Description

Application program background process management method and device

technical field

The invention belongs to the technical field of mobile terminals, and in particular relates to a method and device for managing background processes of application programs.

Background technique

Existing mobile terminals can support multi-task parallel processing. Users can open multiple applications at the same time. The process of the application that needs to be used currently runs in the foreground of the system, and the application that does not need to be used temporarily runs in the background of the system. If the user needs to switch applications When running a program, just transfer the application running in the background to the foreground. Since the opened application is always running in the background, you can quickly switch the background process to the foreground. However, this method of application process management is also There is a serious problem: because the process of the application program that is not used temporarily is always in the background of the system and can be called by the CPU, it will inevitably occupy a certain amount of system resources, and too many background processes will consume extra power. If the application program running in the background of the system is located Threads require a network connection, which consumes additional traffic.

Contents of the invention

In view of the above problems, the purpose of the present invention is to provide a method and device for managing background processes of application programs, aiming at solving the technical problems that existing background process management methods of application programs need to occupy additional resources and consume additional power and even traffic .

In one aspect, the application program background process management method includes:

After receiving the application program return instruction, transfer the process of the application program running in the foreground of the system to the background of the system;

Suspend the process running in the background of the system;

When receiving the process recovery instruction, resume the process of the application program corresponding to the process recovery instruction, and turn to the foreground to run.

On the other hand, the application background process management device includes:

The background transfer unit is used to transfer the process of the application program running in the system foreground to the system background after receiving the application program return instruction;

A process suspending unit, configured to suspend the process running in the background of the system;

The process recovery running unit is used for recovering the process of the application program corresponding to the process recovery command when receiving the process recovery command, and switching to the foreground to run.

The beneficial effects of the present invention are: in the technical scheme of the present invention, when the process of the application program is in the background of the system, the process can be suspended and will not be scheduled by the cpu, that is, it cannot continue to run, and part of the system resources are released; when the background application When the program needs to return to the foreground again, the previously suspended process is restored and transferred to the system foreground to run normally. Because in the present invention, the background process is suspended and cannot continue to run, system resources and power can be saved to a certain extent. In addition, the suspended process cannot connect to the network to avoid wasting additional traffic.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

Embodiment one:

Fig. 1 shows the flow of the application program background process management method provided by the first embodiment of the present invention, and only shows the part related to the embodiment of the present invention for the convenience of description.

The application background process management method provided in this embodiment includes the following steps:

Step S101, after receiving the application program return instruction, transfer the process of the application program running in the foreground of the system to the background of the system.

The application program described in this step is triggered by the user after returning the command. Specifically, an application program is running in the foreground of the system in the mobile terminal. The return key on the terminal interface triggers the generation of an application program return command. It should be noted that the return key is not an exit key, and does not exit the application program, but only transfers the application program to the system background.

Step S102, suspending the process running in the background of the system.

In this step, in order to make the process in the background of the system not called by the CPU, the process in the background of the system is suspended, and the operating authority of the process is limited.

Step S103 , when the process restoration instruction is received, restore the process of the application program corresponding to the process restoration instruction, and turn to the foreground to run.

The process recovery instruction described in this step is also triggered and generated by the user. Specifically, the user can directly open the suspended application program on the mobile terminal, including opening it in the program library or opening it in the history record. Limit the specific opening method of the application program. After clicking to open the application program that has been suspended, a process recovery instruction is generated. The instruction includes the relevant information of the application program that needs to be restored. According to the instruction, the process of the corresponding application program is resumed, and Turn to the foreground to run, and change the process permissions when implementing.

The application program background process management method provided by this embodiment suspends the background processes, limits the authority of these processes, and prevents them from being called and executed by the CPU, which can save CPU resources and also save power, and can also avoid wasting extra traffic in some cases .

Embodiment two:

Fig. 2 shows the flow of the application program background process management method provided by the second embodiment of the present invention, and only shows the part related to the embodiment of the present invention for convenience of description.

The application background process management method provided in this embodiment includes the following steps:

Step S201, after receiving the application program return instruction, transfer the process of the application program running in the foreground of the system to the background of the system;

Step S202, judging whether the process transferred to the system to run in the background satisfies the suspension policy;

Step S203, if the suspension policy is satisfied, then suspend the process transferred to the system to run in the background.

The above steps S202 and S203 are a specific preferred implementation of step S102 in the first embodiment. In this embodiment, all processes running in the background are not suspended. First, a suspension strategy needs to be defined, such as setting only for a certain Suspend the process of some applications. For example, for social applications, such as QQ, etc., you can keep them running in the background to ensure that you can receive messages in real time. For browsers, etc., you can suspend them. On the relevant setting interface of the mobile terminal, select the application that can be suspended in the background. In the specific implementation, you can judge whether the process where the current application program is located satisfies the suspension policy through relevant statements.

For example, for the JAVA language:

For C++ language:

Define the management class to make corresponding judgments to know whether the current process satisfies the suspension policy, and if so, suspend the process and make it in a suspended state.

Step S204, when the process running in the background of the system does not satisfy the suspension policy or the recovery policy, resume the process.

If the user changes the policy setting during use, so that when the process in the suspended state does not meet the suspension policy, the process will be restored, or the user can also set a recovery policy, and the process will be resumed when the recovery policy is met, for example, you can Set to suspend the background process for a period of time, resume the process, and suspend it again after a period of time. This embodiment does not limit the specific suspension strategy and recovery strategy, which can be modified and set according to actual conditions.

Specifically, corresponding to the JAVA language:

For C++ language:

The application program corresponding to the process can be resumed by judging whether the process is suspended and whether the suspension policy is satisfied.

Step S205 , when the process restoration instruction is received, restore the process of the application program corresponding to the process restoration instruction, and switch to the foreground to run.

The process recovery instruction described here is triggered by the user, and when the user starts the suspended application program, the process where the application program is located is resumed, and the application program is transferred to the foreground to run.

Step S206: Suspend the process running in the background that satisfies the suspension policy when receiving the process background management start instruction;

Step S207, when receiving the process background management closing instruction, resume all the processes suspended in the system background.

In the above two steps, it is considered that the user may modify the process management settings when using the mobile terminal, and the background management of the process can be set to be turned on or off on the relevant interface. This embodiment does not limit the specific sequence of steps, and the user can make relevant settings at any time . If the user sets to enable process background management, at this time, all processes currently running in the background are judged one by one, and when the suspension policy is satisfied, the process is suspended; similarly, the user can also choose to set to close the process background management, which corresponds to the current All suspended processes are resumed. In this embodiment, the user can choose whether to enable background process management, and there is no need to use this method for background process management, which increases the flexibility of the mobile terminal operation.
