3 is a flow chart of an application processing method in one embodiment. The application processing method in this embodiment is described by using the terminal or server running in FIG. 1 as an example. As shown in FIG. 3, the application processing method includes operations 302 through 308. among them:

Operation 302, when the electronic device outputs a continuous image frame, acquires the number of lost frames of the image frame.

An application (Application) refers to a software written for an application purpose in an electronic device, and the electronic device can implement a service demanded by the user through an application. For example, users can play games through a game-like application, watch videos through a video-like application, and play music through a music-like application. Applications can be divided into foreground applications and background applications based on the state of the run. The foreground application refers to an application running in the foreground of the electronic device, and the foreground application can be displayed and interacted with the user in the foreground. A background application refers to an application that runs in the background of an electronic device. The background application generally cannot display and interact with the user in the foreground.

Generally, the application operation of the application is completed by one or more processes. The process is a running activity of the program in the computer on a certain data set, and is a basic unit for the system to perform resource allocation and scheduling. At the same time, a process can correspond to one or more threads. A thread is a single sequential control process in a program, and is a relatively independent, schedulable execution unit within a process. The process may include a foreground process and a background process, and the foreground process is a process running in the foreground of the electronic device, and the background process is a process running in the background of the electronic device. The electronic device can control the switching between the foreground process and the background process, and the foreground process can switch to the background operation, and the background process can also switch to the foreground operation. Specifically, the process can be managed by the process pool, and the process identifier corresponding to one or more processes can be stored in the process pool. The process ID is used to uniquely identify a process. The process pool may include a foreground process pool and a background process pool. The foreground process pool includes a process identifier corresponding to the foreground process, and the background process pool includes a process identifier corresponding to the background process. When it is detected that the running status of the foreground process and the background process changes, the process pool will add or delete the process ID that changes accordingly. For example, the process ID of process A is “0123”. When it is detected that process A changes from the background process to the foreground process, the process ID “0123” of process A can be removed from the background process pool and added to the foreground process. In the pool.

When the foreground application is running, the files of the foreground application are displayed on the output device of the electronic device, and the user can interact with the electronic device through the input device and the output device. For example, an electronic device can display an image in an output device while playing video or entering a game interface. In order to reflect the continuity of playback, a continuous sequence of image frames is often played in the output device, and the images in the sequence of image frames form a continuous animation. By playing the sequence of image frames at regular intervals, a continuous animation interface is formed, wherein each image in the sequence of image frames can be referred to as an image frame. When the foreground application displays a sequence of consecutive image frames in the output device, it plays timing and plays each image frame in the order of the sequence of image frames. Therefore, under normal circumstances, a fixed number of image frames will be played for a certain period of time. If the number of image frames played during a certain period of time is less than the predetermined number, it means that the playback is abnormal. The number of lost frames is the number of image frames lost by the electronic device when outputting consecutive image frames. For example, if the number of consecutive image frames to be played is 10 frames, and only 7 frames are actually played, the number of lost frames of the image frame is 3 frames.

Operation 304, obtaining a Karton level of the foreground application according to the number of lost frames.

When the foreground application outputs a continuous image frame through an electronic device, the occupancy rate of the outputted continuous frame image is generally lost due to the high occupancy rate of resources such as the network of the electronic device and the CPU (Central Processing Unit). When a continuous image frame of the playback is lost, it can be determined that the operation of the foreground application in the electronic device has caused a jam. The Carton level is the severity of the front-end application jam. The more frames that are lost in the image frame, the more the foreground application is stuck and the higher the card level. Corresponding relationship between the number of lost frames and the Karton level is established in advance, and then the corresponding card level is obtained according to the obtained number of lost frames. For example, the Carton level can be divided into a heavy card, a normal card, and a light carton. Assuming that the continuous image frame includes a total of 20 frames, the correspondence between the number of lost frames and the Karton level can be established. When the number of lost frames is [0, 5], [5, 15], [15, 20], it corresponds to three levels of light, such as light, common, and heavy.

Operation 306, obtaining a to-be-processed application from the background application according to the foreground application, and obtaining a resource restriction policy according to the Karton level.

A pending application is an application that requires resource throttling. It can be understood that the application running in the electronic device can be divided into a foreground application and a background application. When the current application generates a jam, the resources of the electronic device are relatively tight. The resources occupied by the background application can be controlled to use more resources in the electronic device for the running of the foreground application. The obtaining the to-be-processed application may include: obtaining a foreground application priority of the foreground application; and acquiring a background application whose application priority is lower than the foreground application priority, as the to-be-processed application. Application priority is used to indicate the importance of the application. For example, the application priority of the system application can be defined to be higher than the application priority of the third-party application, or the application priority can be defined according to the type of the application, and the application priority of the instant messaging application is higher than that of the game application. The user or the system can customize the application priority, which is not specifically limited in this embodiment.

The resource restriction policy refers to a policy for processing resource restriction processing on an application, pre-establishes a correspondence between a card level and a resource restriction policy, and then acquires a corresponding resource restriction policy according to the card level. For example, when the Karton level is severely stuck, the application to be processed is frozen; when the Karton level is lightly stuck, the resources occupied by the application to be processed are recycled.

Operation 308, the resource to be processed is subjected to resource limitation processing according to the resource restriction policy.

A resource is a software or hardware resource that an electronic device must use to process an application event, such as an CPU, memory, hardware, network resources, and IO (Input-Output) of an electronic device. Resource limit processing refers to the process of restricting the resources occupied by the application. The resource limit processing can be, but is not limited to, controlling the application to enter a frozen state or a resource restricted state, and the application in the frozen state is not closed, but is not temporarily running. When the application is frozen, the application does not consume processor resources, but still occupies resources such as memory and hardware of the electronic device. The resource limit state refers to the state in which the resources of the electronic device used by the application at runtime are restricted. For example, the CPU usage of the control application at runtime cannot exceed 5%. The resource limiting process is performed on the to-be-processed application according to the resource restriction policy, which can limit the consumption of the electronic device resources by the background pending application.

In the above embodiment, the application processing method acquires the number of lost frames of the image frame when it is detected that the continuous image frame outputted by the electronic device is lost. The rating of the foreground application is determined according to the number of lost frames, and the pending application is obtained according to the foreground application. Then, the resource restriction policy is obtained according to the Carton level, and the resource restriction processing is performed on the application to be processed according to the obtained resource restriction policy. In this way, when the electronic device detects the stuck, the resources occupied by the background application are recovered by the resource limitation processing, so as to ensure the efficient operation of the foreground application and improve the operating efficiency of the application.

4 is a flow chart of an application processing method in another embodiment. The application processing method in this embodiment is described by using the terminal or server running in FIG. 1 as an example. As shown in FIG. 4, the application processing method includes operations 402 through 416. among them:

Operation 402, when the electronic device outputs a continuous image frame, acquires the number of lost frames of the image frame.

In one embodiment, the number of consecutive lost frames of the image frame may be acquired, and then the stuck level of the foreground application is obtained based on the number of consecutive lost frames. The number of consecutive lost frames refers to the number of consecutive lost image frames when the foreground application outputs the display during actual operation. The continuous image frames output by the foreground application in the electronic device are arranged according to a certain regularity. The so-called continuous loss is the uninterrupted loss, that is, the number of consecutive loss of image frames. The continuous image frames played in the electronic device are marked by the image frame identifier and arranged in a certain order. The electronic device obtains the image frame identifier corresponding to the actually output image frame, and can know which image frames are lost when outputting. . For example, the continuous image frame played by the electronic device includes 10 image frames, and the image frame identifiers corresponding to the first image frame to the last image frame are “01”, “02”, . . . “10”, respectively. Assuming that the electronic device outputs a continuous image frame, the actual output image frame sequence is "01" → "02" → "03" → "07" → "08" → "09" → "10", then the electronic device output can be judged. In the case of consecutive image frames, the lost image frames are "04", "05", "06", and since "04", "05", and "06" are consecutive image frames, the number of consecutive lost frames of the acquired image frames It is 3 frames.

It can be understood that, since the electronic device intermittently loses the image frame during the process of outputting the continuous image frame, the electronic device can acquire the number of consecutive consecutive lost frames and obtain the maximum consecutive lost frames according to the maximum consecutive lost frames. Get the Carton level. For example, the electronic device outputs consecutive image frames whose image frame identifiers are “01”, “02”, . . . “10”, and the actual output image frame sequence is “01”→“02”→“03”→“07” → “10”, it can be judged that when the electronic device outputs continuous image frames, the lost image frames are “04”, “05”, “06”, “08”, “09”. Among them, “04”, “05” and “06” are consecutive image frames, “08” and “09” are consecutive image frames, and the consecutive lost frames corresponding to “04”, “05” and “06” are In 3 frames, the number of consecutive lost frames corresponding to "08" and "09" is 2 frames, so the maximum number of consecutive lost frames acquired is 3 frames. The electronic device can continuously update the maximum number of consecutive lost frames during playback.

In an embodiment, the continuous image frame outputted by the electronic device may be further divided into a preset number of image frame sequences, and then the lost frame of the image frame in each image frame sequence is counted when the electronic device outputs the continuous image frame. Number, and obtain the maximum number of lost frames from the number of lost frames obtained; obtain the Karten level of the foreground application according to the maximum number of lost frames. For example, it is necessary to output consecutive image frames whose image frame identifiers are “01”, “02”, . . . “18”, and divide the continuous image frame into “01”, “02”, . . . “06”, “ 07", "08"...."12" and "13", "14".."18" three image frame sequences, each electronic image frame sequence is counted when the electronic device outputs continuous image frames. The number of lost frames of the corresponding image frame, and the maximum number of lost frames is obtained from the number of lost frames obtained. It can be understood that when the electronic device outputs a continuous image frame, each complete output of one image frame sequence generates a corresponding number of lost frames. Therefore, during the process of outputting consecutive image frames, the maximum number of lost frames is continuously updated.

Operation 404, determining a target frame number interval in which the number of lost frames falls, and obtaining a carton level of the foreground application according to the target frame number interval.

The number of lost frames is divided into two or more frame number intervals in advance, and then the correspondence relationship between each frame number interval and the Karton level is established. When the number of lost frames is obtained, the target frame number range in which the number of lost frames falls is obtained, and then the corresponding card level is obtained according to the target frame number interval. It can be understood that the divided frame number interval can be set according to the total number of consecutive image frames. For example, the frame number interval may be set according to the percentage of the total number of consecutive image frames, for example, the number of lost frames is divided into 4 frame number intervals, which may be 0 to 25%, 25% to 50%, 50% according to the total number. 75% and 75% to 100% calculate the frame number interval.

Operation 406: Obtain a dependent application that is dependent on the foreground application from the background application, and obtain a background application other than the dependent application as the to-be-processed application.

In one embodiment, relying on data that indicates that one application needs to utilize one or more applications can successfully implement the relationship to the execution of that one application. There are two applications with dependencies, namely the dependent application and the dependent application. For example, the application A depends on the application B, or the application B is dependent on the application A, that is, the application A needs to utilize the data of the application B to implement the execution of the application A. At this time, the application A is an application that depends on application B, and application B is an application that is dependent on application A. Specifically, in the embodiment of the present application, the dependent application refers to a background application that is relied upon by the foreground application.

The dependencies between applications are not constant, but change in real time. Electronic devices can record dependencies between applications. Specifically, the interdependencies between two applications are based on the fact that they need to communicate with each other. Therefore, obtaining the dependent application corresponding to the foreground application comprises: obtaining a background application having a communication relationship with the foreground application as a dependent application.

In the operating system, the communication relationship between applications is established by defining a communication mechanism. Among them, the communication mechanism includes Socket, Binder, shared memory and so on. Binder communication is an efficient IPC (Inter-Process Communication) mechanism implemented in the Android system. It is a client-server (client-server) communication structure. The client and the server define a corresponding proxy interface. When the client invokes the method in the proxy interface, the proxy interface method packages the client parameters into a Parcel object, and then the proxy interface sends the Parcel object to the Binder in the kernel layer. drive. The server can read the request data in the Binder driver, then parse and process the Parcel object, and return the processing result. Socket communication allows communication between two network applications to enable data exchange between applications on the network. Specifically, local inter-application communication can uniquely identify an application through PID (Process Identity), but there is no way to communicate between network applications. In the network communication, the IP (Internet Protocol) protocol can uniquely identify the host in the network. The "protocol + port" can uniquely identify the application in the host, so in the Socket communication, it is usually passed. IP address + protocol + port" form to uniquely identify an application. Shared memory allows two unrelated applications to access the same logical memory. Shared memory is a very efficient way to share and transfer data between two running applications. Memory shared between different applications. Usually arranged as the same piece of physical memory.

Optionally, obtaining the dependent application corresponding to the foreground application includes at least one of the following methods: acquiring a background application having a socket communication relationship with the foreground application as a dependent application; acquiring a binder communication relationship with the foreground application. A background application, as a dependent application; a background application that shares memory with the foreground application as a dependent application.

Operation 408, when the Karton level is greater than the level threshold, acquiring the first resource restriction policy.

The resource restriction policy is obtained according to the Karton level of the foreground application, and the resource restriction processing is performed on the application to be processed according to the resource restriction policy. The resource restriction policy may be divided into a first resource restriction policy and a second resource restriction policy. The first resource restriction policy refers to a policy for controlling a pending application to enter a frozen state according to a Carton level, and the second resource restriction policy refers to a The level controls the policy that the pending application enters the resource limit state.

Operation 410: Acquire a second resource restriction policy when the Carton level is less than or equal to the level threshold.

In one embodiment, when the Karton level is greater than the level threshold, indicating that the running application of the foreground application is relatively serious, the acquired pending application may be frozen. The pending application after freezing cannot continue to run and does not consume CPU resources. When the Karton level is less than or equal to the level threshold, it indicates that the running of the foreground application is lighter, and the running state of the to-be-processed application can be maintained, and the pending application is restricted during the running process of the to-be-processed application. Occupied resources.

In operation 412, the to-be-processed application is subjected to resource limitation processing according to the first resource restriction policy; or the to-be-processed application is subjected to resource limitation processing according to the second resource restriction policy.

In the embodiment provided by the present application, the resource limiting processing of the to-be-processed application according to the first resource restriction policy includes: controlling the to-be-processed application to enter a frozen state. The pending application that enters the frozen state can no longer continue to run, which can reduce the resource consumption of the electronic device by the pending application. The frozen pending application can also be woken up, and the user or system can set the conditions for the wakeup.

In the Android system, there are various ways to implement application freezing and wake-up. For example, one can be implemented by the pm (package manager) command. In the pm command, the application can be set to a frozen state by the freeze command pm disable[–user USER_ID]PACKAGE_OR_COMPONENT, and then passed. The defrosting command pm enable[–user USER_ID]PACKAGE_OR_COMPONENT wakes up the application in the frozen state, and obtains the list of applications in the frozen state by freezing the list query command pm list packages–d to view the frozen application. It can be understood that the application processing method is described by taking the Android operating system as an example in the present application, but the application processing method of the present application is not limited to being implemented in the Android system, and can also be applied to the IOS (IPhone Operating System), In operating systems such as Symbian, Windows, and MAC OS (Macintosh Operating System).

In an embodiment, the resource limiting process to be processed by the application according to the second resource restriction policy includes: obtaining a corresponding resource restriction level according to the Carton level, and controlling the to-be-processed application to enter a resource restriction level corresponding resource limitation state, where The resource-restricted state application has a resource occupancy rate for the electronic device at runtime that is less than the occupancy threshold. When the to-be-processed application is in the resource-restricted state, the resource usage rate of the electronic device to be processed cannot exceed the occupancy threshold. This can control the resource usage of the electronic device by the application to be processed, and reduce the occupation of resources by the background. Improve the efficiency of the front desk. For example, controlling the CPU usage of the pending application at runtime should not exceed 5% to reduce the excessive consumption of the CPU by the application to be processed and reduce the user's dependence on the mobile phone. In the mobile phone system, cgroups (control groups) can be used to control the CPU usage, such as CPU, memory, and IO of the application to be processed, that is, the acquired application to be processed enters the resource limitation state.

The resource restriction level is used to indicate the degree of resource limitation to the application, and the correspondence between the carton level and the resource restriction level is established in advance. When the Karton level is less than or equal to the level threshold, the corresponding resource restriction level is obtained according to the Karton level. For example, the Carton level can be divided into four levels: Level 1, Level 2, Level 3, Level 4, etc., and the degree of Carton increases from Level 1 to Level 4. The level threshold may be level 3. When the level of the card is less than or equal to level 3, the corresponding resource restriction level is obtained according to the level of the card. The resource limit level can be divided into three levels: the light resource limit level, the common resource limit level, and the deep resource limit level. The corresponding card level is level 1, level 2, level 3, and the corresponding resource limit level is occupied. The rate threshold is different. It can be understood that the occupancy thresholds corresponding to different resources can also be set to be different. For example, the CPU usage threshold can be 5%, and the memory usage threshold can be 10%.

Operation 414, when it is detected that the foreground application switches to the background, starts timing.

After the resource restriction processing is performed on the application to be processed, the electronic device can monitor the foreground application. When the current application switches to the background, the electronic device starts the timer and then starts counting through the timer. The timer established by the electronic device can be associated with the foreground application, and when the current application switches to the background, the start timer starts counting. Specifically, the correspondence between the foreground application identifier of the foreground application and the timing identifier of the timer is established in advance, and the timer is searched for and started by the timer identifier corresponding to the foreground application identifier. Taking the Android system as an example, the system can predefine a timer. When it detects that the foreground application switches to the background, the foreground application identifier searches for the corresponding timer, and clears the timer by timer.setBase(SystemClock.elapsedRealtime()). Zero, then start the timer through the timer.start() function and start timing.

At operation 416, when the timing duration exceeds the duration threshold, the pending application is controlled to return to the normal operating state.

When the timing duration exceeds the duration threshold, the pending application is restored to normal operation. Specifically, when the to-be-processed application is in the resource-restricted state, the resource limitation of the electronic device to be processed by the application is released. The pending application wakes up from a frozen state when the pending application is frozen. After returning to normal operation, the pending application's use of electronic device resources is no longer restricted. In addition, when a switching instruction to switch the application to be processed from the background to the foreground is detected, the pending application is controlled to return to the normal operating state. This ensures that the pending application can process the instructions of the electronic device in time and improve the operating efficiency of the electronic device.

FIG. 5 is a schematic diagram of a resource restriction state of an application in an embodiment. As shown in FIG. 5, the resources of the electronic device include a CPU, a memory, an IO, a network resource, and the like, and the state of the application may be classified into a normal running state, a resource limiting state, and a frozen state. The resource restriction state may be further divided into a light resource restriction state, a normal resource restriction state, and a deep resource restriction state. In different resource limitation states, the corresponding available resource 502 and the unavailable resource 504 are different. From the light resource limit state, the normal resource limit state to the deep resource limit state, the available resource 502 is decremented. In normal operation, the application's available resource 502 is 100%.

In the above embodiment, the application processing method acquires the number of lost frames of the image frame when it is detected that the continuous image frame outputted by the electronic device is lost. The rating of the foreground application is determined according to the number of lost frames, and the pending application is obtained according to the foreground application. Then, the resource restriction policy is obtained according to the Carton level, and the resource restriction processing is performed on the application to be processed according to the obtained resource restriction policy. In this way, when the electronic device detects the stuck, the resources occupied by the background application are recovered by the resource limitation processing, so as to ensure the efficient operation of the foreground application and improve the operating efficiency of the application.
