FIG. 1 illustrates a method for application retention provided by an aspect of the present application. The method is executed on a device 1 and includes the following steps:

S11 When the application is detected to be returned to the background, the application holding process is activated;

S12: When the application holding process detects that an application holding condition is reached, perform a corresponding application holding processing operation based on the application holding condition.

In this application, the device 1 includes a smart device capable of running various applications. For example, the device 1 includes, but is not limited to, any mobile electronic product that can interact with a user through a touch panel, such as a smart phone, a tablet computer, and the like. The mobile electronic product may use any operating system, such as an android operating system, an iOS operating system, and the like.

In this embodiment, in step S11, when it is detected that an application is returned to the background, an application holding process is activated. Here, the application holding process is used to avoid being recycled when the application is returned to the background, for example, even if the application Back to the background, the application retention process can also keep the application from implementing related functions without being recycled by the system.

In this application, the detection of the application returning to the background can be implemented directly through the device 1 or through an application holding process. For example, when the application is started at the beginning, the application holding process is also started at the same time. During use, it can be set to the idle state without any operation, and when the application is returned to the background, the application holding process will be activated to take corresponding operations to keep the application from being recycled.

Here, the method for detecting whether the application is backed up to the background may be triggered by the application. For example, when the application is backed up to the background, the system may send an exit signal to the corresponding system of the device 1 or to the application holding process; it may also be The system or the application keeping process actively monitors, for example, whether the application is still running based on a preset time interval, and so on.

Continuing in this embodiment, in step S12, when the application holding process detects that an application holding condition is reached, a corresponding application holding processing operation is performed based on the application holding condition.

Wherein, the application holding condition includes conditions set to prevent the application from being recycled after being returned to the background, and accordingly, the application holding processing operation includes an operation of preventing the application returned to the background from being recycled. The application holding process monitors whether the application holding condition is met based on a preset manner, for example, it can monitor whether the application holding condition is met in real time or based on a preset time interval.

Preferably, the application retention condition includes a system memory consumption threshold, and the step S12 includes: when the application retention process detects that the current system memory consumption reaches the system memory consumption threshold, notifying the system to perform memory reclamation.

In this embodiment, since the system operation is affected when the system memory consumption is large, some systems set a preset value for the system memory consumption, and the memory is recycled when the system memory consumption reaches the preset value , Which may cause the application that is returned to the background to be recycled. Therefore, the application retention process can actively monitor the current system memory consumption and actively remind the system to perform memory recovery. For example, by setting a system memory consumption threshold, the threshold It can be slightly smaller than the preset memory consumption set by the system. When it is detected that the current system memory consumption reaches the system memory consumption threshold, the system is notified to perform memory reclamation.

Specifically, the way in which the application keeps the process monitoring the system's memory consumption can be implemented by calling the system interface. In addition, the way to notify the system to perform memory reclamation can be to actively kill useless processes or increase its own memory consumption by calling system methods. , Forcing the system to generate garbage collection and autonomously recover memory.

Here, the methods for monitoring system memory consumption and notifying system memory reclamation are merely examples. Other existing or possible monitoring system memory consumption and notification system memory reclamation methods, if applicable to this application, shall also be included The scope of this application is hereby incorporated herein by reference.

More preferably, the method further includes: S13 (not shown) raises the running level of the application holding process to prevent the application holding process from being recycled by the system.

In this embodiment, in order to prevent the system from recovering the application during the process of memory reclamation, the application may maintain the running level of the process.

Specifically, different systems have different priorities for processes. Therefore, different methods can be used to improve the running level of processes according to different systems. For example, in the android system, the foreground service or UI (User Interface) Has a higher priority, so when it is detected that the application holding process detects that the process is lower than the system process list priority threshold, the priority of the application holding process can be increased by creating a foreground service or UI level.

Preferably, the application retention condition includes an application recovery time threshold, and the step S12 includes: when the application retention process detects that the application reaches the application recovery time threshold, an active event is triggered to cause all The system gives the application a new application active cycle.

The application recovery time threshold includes a time value set by the application maintaining process to prevent the application from being recycled after the application is returned to the background. Generally, the system sets a preset application recovery time value, that is, When the time interval for the application to return to the background reaches the preset value of the application recycling time, the system will recycle the application. For example, some systems set a time threshold for application recycling to 15 minutes, that is, when the application returns to the background reaches 15 At the minute, the system will recycle the application, so in order to prevent the application from being recycled by the system, the application maintaining process triggers an active event by setting an application recycling time threshold, so that the system gives the application a new application active cycle In addition, the application recovery time threshold set by the application holding process should be smaller than a preset application recovery time set by the system to avoid applications being recycled. The specific application recovery time threshold setting is not described in this application. limited.

Here, the method of triggering an active event can be implemented by creating a foreground service. Here, the method of triggering an active event is only an example. Other existing or possible methods of triggering an active event that apply to this application are also applicable to this application. It should be included in the protection scope of this application, and is incorporated herein by reference.

Preferably, the application maintaining condition includes a system process list priority threshold, and the step S12 includes: when the application maintaining process detects that the process is lower than the system process list priority threshold, increasing the The application maintains the run level of the process.

In this embodiment, the system monitors the running process. For example, the process is monitored by the priority of the process list. The process with a higher priority will not be recycled by the system, and the process with a lower priority will be monitored by the system. Recycling. Therefore, you can set a priority threshold for the process list. When the priority is higher than the threshold, the process will not be recycled, and the process below the threshold will be recycled. Therefore, when the application maintains process monitoring When the process is lower than the system process list priority threshold, the running level of the application holding process is increased.

Specifically, different systems have different priorities for processes. Therefore, different methods can be used to improve the running level of processes according to different systems. For example, in the android system, the foreground service or UI has a higher priority. Therefore, when it is detected that the application holding process detects that the process is lower than the system process list priority threshold, the priority of the application holding process may be increased by creating a foreground service or UI.

Preferably, the application maintaining condition includes a memory consumption threshold of the application, and the step S12 includes: when the application maintaining process detects that the memory consumption of the application reaches the memory consumption threshold, releasing the The memory space of the application.

In this embodiment, if the memory consumption of an application is too large, it will affect the operation of the system. Therefore, some systems recycle these applications whose memory consumption is greater than a certain value. Therefore, the application retention conditions include the memory of the application. Consumption threshold, that is, when the memory consumption of the application reaches the memory consumption threshold, the application will release a certain amount of memory space to prevent the application from being recycled. Here, the setting of the memory consumption threshold is smaller than the system recycling the application. The specific memory consumption value reached can be adjusted according to different system correspondences, and is not limited here.

Preferably, before the step S12, the method further includes: S14 (not shown) to raise the running level of the application holding process; and / or release the memory space of the application.

In this embodiment, in order to better prevent the application from being recycled, after the application holding process is activated, the running level of the application holding process may be directly increased or the memory space of the application may be released, or the application may be upgraded. The application releases the memory space of the application while maintaining the running level of the process.

Preferably, in the present application, the application retention condition is set based on a system recovery condition, that is, in order to prevent the application from being recovered by the system, corresponding settings may be made for all conditions where the system may recover the application. For example, the system is in application After 15 minutes of returning to the background, the application retention process will trigger an active event to give the application a new application active cycle and so on before it reaches 15 minutes.

In this application, the detection of the application returning to the background can be implemented directly by the first device of the device 1, or can also be implemented by an application holding process. For example, when the application starts, the application holding process also starts at the same time. The process can be set to an idle state during application use, and no operation is performed. When the application returns to the background, the application maintaining process will be activated to take corresponding operations to keep the application from being recycled.
