The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In one embodiment, as shown in fig. 1, a schematic diagram of the internal structure of a terminal is provided. The terminal includes a processor, a memory, and a display screen connected by a system bus. Wherein, the processor is used for providing calculation and control capability and supporting the operation of the whole terminal. The memory is used for storing data, programs, and/or instruction codes, and the like, and the memory stores at least one computer program which can be executed by the processor to realize the application freezing method suitable for the terminal provided in the embodiment of the present application. The Memory may include a non-volatile storage medium such as a magnetic disk, an optical disk, a Read-Only Memory (ROM), or a Random-Access-Memory (RAM). For example, in one embodiment, the memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a database, and a computer program. The database stores data related to an application freezing method for implementing the embodiments, for example, information such as a name and an occupied memory size of each application or process may be stored. The computer program can be executed by a processor for implementing an application freezing method provided by various embodiments of the present application. The internal memory provides a cached operating environment for the operating system, databases, and computer programs in the non-volatile storage medium. The display screen may be a touch screen, such as a capacitive screen or an electronic screen, and is configured to display interface information of an application corresponding to the first process, and may also be configured to detect a touch operation applied to the display screen and generate a corresponding instruction, such as a switching instruction for performing foreground and background applications.

Those skilled in the art will appreciate that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration relevant to the present application, and does not constitute a limitation on the terminal to which the present application is applied, and that a particular terminal may include more or less components than those shown in the drawings, or may combine certain components, or have a different arrangement of components. For example, the terminal further includes a network interface connected via the system bus, where the network interface may be an ethernet card or a wireless network card, and the like, and is used for communicating with an external terminal, such as communicating with a server.

In one embodiment, as shown in FIG. 2, a partial architecture diagram of a terminal is provided. The architecture system of the terminal includes a JAVA space layer 210, a local framework layer 220, and a Kernel space layer 230. The JAVA space layer 210 may include a freezing and unfreezing application 212, and the terminal may implement a freezing policy for each application through the freezing and unfreezing application 212, and perform a freezing operation on the related application consuming power in the background. A resource priority and restriction management module 222 and a platform freeze management module 224 are contained in the local framework layer 220. The terminal can maintain different applications in organizations with different priorities and different resources in real time through the resource priority and restriction management module 222, and adjust the resource groups of the application programs according to the requirements of the upper layer, thereby achieving the effects of optimizing performance and saving power consumption. The terminal may allocate, by using the platform freezing management module 224, the task that can be frozen in the background to the freezing layers corresponding to the preset different levels according to the length of the freezing time, and optionally, the number of the freezing layers may include three, where: CPU limited sleep mode, CPU frozen sleep mode, process deep frozen mode. The CPU sleep-restricted mode is to restrict CPU resources occupied by related processes, so that the related processes occupy less CPU resources, and the vacant CPU resources are inclined to other processes which are not frozen, so that the occupation of the CPU resources is restricted, and the occupation of network resources and I/O interface resources by the processes is correspondingly restricted; the CPU freezing sleep mode means that related processes are forbidden to use the CPU, the occupation of a memory is reserved, and when CPU resources are forbidden to use, corresponding network resources and I/O interface resources are also forbidden to use; the process deep freezing mode is to further recycle the memory resources occupied by the relevant processes except for forbidding the use of CPU resources, and the recycled memory can be used by other processes. The kernel space layer 230 includes a UID management module 231, a Cgroup module 232, a Binder management module 233, a process memory recycling module 234, and a freeze timeout exit module 235. The UID management module 231 is configured to manage or freeze resources of the third-party application based on a User Identifier (UID) of the application. Compared with the Process control based on the Process Identifier (PID), the unified management of the resources of the application of one user is facilitated through the UID. The Cgroup module 232 is used to provide a complete set of resource restriction mechanisms related to Central Processing Unit (CPU), CPU set, memory, input/output (I/O) and Net. The Binder management and control module 233 is used for controlling the priority of background Binder communication. The interface module of the local framework layer 220 includes a binder interface that is issued to the upper layer, and the framework or application of the upper layer sends a resource restriction or freezing instruction to the resource priority and restriction management module 222 and the platform freezing management module 224 through the provided binder interface. The process memory recycling module 234 is used to implement a deep process freezing mode, so that when a third-party application is in a frozen state for a long time, a file area of a process is mainly released, thereby achieving a memory-saving module and increasing the speed of the application when the application is started next time. The freeze timeout exit module 235 is used to resolve the exception generated by the freeze timeout scenario. Through the above-mentioned architecture, the application freezing method in the embodiments of the present application can be implemented.

In one embodiment, as shown in fig. 3, an application freezing method is provided for freezing an application program running on a terminal. The embodiment is described by taking the method applied to the terminal shown in fig. 1 as an example. The application freezing method comprises the following steps:

step 302: and acquiring a background application program running on the terminal, and detecting whether the desktop plug-in exists in the background application program.

An Application (APP) refers to a computer program that performs one or more specific tasks, operates in a user mode, can interact with a user, and has a visual user interface. Background applications work in a background running state, and one application work in the background running state indicates that the application is located at a position corresponding to a non-top-of-stack window object of a window stack of an operating system. Determining whether a target application program is a background application program, acquiring a window object corresponding to the target application program, and judging whether the window object is positioned at the top of a window stack of an operating system, if not, indicating that the application program is the background application program, and if so, indicating that the application program runs on a foreground application program.

Desktop plug-ins are technologies that facilitate users to quickly use certain application functions without entering applications in a mobile operating system. The application program provides various services which enable the plug-in to be applied, and comprises a loading mode, so that the plug-in can be loaded into the application program and a network transmission protocol to exchange data with the plug-in. The plug-in must rely on the application to function itself, and the plug-in cannot function properly only. In using desktop plug-ins, the application is still caused to run in the background. When the application enters the background, if the application is directly frozen, the function of the desktop plug-in of the application can be influenced.

Step 304: and if the background application has the desktop plug-in, judging whether to freeze the background application program corresponding to the desktop plug-in according to the type of the desktop plug-in.

If the running background application program has the desktop plug-in corresponding to the running background application program, the data related to the background application program is shown on the terminal desktop. The desktop plug-ins are mainly divided into input type plug-ins and output type plug-ins. The input plug-ins include desktop plug-ins for displaying output results according to input data, that is, desktop plug-ins capable of displaying output results according to data input by a user only when data input by the user is detected, such as desktop plug-ins for applications such as "drip travel, jingdong, and microblog. Outbound plug-ins include desktop plug-ins that are updated in real time, i.e., such plug-ins typically require updating the display state of the plug-in the background, such as the desktop plug-in for applications such as "weather, clock, traffic management", and the like. For an input type plug-in, the corresponding background application program can be frozen; for output type plug-ins, which need to update the display state in real time, freezing such applications can affect the user experience, and thus the running state of the output type plug-ins needs to be maintained.

Step 306: and when the background application program needs to be frozen, freezing the background application program according to a preset freezing strategy.

When the desktop plug-in exists in the background application running on the terminal, the terminal can judge whether the background application needs to be frozen according to the type of the desktop plug-in, and for the input type plug-in, the background application corresponding to the desktop plug-in can be frozen; for the output type plug-in, the running state of the background application corresponding to the desktop plug-in needs to be maintained. The background application program to be frozen is frozen according to a preset freezing policy, for example, a corresponding freezing policy may be set according to the monitored operation information to implement the freezing operation on the foreground application. For example, different freezing levels can be set according to the acquired use frequency of the desktop plug-ins, and freezing of foreground applications can be realized according to the freezing levels.

According to the application freezing method, the background application program running on the terminal is obtained, whether the desktop plug-in exists in the background application program is detected, if the desktop plug-in exists in the background application program, whether the background application program corresponding to the desktop plug-in is frozen is judged according to the type of the desktop plug-in, when the background application program needs to be frozen, the background application program is frozen according to a preset freezing strategy, whether the corresponding background application program is frozen can be judged according to the working type of the desktop plug-in, the freezing error rate is reduced, and the frozen application is more reasonable.

In an embodiment, as shown in fig. 4, the determining whether to freeze the background application corresponding to the desktop plug-in according to the type of the desktop plug-in includes:

step 402: and acquiring the desktop plug-in corresponding to the background application program, and detecting the work type of the desktop plug-in.

When the desktop plug-in is detected to exist in a background application running on a terminal, the desktop plug-in corresponding to the background application is obtained, and the working type of the desktop plug-in is detected, wherein the desktop plug-in is mainly divided into an input type plug-in and an output type plug-in. The input plug-ins include desktop plug-ins for displaying output results according to input data, that is, desktop plug-ins capable of displaying output results according to data input by a user only when data input by the user is detected, such as desktop plug-ins for applications such as "drip travel, jingdong, and microblog. Outbound plug-ins include desktop plug-ins that are updated in real time, i.e., such plug-ins typically require updating the display state of the plug-in the background, such as the desktop plug-in for applications such as "weather, clock, traffic management", and the like.

For example, the terminal may detect a process of the desktop plug-in according to a preset frequency or according to a detected user operation instruction, and obtain a current working type of the desktop plug-in by detecting a process state of the desktop plug-in. The running of an application is usually reflected by the running of related processes, so that the running of desktop plug-ins is also related to the processes. Optionally, a process identifier of the desktop plug-in may be obtained, where the process identifier is used to uniquely identify a corresponding process, and may be formed by one or a combination of several of numbers, letters, or other characters with preset digits. For example, process a may be represented by process identifier "0001", process B may be represented by "1234", and the running state of the processes of different process identifiers may be detected, so that the work type of the desktop plug-in may be known.

Step 404: and when the desktop plug-in belongs to the input type plug-in, freezing the background application program corresponding to the input type plug-in.

Detecting the working type of the desktop plugin, when the desktop plugin belongs to an input type plugin, the plugin often needs to display an output result according to data input by a user, and if the data input by the user is not detected, the current use requirement of the user on the desktop plugin is low, and a background application program corresponding to the input type plugin can be frozen.

Step 406: and when the desktop plug-in belongs to the output type plug-in, keeping the running state of the background application program corresponding to the output type plug-in.

The method comprises the steps of detecting the working type of the desktop plugin, when the desktop plugin belongs to an output type plugin, generally updating the display state of the plugin in the background, and freezing the application program corresponding to the plugin can cause the desktop plugin to be incapable of normally running to influence user experience, so that the running state of the background application program corresponding to the output type plugin needs to be maintained.

In one embodiment, as shown in fig. 5, the freezing the background application according to the preset freezing policy includes:

step 502: acquiring the use frequency of the desktop plug-in corresponding to the background application program to be frozen;

because the desktop plug-in corresponding to the background application program needing to be frozen is an input type plug-in, the terminal can acquire the operation information input by the user when each desktop plug-in runs, and count the historical operation records of each desktop plug-in receiving the user input each time. The historical operation record comprises historical operation modes and use frequencies corresponding to the operation modes. The historical operation modes at least comprise operation modes such as key pressing, voice, touch, fingerprint, scanning and the like, and the use frequency corresponding to the operation modes is the use frequency of each operation mode.

For example, when the desktop plug-in runs an Application (APP) of a player such as "OPPO video player", the terminal records a starting time point when the desktop plug-in starts running the "OPPO video player", and an ending time point when the desktop plug-in ends or switches to the background, and a time duration between the starting time point and the ending time point is a historical running time duration, such as 120 minutes. In the historical operating time length, the input operation modes of the receiving user comprise operation modes such as touch input and sliding input. According to the input operation mode, the use frequency of each operation mode can be acquired, wherein the use frequency of the touch input operation mode is 2 times/60 minutes, and the use frequency of the slide input operation mode is 6 times/60 minutes.

Step 504: dividing freezing grades according to the mapping relation between the use frequency and the freezing degree; the freeze level is used to indicate a maximum allowed resource that can be used to configure the background application.

And dividing the freezing grade according to the acquired use frequency of the desktop plug-ins. Wherein the freeze level is used to indicate a maximum allowed resource that can be used by the configuration foreground application. The resource that can be used represents the resource that can be used by the process at each time when the process is executed. The maximum allowed resource represents the maximum resource that a process is allowed to use at each time. The lower the use frequency is, the higher the freezing level is, and the less the maximum allowed resources can be used by the corresponding background application program; conversely, the higher the frequency of use, the lower the freeze level, and the greater the maximum allowed resources that can be used by the corresponding background application.

In the operating system, the interaction mechanism between the processes is mainly divided into a synchronization mechanism and a communication mechanism. The communication mechanism includes socket, binder, shared memory, etc. Two programs on the network effect the exchange of data via a bidirectional communication link, one end of which is called a socket. Binder is an inter-process communication mechanism that provides remote procedure call functionality.

The terminal can acquire the background process according to a preset frequency or according to a detected user operation instruction. Optionally, a process identifier of the background process may be obtained, where the process identifier is used to uniquely identify a corresponding process, and may be formed by one or a combination of several of numbers, letters, or other characters with preset digits. For example, process A can be represented by process identification "0001", process B by "1234", and so on.

It should be noted that the freezing level dividing manner may be set according to the requirement of the user, and may be set in combination with the historical running time of the background application and the application type of the background application. The freezing levels of each application program may be the same or different in division rule, and the number of the divided levels may be the same or different.

Step 506: and freezing the background application program at a corresponding level according to the freezing level.

And determining a freezing grade corresponding to the use frequency of the current desktop plug-in according to the use frequency of the desktop plug-in. If the memory required by the background application program is 40Mb when the background application program is executed, and if the freezing level is the first level (the lowest level), resources are allocated to the background application program according to the first freezing level, and the maximum allowed resources which can be used by the background application program are 30 Mb; and if the freezing level is four levels (the highest level), distributing resources to the background application program according to the first freezing level, wherein the maximum allowed resource which can be used by the background application program is 0 Mb. Wherein the highest level of freezing is a completely frozen state.

The resources may include a CPU, I/O file resources, and the like. Taking resources as a memory for example, the longer the interval time is, the higher the freezing level is; the higher the freeze level, the less maximum allowed resources that the background application can use.

In the method, the freezing level is set according to the use frequency of the desktop plug-in, the lower the use frequency is, the higher the freezing level is, but the maximum allowed resource which can be used by the background application is reduced along with the freezing level until the background application is in a complete freezing state. A certain time process is needed from partial freezing to complete freezing, a buffering time period is given to a user, and in the time period, the user can quickly and effectively unfreeze the background application, so that the user experience is improved. Meanwhile, the root freezing level limits the maximum allowed resource which can be used by the background application, and the resource can be reasonably distributed, so that the power consumption is reduced.

In one embodiment, as shown in fig. 6, the freezing the background application according to the preset freezing policy includes:

step 602: acquiring all functions of the background application program and functions used by the desktop plug-in of the background application program.

The background application program has various functions, and when the freezing condition is met, the functions used by the desktop plug-ins corresponding to the current background application program are obtained. An input operation to an input-type desktop plug-in may correspond to one or more functions, for example, a voice operation may correspond to functions of voice communication, voice control, voice search, etc., and a scan operation may correspond to functions of scan recognition, scan payment, scan authentication, etc. By acquiring the monitored operation mode, the function corresponding to the monitored operation mode can be acquired correspondingly.

It should be noted that the functional functions used by the desktop plug-in may also include, but are not limited to: recording, taking pictures, connecting with a network, using Bluetooth, acquiring geographic positions, making calls and sending short messages.

Step 604: and acquiring unused functions according to the functions used by the desktop plug-ins of the background application program.

When a user uses a desktop plug-in corresponding to a current background application program, a function which is not frequently used by the user generally exists. The unused function refers to a function other than the monitored function corresponding to the operation of the desktop plug-in, among all functions of the desktop plug-in.

Step 606: and freezing the corresponding process of the unused function in the system.

Each application corresponds to a process group in a system frame, and when the application is operated, the system can allocate resources to the corresponding process group; each function module in the application also corresponds to the process in the process group, so that the corresponding process of each function of the application is identified, and the subsequent system resource allocation management of the corresponding process is facilitated. The identifier is used for uniquely identifying the corresponding process and can be formed by one or a combination of several of numbers, letters or other characters with preset digits. For example, process A can be represented by process identification "0001", process B by "1234", and so on.

By the method, the terminal can freeze the corresponding process of the unused function in the system, and the aims of saving resources and improving the operation efficiency are fulfilled. But other functions of the background application program can still be used, so that the application does not need to freeze the whole application, but freezes partial functions of the application, and ensures normal use of other partial functions, thereby achieving the effect of reducing power consumption.

In one embodiment, after freezing the background application according to a preset freezing policy, the method further includes: when the background application program with the desktop plug-in is frozen, if the current display interface is detected to be the desktop, the background application program with the desktop plug-in is unfrozen.

Specifically, when the current display interface of the terminal is detected to be the desktop, a unfreezing instruction of the background application program with the desktop plug-in is generated. The information of the terminal display interface is detected in real time, and after the terminal display interface is detected to be a desktop, the use requirement of the desktop plug-in is increased, so that unfreezing operation needs to be carried out on the frozen application program and process related to the desktop plug-in. Further, when the current display interface of the terminal is detected to be the desktop, the terminal automatically generates a corresponding unfreezing instruction for unfreezing the application program and the process related to the desktop plug-in. Optionally, when the corresponding application program and process need to be defrosted after the background application program and the background process are frozen, a defreezing instruction input by a user may also be obtained. Biometric information is included in the thawing instruction, wherein the biometric information may be fingerprint information, iris information, voiceprint information, facial information, and the like. It should be noted that different applications may set different biometric information, or may set the same biometric information, and the biometric information may be set by user-defined settings according to the needs of the user.

In one embodiment, as shown in fig. 7, after freezing the background application according to the preset freezing policy, the method further includes:

step 702: obtaining a unfreezing instruction for unfreezing the frozen background application program;

step 704: detecting whether the biological characteristic information in the unfreezing instruction is matched with a preset biological characteristic;

step 706: and when the biological characteristic information in the unfreezing instruction is matched with the preset biological characteristic, unfreezing the background application program.

That is, when the background application is frozen and needs to be defrosted, the defreezing instruction input by the user needs to be acquired. Biometric information is included in the thawing instruction, wherein the biometric information may be fingerprint information, iris information, voiceprint information, facial information, and the like.

It should be noted that different applications may set different biometric information, or may set the same biometric information, and the biometric information may be set by user-defined settings according to the needs of the user.

And when the biological characteristic information in the unfreezing instruction is matched with the preset biological characteristic information, unfreezing the foreground application. And during the unfreezing operation, a corresponding unfreezing strategy can be set according to the freezing strategy, so that the unfreezing operation on the background application program is realized.
