In the embodiment of the present application, the processor 110 may execute the instructions stored in the internal memory 121 to perform fine-grained control over resource usage according to the process type in the foreground application. Compared with the prior art that allows each process in the foreground application to use various resources normally, the resource management and control method provided by the embodiment of the present application can reduce unnecessary system overhead and ensure the use of resources in the foreground process under the condition of ensuring services. experience.

The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiments of the present application take an Android system with a layered architecture as an example to exemplarily describe the software structure of the electronic device 100 .

FIG. 2 is a block diagram of a software structure of an electronic device 100 according to an embodiment of the present invention.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into five layers, from top to bottom, the application layer, the application framework layer, the Android runtime (ART) and native C/C++ libraries, the hardware abstraction layer and the kernel Floor.

The application layer can include a series of application packages.

As shown in Figure 2, the application package can include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, weather, browser, etc.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include window managers, content providers, view systems, resource managers, notification managers, activity managers, input managers, and so on.

The window manager provides window management services (window manager service, WMS), WMS can be used for window management, window animation management, surface management and as a transfer station for the input system.

Content providers are used to store and retrieve data and make these data accessible to applications. This data can include video, images, audio, calls made and received, browsing history and bookmarks, phone book, etc. Content providers provide support for data access between applications.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. View systems can be used to build applications. A display interface can consist of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The resource manager provides various resources for the application, such as localization strings, icons, pictures, layout files, video files and so on.

The notification manager enables applications to display notification information in the status bar, which can be used to convey notification-type messages, and can disappear automatically after a brief pause without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also display notifications in the status bar at the top of the system in the form of graphs or scroll bar text, such as notifications of applications running in the background, and notifications on the screen in the form of dialog windows. For example, text information is prompted in the status bar, a prompt sound is issued, the electronic device vibrates, and the indicator light flashes.

The activity manager can provide activity management services (activity manager service, AMS). The activity manager is used to manage activities, and is responsible for the startup, switching, scheduling of various components in the system, and the management and scheduling of applications.

The input manager can provide an input manager service (IMS), and the IMS can be used to manage the input of the system, such as touch screen input, key input, sensor input, and the like. IMS fetches events from input device nodes, and distributes events to appropriate windows through interaction with WMS.

The Android runtime includes the core library and the Android runtime. The Android runtime is responsible for converting source code to bytecode, converting bytecode to machine code, and running the machine code. In terms of compilation technology, the Android runtime supports ahead or time (AOT) compilation technology and just in time (JIT) compilation technology, in which AOT converts bytecode into machine code during application installation and stores it in On-memory; the JIT converts a portion of the bytecode to machine code in real-time while the application is running.

The core library is mainly used to provide the functions of basic Java class libraries, such as basic data structures, mathematics, IO, tools, databases, networks and other libraries. The core library provides an API for users to develop Android applications.

A native C/C++ library can include multiple functional modules. For example: surface manager, media framework, libc, OpenGL ES, SQLite, Webkit, etc. Among them, the surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications. The media framework supports playback and recording of many common audio and video formats, as well as still image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. libc provides a library of standard C functions. OpenGL ES provides the drawing and manipulation of 2D graphics and 3D graphics in applications. SQLite provides a lightweight relational database for applications. Webkit provides browser kernel support.

The modules in the application framework layer are written in the Java language, and the modules in the native C/C++ library are written in the C/C++ language, and the communication between the two can be realized through the Java native interface (JNI).

The hardware abstraction layer runs in user space, encapsulates the kernel layer driver, and provides a calling interface to the upper layer, which can include a display module, a camera module, an audio module, and a Bluetooth module.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, sensor driver, Binder driver, etc. In addition to providing hardware drivers, the kernel layer also supports functions such as memory management, system process management, file system management, and power management.

The user performs an input operation on the electronic device 100 (such as an operation that triggers the electronic device to display an application), and the kernel layer can generate a corresponding input event (such as a folding screen unfolding event) according to the input operation, and report the event to the application framework layer. event. The window properties of the application are set by the activity management server AMS of the application framework layer. The window management server WMS of the application framework layer draws the window according to the settings of the AMS, and then sends the window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface on the folding screen.

The properties of the window may include the position and size of the Activity window, and the visible properties of the Activity window (ie, the state of the Activity window). The position of the Activity window is the position of the Activity window on the display screen, and the size of the Activity window may be information such as width and height in the application startup config. The visible property of the Activity window can be true or false. When the visible property of the Activity window is true, it means that the Activity window is in an active state, and the Activity window is visible to the user, that is, the display driver will display the content of the Activity window. When the visible attribute of the Activity of the Activity window is false, it means that the Activity window is in the pause state, and the Activity window is invisible to the user, that is, the display driver will not display the content of the Activity window.

Wherein, the application can call the start Activity interface to start the corresponding Activity. In response to the invocation of the application, the activity manager AMS may request the window manager WMS to draw a window corresponding to the Activity, and invoke the display driver to display the interface.

In the embodiments of the present application, the resource manager in the application framework layer can perform fine-grained control over resource usage for the processes in the foreground application. Therefore, compared with allowing each process in the foreground application to normally use each resource, the resource management and control method provided by the embodiment of the present application can reduce unnecessary system overhead and reduce the power consumption of the electronic device.

The resource management and control method provided by the embodiment of the present application will be described below by taking the electronic device 100 having the structure shown in FIG. 1 and FIG. 2 as an example. Referring to Figure 3, the method may include:

S301: Detect a first application program in a foreground running state.

Exemplarily, the running state of the application in the operating system can be divided into a foreground running state and a background running state. Among them, an application running in the foreground is also called a foreground application, and an application running in the background is also called a background application. The foreground running state can be that the application program runs directly on the display window or interface of the display screen, showing the current interface of the program running, or the user of the electronic device (that is, the user) interacts with the application through the interface displayed by the application program. . The foreground running state can also be that an application applies for a new Activity (startActivity) through the activity manager AMS, or the Activity in the Paused state re-enters the active state. In the background running state, the display screen does not present the running interface of the application, but the application continues to provide services in the background. For an application with a visual display interface, it can switch from the background running state to the foreground running state at any time, or from the foreground running state to the background running state; for applications without a visual display interface, its Can be in the background running state, but cannot switch to the foreground running state.

Exemplarily, after the electronic device 100 detects the first operation instructing the user to open the first application, the electronic device 100 runs the first application in the foreground.

The first application program may be a system application program or a third-party application program, which is not limited in this embodiment of the present application. The user may instruct the electronic device 100 to open the first application by clicking on the icon of the first application, a voice command, or a gesture in various manners.

Exemplarily, as shown in (a) of FIG. 4 , taking the first application as a browser as an example, the electronic device 100 detects the first operation of the user clicking the browser icon 401, and in response to the first operation, the electronic device 100 100 Starts the browser application in the foreground. As shown in (b) of FIG. 4 , after the electronic device 100 starts the browser application, the interface of the browser is displayed on the screen, and the application browser is in the foreground running state at this time.

Exemplarily, one or more applications may run simultaneously on the electronic device 100, including applications running in the foreground and applications running in the background, and there may be various implementations for determining whether a system application is running in the foreground. In a possible implementation manner, after the first application program is opened, the Android operating system will call methods such as onResume to make the Activity of the first application program in a running state. Among them, Acticity is a component used to control the display interface, which can provide users with an interface for interacting with the system, and each application has one or more Acticities. If the first application program has a visible display interface, after the Activity of the first application program is started, the Activity includes: running the Resumed state, pausing the Paused state and stopping the Stopped state; and then, if the Activity of the first application program is in the Resumed state, It means that the first application is in the foreground running state, and if the Activity of the first application is in the Paused state, it means that the first application is running in the background. If the first application program does not have a visible display interface, after the Activity of the first application program is started, the Activity includes: a Resumed state and a Stopped state; further, if the Activity of the first application program is in the Resumed state, it means that the first The application is running in the background. In this way, it can be determined whether the application is in the foreground running state according to the state of the Activity of the system application.

In some embodiments, when the touch focus of the application UI layer displayed on the display screen of the electronic device 100 changes, the application of the currently focused layer can be acquired with a delay of 100ms as the currently visible first application. If the first application If the interface component of the program is in the running state, it means that the first application is in the foreground running state, and the first application is set to the foreground flag; otherwise, the first application is set to the background flag.

In other embodiments, when the electronic device 100 is unlocked, the currently visible first application can be obtained immediately. If the interface component of the first application is in the running state, it means that the first application is in the foreground running state, and the first application is in the foreground running state. The application sets the foreground flag, otherwise, the first application sets the background flag.

Exemplarily, in the Android operating system, if the currently visible Activity of the first application is in the Resumed state, it means that the first application is in the foreground running state.

S302: For the first application program determined in step S301, identify the non-critical process of the first application program.

In some embodiments, the electronic device 100 may identify the non-critical process in the first application program according to the type of business performed by the process.

For one or more applications in the electronic device 100, the electronic device 100 usually creates multiple business processes for it, so as to execute different services to realize corresponding functions. For example, when the foreground application is a browser, the electronic device 100 may create one or more of the browser main process, the web browsing process, and the download service process; for another example, when the foreground application is a navigation application, The electronic device 100 may create one or more of a navigation application main process, a map navigation process, and a message push process.

Wherein, each business process in the foreground application can apply for resources, and the resources may include software resources and/or hardware resources, so as to support the normal operation of various functional services of the foreground application.

Exemplarily, for an application running in the foreground, its business types can be divided into foreground business and non-foreground business, where the foreground business can be the business that the user directly interacts with, and the non-foreground business can be the one that the user does not directly interact with. Interactive business. Exemplarily, taking the browser as the first application running in the foreground as an example, see (b) in FIG. 4 , when the user uses the browser to browse the webpage, the webpage browsing process belongs to the foreground business process.

In some embodiments, for the first application determined in step S301, in the life cycle of the first application in the foreground running state, when a certain process of the first application does not run the UI component and will not be called by the foreground UI thread , the process is a non-foreground business process of the first application. Specifically, in the Android operating system, if a certain process does not run the UI component, it may be that the process does not run the Activity. Among them, each application running in the foreground corresponds to a user interface (UI), and the UI thread is created when the application is started, and is mainly used to control the display, update and control interaction of the UI interface.

In other embodiments, the electronic device 100 may learn and identify whether the process is a non-critical process according to the characteristics of the process. Alternatively, the cloud server may learn and identify whether the process is a non-critical process according to the characteristics of the process, and the electronic device 100 may obtain the identification result of the process from the cloud server.

For an application running in the foreground state, the electronic device 100 can obtain the types of various business processes. Optionally, the business process may include a perceptible process and an imperceptible process, and the like. A perceptible process can be a running business process that the user can hear, see, or touch, such as a message receiving/sending process, an alarm clock process, an upload/download process, an audio playback process, or a navigation process. Not limited to this. Although the perceptible process has entered the background, it can still be perceived by the user that the business is running. The imperceptible process may be a running business process that cannot be perceived by the user.

In some embodiments, the electronic device 100 may learn and identify whether a process is a perceptible process or an imperceptible process according to the characteristics of the process. Alternatively, the cloud server may learn and identify whether the process is a perceptible process or an imperceptible process according to the characteristics of the process, and the electronic device 100 may obtain the identification result of the process from the cloud server.

If the processes satisfy the target characteristics generally associated with the user's perception shown in Table 1, the electronic device 100 may determine that these processes are user-perceivable processes.

For example, referring to FIG. 5 , the electronic device 100 may collect heartbeats, network data packets by process, record notifications, vibrations, or collect other related information of the process. The electronic device 100 identifies whether the process characteristics shown in Table 1 are met according to the relevant information; if so, the electronic device 100 determines that the process is a perceptible process; if not, the electronic device 100 determines that the process is an imperceptible process. Among them, having network authority means that the process has the authority to use network resources and can use network resources normally.

Alternatively, the electronic device 100 can collect heartbeats, network data packets, record notifications, vibrations, or other related information of the process according to the process, and upload it to the cloud server. The cloud server identifies whether the process characteristics shown in Table 1 are met according to the relevant information of the process; if so, the cloud server determines that the process is a perceptible process; if not, the cloud server determines that the process is an imperceptible process. The cloud server returns the identification result of the process to the electronic device 100 .

It should be noted that whether the electronic device 100 or the cloud service determines whether the process is a perceptible process or an imperceptible process according to the process characteristics can be performed after the first application enters the foreground running state; Save the training result of process identification and save it in the list of perceptible and non-perceptible processes. Perceived and imperceptible processes can also be preset.

Table 1

In some embodiments, the non-critical process of the first application may be a non-foreground business process of the first application, or may be an imperceptible process of the first application.

In other embodiments, the non-critical process of the first application may be an imperceptible process in the non-foreground business process of the first application. For the user-insensitive process, the user cannot directly perceive the service. Therefore, in practical applications, for the non-foreground service process of the first application, the electronic device 100 retains the perceptible process in it, and performs resource management and control on the non-perceived process in it, which can not affect the foreground service and user experience on the basis of , reduce the power consumption of electronic equipment.

After determining the non-critical process of the first application, the electronic device 100 performs step S303 on the non-critical process determined in step S302.

S303: Determine the one-way process among the non-critical processes determined in step S302.

Among them, a one-way process can be a process that is not called by any other process.

In some embodiments, starting from the switching of the first application to the foreground running state, statistics on all processes on the electronic device 100 being invoked and/or invocation relationships are performed, and the invocation of the non-critical process determined in step S302 is obtained after a period of time after the statistics are started. As a result, a one-way process within it is identified.

In other embodiments, the non-critical processes determined in step S302 may be created from the time of creation, and the calling and/or calling relationships of all processes on the electronic device 100 may be counted, and the imperceptible processes determined in step S303 may be obtained after starting statistics for a period of time The result of the call to identify the one-way process.

Exemplarily, taking the Android operating system as an example, the calling relationship between all processes running on the electronic device 100 can be identified in the kernel Binder driver. In other embodiments, other methods may also be used to identify the logical relationship of calls between processes, which is not limited in this application.

FIG. 6 is a schematic diagram of the principle of inter-process communication of the Android operating system. Each Android operating system process can only run in the virtual address space owned by its own process. The virtual address space includes user space and kernel space independent of each other. For user space, different processes cannot share with each other, but the kernel space between different processes can be shared. Each communication between the two different processes is implemented through the Binder driver located in the kernel space.

The Binder mechanism adopts the client-server (Client-Server) communication mode, the application process acts as the client, the designated program acts as the server, and the two communicate through the Binder driver. In the related art, the client needs to transfer a piece of memory data to the server. The general method is that the client copies this piece of data from the client's process space to the kernel space, and then the kernel copies this piece of data from the kernel space to the kernel space. The process space on the server side, so the server side can access this piece of data, but this method performs two memory copy operations. The Binder mechanism only needs to copy the data of the client process space to the kernel space once, and then the server side shares this data with the kernel. The whole process only needs to perform a memory copy operation, which improves the operation efficiency.

Based on the principle of the above-mentioned Binder mechanism, the client process and the server process can be any two processes, either an application or a service. For example, it can be a communication between an application and an application, or between an application and a service. Communication.

In the embodiments provided in this application, the processes running in the system can communicate through the Binder mechanism. Inter-process calls are done through Binder shared memory.

In some embodiments, the calling relationship between all processes can be identified in the kernel Binder driver, and the logical relationship between the calls can be recorded. / or the specific case of the call.

FIG. 7 shows a schematic diagram of an inter-process calling relationship of an application. As shown in FIG. 7 , the main process A of the first application program derives three service sub-processes A1 , A2 and A3 . For the child process A1, it is called by the main process A and the child process A3, and calls the main process A at the same time, so the child process A1 has a two-way calling dependency. For the child process A2, it calls the main process A and the child process A3, but is not called by any other process, so the child process A2 is a one-way process. For the child process A3, it is called by the child process A2, and calls the main process A and the child process A1 at the same time, so the child process A3 has a two-way calling dependency.

FIG. 8 shows a schematic diagram of the mutual calling relationship between the processes of two application programs. As shown in FIG. 8 , the main process A of the first application program derives three service sub-processes A1 , A2 and A3 , and the main process B of the second application program derives three service sub-processes B1 , B2 and B3 . For the child process A1, it is called by the main process A, the child process A3, and the child process B3, and calls the main process A at the same time, so the child process A1 has a two-way calling dependency. For the child process A2, it calls the main process A and the child process A3, but is not called by any process, so the child process A2 is a one-way process. For the child process A3, it is called by the child process A2 and the child process B2, and calls the main process A and the child process A1 at the same time, so the child process A3 has a two-way calling dependency. For the child process B1, it is called by the main process B, the child process B2, and the child process B3, and calls the main process B at the same time, so the child process B1 has a two-way calling dependency. For the child process B2, it calls the child process B1, the child process B3 and the child process A3, but is not called by any other process, so the child process B2 is a one-way process. For the child process B3, it is called by the child process B2, and calls the child process A1 and the child process B1 at the same time, so the child process B3 has a two-way calling dependency.

S304: For the application in the foreground running state, perform resource management and control on the one-way process determined in S304.

Exemplarily, as shown in FIG. 7 and FIG. 8 , when the sub-process A2 and the sub-process B2 are non-critical processes, the electronic device 100 can perform resource management and control on the one-way process A2 and the one-way process B2.

Exemplarily, the manner in which the electronic device 100 performs resource management and control on the process may specifically include: suspending the Alarm heartbeat by process; disconnecting the TCP connection by process; restricting network permissions by process; caching or discarding broadcasts by process; pausing GNSS by process Use of resources such as /Wakelock/Job/broadcast, etc.

Among them, suspending the Alarm heartbeat by process refers to stopping the current process based on the Alarm's heartbeat packet. The TCP connection exchanges information through the Socket link. The TCP connection is disconnected by process, that is, the Socket link corresponding to the TCP connection of the current process is disconnected. Restricting network permissions by process means restricting the current process from using network resources. Pausing resources such as GNSS/Wakelock/Job/broadcast by process means that the current process is prohibited from using resources such as GNSS/Wakelock/Job/broadcast. Wherein, suspending the broadcast resources by process includes caching or discarding the broadcast content of the current non-critical process.

In another possible implementation, performing resource management on a process can restrict the process from using one or more resources. For example, the electronic device 100 may restrict the process to use the socket link and network resources, but allow the process to use the Alarm resource normally.

In another possible implementation manner, the manner in which the electronic device 100 performs resource management and control on the process may also be other manners, which are not limited in this application.

For the application in the foreground running state, performing resource management and control on the one-way process determined in step S304 can reduce the system overhead and ensure the resource usage experience of the foreground business process under the condition that the foreground business process is not affected.

In another possible implementation manner, in step S304, for the application in the foreground running state, among the non-critical processes determined in step S302, the process that has been called a few times, or the process that has not been called for a long time, or satisfies The process of the preset calling scene is used for resource management and control, which can further reduce the system overhead, and at the same time ensure that the foreground business process is not affected as much as possible.

After step S304, the method may further include:

S305: Stop performing resource management and control on the one-way process determined in step S304.

In some embodiments, for a non-instant messaging application, when it is detected that the one-way process determined in step S304 receives a broadcast or broadcast ANR, and a service ANR, input ANR, or Binder call occurs, the resource management and control of the process is stopped immediately.

In some embodiments, for an instant messaging application, when it is detected that the one-way process determined in step S304 receives a data packet from the network side, the resource management and control of the process is stopped.

In another possible implementation manner, the manner in which the electronic device 100 stops performing resource management and control on the one-way process may also be other manners, which are not limited in this application.
