to be restored. According to the application program management method, before the first application program is awakened, image layer combination processing is conducted on the images of the virtual screen.

Optionally, the second state includes a state in which the electronic device transitions from off-screen to on-screen.

Typically, when the electronic device is off-screen, the first application program will not normally output information, and is in a state of being not perceived by the user; when the electronic equipment is changed from off screen to on screen, the first application program starts to output information and is in a state perceived by a user. Therefore, when the electronic device changes from the off-screen state to the on-screen state, the first application program is usually required to be awakened from the frozen state to the normal state, that is, the process of the first application program needs to be restored. According to the application program management method, before the first application program is awakened, image layer combination processing is conducted on the images of the virtual screen.

S205, performing a second process on the first application program, where the second process is a process for recovering the process of the first application program.

It should be appreciated that restoring the process of the first application corresponds to thawing the first application. According to the application program management method provided by the embodiment of the application program, when the first application program in the electronic equipment is converted from a state not perceived by a user to a state perceived by the user, the electronic equipment firstly resumes the image of the virtual screen created by the first application program to carry out image layer combination processing, and then unfreezes the first application program.

In one possible scenario, the electronic device includes an application program (corresponding to a third application program) of a "power saving eidolon", where the "power saving eidolon" can interrupt the process of other application programs (e.g., the first application program) when the other application programs are transferred to the background running, so as to reduce the power consumption of the electronic device. It should be understood that, in an electronic device to which the application program management method provided in the embodiment of the present application is applied, a software framework of the electronic device may be shown in fig. 2, where the software framework includes a first application program, a second application program, an application program "power saving eidolon", an image synthesis SurfaceFlinger module, a display manager, and a window manager. This is explained in detail below with reference to fig. 6 and 7.

Fig. 6 is a flowchart of a method for managing an application program, where the method is applied to an electronic device, and the electronic device includes a first application program, a second application program, an application program "power saving eidolon", an image synthesis SurfaceFlinger module, a display manager, and a window manager, as shown in fig. 6, and the method includes:

s301, the display manager determines whether the first application program creates a virtual screen.

If the first application creates a virtual screen, S302 is performed.

It should be appreciated that the Display Manager may be used to determine whether the application created a virtual screen. For example. The displaymanager may confirm whether the first application created the virtual screen based on whether the first application invoked the "create Virtual Display" function. If the Display Manager determines that the first application program calls the create Virtual Display function, the first application program creates a virtual screen; if the Display Manager determines that the first application does not call the "create Virtual Display" function, the first application does not create a virtual screen.

S302, the window manager determines whether the electronic device is in a first state.

If the electronic device is in the first state, S303 is executed.

It should be appreciated that when the window manager determines that the electronic device is in the first state, the window manager may send information to the "power saving puck" indicating that the electronic device is in the first state, such that the "power saving puck" performs the corresponding method steps based on the state of the electronic device.

S303, sending a first instruction to a SurfaceFlinger module by the power saving eidolon.

The first instruction may be an instruction instructing the surfeflinger module to stop performing layer composition processing on the image of the virtual screen.

"Power saving puck" may refer to an application in an electronic device for managing an application, i.e., a third application. The power saving eidolon can interrupt a process related to the first application program when the first application program is in a frozen state, so that the load of a processor of the electronic device is reduced, and the power consumption of the electronic device is further reduced. The "power saving sprite" may also resume processes associated with the first application when the first application is awakened from a frozen state, so that the first application may function properly.

It should be appreciated that when the window manager determines that the electronic device is in the first state, the window manager may send information to the "power saving puck" indicating that the electronic device is in the first state, and after the "power saving puck" receives the information, send a first instruction to the SurfaceFlinger module.

S304, responding to the first instruction by the SurfaceFlinger module, and stopping performing layer composition processing on the image of the virtual screen.

It should be appreciated that the SurfaceFlinger module stops the layer composition process on the image of the virtual screen in response to the first instruction, which is equivalent to the SurfaceFlinger module interrupting the progress of the layer composition process on the image of the virtual screen.

S305, "power saving puck" sends a second instruction to the first application.

Wherein the second instruction is for indicating a process of interrupting the first application.

After the "power saving puck" sends the first instruction to the SurfaceFlinger module, the "power saving puck" sends a second instruction to the first application indicating to interrupt the process of the first application. That is, the "power saving puck" may first send a first instruction that instructs the surfeflinger module to stop layer composition processing of the image of the virtual screen, and then send a second instruction that instructs to interrupt the process of the first application.

S306, the first application program responds to the second instruction, and the process of the first application program is interrupted.

The method comprises the steps that whether the first application program creates a virtual screen or not is determined by a Display Manager, the window Manager determines whether the electronic device is in a first state or not under the condition that the first application program creates the virtual screen, and further when the electronic device is in the first state, a first instruction for indicating stopping image layer composition processing of an image of the virtual screen is sent to the Surfacefringer module through the power saving agent, then a second instruction for indicating interrupting the process of the first application program is sent to the first application program through the power saving agent, and as the image layer composition processing of the virtual screen is stopped before interrupting the process of the first application program, the problem that the system frequently interacts with the first application program due to the fact that the first application program continues image layer composition processing of the virtual screen is carried out on the first application program is avoided, and the problem that the system frequently interacts with the first application program due to the fact that the system frequently interacts with the first application program is frequently restarted is avoided.

S307, the window manager determines whether the first application program is changed from the background operation to the foreground operation.

It should be appreciated that a window manager may be used to manage a window program. The window manager may obtain the size of the display screen, determine whether there is a status bar, lock the screen, intercept the screen, etc., to determine whether the first application is to be run from the background to the foreground according to the display content on the current display interface. Typically, the first application begins to be perceived by the user when the first application transitions from background running to foreground running.

If the first application program is changed from the background operation to the foreground operation, S311 is executed.

It should be appreciated that when the window manager determines that the first application is going from background to foreground, the window manager may send a message to the "power saving puck" indicating that the electronic device is going from off-screen to on-screen, so that the "power saving puck" performs the method steps of S311.

S308, the window manager determines whether a first operation of the user is detected.

The first operation may refer to an operation of switching the electronic device from off-screen to on-screen.

It should be appreciated that a window manager may be used to manage a window program. The window manager may obtain the size of the display screen, determine whether there is a status bar, lock the screen, intercept the screen, etc., to determine whether the electronic device transitions from off-screen to on-screen according to the display content on the current display interface. Typically, when an electronic device transitions from off-screen to on-screen, a first application running in the foreground in the electronic device begins to be perceived by the user.

If the first operation of the user is detected, S311 is performed.

It should be appreciated that when the window manager determines that the electronic device transitions from off-screen to on-screen, the window manager may send information to the "power saving puck" indicating that the electronic device transitions from off-screen to on-screen, to cause the "power saving puck" to perform the method steps of S311.

S309, the second application program sends a first request to the "power saving puck".

Wherein the first request is for indicating that the second application requests to establish communication with the first application.

It should be understood that the second application may refer to other applications in the electronic device than the first application. When the first application program is in a frozen state, the second application program needs to communicate with the first application program, and a first request for indicating the second application program to request to establish communication with the first application program needs to be sent to the power-saving eidolon.

S310, a "power saving puck" performs S311 in response to the first request.

S311, the "power saving eidolon" sends a third instruction to the SurfaceFlinger module.

The third instruction is used for indicating the SurfaceFlinger module to resume the image composition processing of the virtual screen.

S312, responding to the third instruction by the SurfaceFlinger module, and recovering to perform layer composition processing on the image of the virtual screen.

Since the SurfaceFlinger module stops the layer composition process on the image of the virtual screen when the first application is in the frozen state. Therefore, when the power-saving eidolon sends a third instruction to the surfeflinger module, the surfeflinger module resumes the graphics layer composition processing of the image of the virtual screen.

It should be understood that, the "power saving eidolon" sends the third instruction to the surfacef linger module is sent when the window manager determines that the first application program is changed from the background operation to the foreground operation, or the window manager determines that the first operation of the user is detected, or the second application program sends the first request to the "power saving eidolon", which corresponds to that when the window manager determines that the first application program is changed from the background operation to the foreground operation, the surfacef linger module resumes the image layer composition processing of the image of the virtual screen, or when the window manager determines that the first operation of the user is detected, the surfacef linger module resumes the image layer composition processing of the virtual screen, or when the second application program sends the first request to the "power saving eidolon", the surfacef linger module resumes the image layer composition processing of the image of the virtual screen.

S313, "power saving puck" sends a fourth instruction to the first application.

The fourth instruction is used for indicating a process for recovering the first application program.

S314, the first application program responds to the fourth instruction, and the process of the first application program is restored.

It should be appreciated that restoring the process of the first application corresponds to thawing the first application. According to the application program management method provided by the embodiment of the application program, when the first application program in the electronic equipment is converted from a state not perceived by a user to a state perceived by the user, the surfeflinger module resumes image layer combination processing on the image of the virtual screen, and then resumes the progress of the first application program.

For example, when the window manager determines that the first application is changed from the background operation to the foreground operation, the SurfaceFlinger module resumes the image composition processing on the image of the virtual screen, and then resumes the process of the first application.

For another example, the window manager determines that when the first operation of switching the electronic device from off-screen to on-screen is detected by the user, the surfeflinger module resumes performing layer composition processing on the image of the virtual screen, and then resumes the process of the first application.

For another example, when the second application sends a first request to the "power saving wizard" to request communication with the first application, the SurfaceFlinger module resumes the graphics layer processing of the image of the virtual screen, and then resumes the process of the first application.

The application program management method provided by the embodiment of the application program is applied to electronic equipment, the electronic equipment comprises a first application program, a second application program, an application program electricity-saving eidolon, an image synthesis SurfaceFlinger module, a display manager and a window manager, in the process of thawing the first application program, the window manager determines that the first application program is changed from background operation to front operation, or the window manager determines that the electronic equipment is changed from off screen to on screen operation, or the second application program requests to establish communication connection with the first application program, the electricity-saving eidolon sends an instruction for instructing the SurfaceFlinger module to resume image layer composition processing of the virtual screen to the first application program, and then sends an instruction for resuming the process of the first application program to the first application program, so that before thawing the first application program, the image of the virtual screen is subjected to image layer composition processing, namely, when the first application program is thawed, the electronic equipment can acquire the image of the virtual screen, or the second application program requests to establish communication connection with the first application program, and the problem of real-time image thawing of the virtual screen is avoided.

In one possible scenario, where the first application does not create a virtual screen, the "power saving puck" may directly freeze the first application without the first application being perceived by the user, reducing power consumption of the electronic device, as described in detail below with respect to FIG. 7.

S407, the window manager determines whether the first application program is changed from the background operation to the foreground operation.

If the first application is changed from the background operation to the foreground operation, S411 is executed.

It should be appreciated that when the window manager determines that the first application is going from background to foreground, the window manager may send a message to the "power saving puck" indicating that the electronic device is going from off-screen to on-screen, so that the "power saving puck" performs the method steps of S411.

If the window manager determines that the electronic device is in the second state, S421 is performed.

S421, the "power saving puck" sends a sixth instruction to the first application.

The sixth instruction is used for indicating a process of recovering the first application program.

S422, the first application program responds to the sixth instruction, and the process of the first application program is restored.

According to the application program management method, a third application program ('electricity-saving eidolon') can not only stop image layer combination processing on an image of a virtual screen under the condition that the virtual screen is created by a first application program, but also interrupt the process of the first application program so as to avoid the problem of system breakdown caused by frequent interaction between the system process and the first application program when the first application program is in a frozen state; and under the condition that the first application program does not create the virtual screen, the process of the first application program is directly interrupted, so that the power consumption of the electronic equipment is reduced.
