In order to illustrate the technical solutions of the related art or the implementations of the present disclosure more clearly, the drawings used in the description of the implementations or the related art will be briefly described, it will be apparent that the drawings described in the following are implementations of the present disclosure, and it will be apparent to those skilled in the art that other drawings can be obtained from the drawings without any creative work.
Technical solutions in the implementations of the present disclosure will be described below clearly and completely in conjunction with the accompanying drawings in the implementations of the present disclosure. Obviously, the described implementations are some implementations of the present disclosure, not all of the implementations. On the basis of the implementations in the present disclosure, all other implementations obtained by a person skilled in the art without creative work should fall within the scope of protection of the present disclosure.
In present operating systems, about actions of applications, such as foreground applications and background applications, those would not known by the kernel, thereby, running requirements of the foreground applications and background applications cannot be matched precisely when processing a task scheduling and system running core number/frequency, thus causing performance problems (such as programs response slowly, stuck, etc) and power consume problems (such as the power consumes of background applications are too much, insignificant background applications are running continuously) are occurred.
To implement a method and an apparatus for application action synchronization, a terminal device, and a storage medium, a request for synchronizing actions of the foreground applications and/or background applications to the kernel space of the operating system is received, action categories of the foreground applications and background applications are obtained and an action determination is carried out, according to action parameters of the foreground applications and/or background applications, and results of the action categories and the action determination of the foreground applications and/or background applications are sent to the kernel space, the actions of the foreground, background applications to be synchronized to the kernel space would be achieved, thereby a basis for processing the task scheduling and system running core number/frequency is provided to the kernel space.
The foreground applications illustrated in the implementations of the present disclosure usually are run in the user space of the operating system, the foreground applications are those application relative to background applications, the foreground applications and background applications are applications running in the system currently, and applications displayed to the user and capable of being operated by the user currently are the foreground applications, the background applications are run in the background of the system. For example, a mobile terminal currently displays an application interface of a “Wechat®” application and runs a map application in the background simultaneously, therefore, the “Wechat®” application is the foreground application and the map application is the background application. In other explanations, the foreground applications are applications running in foreground of the terminal device, and the background applications are applications running in background of the terminal device.
At block S101, a request for synchronizing actions of applications to a kernel space of the operating system is received, the request includes action parameters of the foreground applications and/or background applications.
In some implementations, the applications may include foreground applications and/or background applications, namely, the applications may include at least one of the foreground applications and the background applications. In the present disclosure, the applications are illustrated as the foreground applications and/or background applications for example. Throughout the specification, the applications, the foreground applications and/or background applications may be considered as the same object.
The actions of the foreground applications and background applications of the user space usually are classified to: open-loop actions and close-loop actions. In detail:
A. Open-Loop Action.
For this action category, in software codes, there is no corresponding definite stop action, thereby an action prediction running time corresponding to the open-loop action is required, which will be sent to the kernel. The open-loop action usually has a fixed expiration time, the action is stopped automatically when an action execution time exceeds the expiration time. For example, the expiration time of a sliding operation action is 300 milliseconds, the user does not need to provide a signal for stopping the action, and the sliding operation action is stopped automatically when it has been triggered for more than 300 milliseconds.
The open-loop action may include an application launch action, a wake-up action, an animated picture switching action, a sliding operation action, a software download action, and other actions.
B. Close-Loop Action.
The close-loop actions are those actions whose certain action time cannot be predicated, for example, when installing a software, how long the software can be installed completely is not known. For this action category, in the software codes, there is a definite stop action to correspond, therefore, there is no necessary to send the action time. Although a certain stop time of the close-loop action is not known, there is also need to provide a longest expiration time to prevent the close-loop action from being incapable of stopping due to accident. Take the software installation action as example, a default longest expiration time is 5000 milliseconds, if canceling the action is not occurred within 5000 milliseconds, the action would be stopped automatically. If an operation of canceling the action is generated on one's own initiative within 5000 milliseconds, the action would be stopped immediately.
The close-loop action may include a software installation action, a software video capturing action, a photographing action, a video encoding action, a preview action, a video playback action, an audio playback action, an input and output action, and other actions.
The foreground application and the background application of the user space send the request for synchronizing their actions to the kernel space of the operating system, namely synchronize their actions to the kernel space. In the implementation, the synchronization of actions is controlled uniformly, and action synchronization requests of each foreground application and each background application are received or obtained. The request includes action parameters of the foreground applications and background applications, correspond to the open-loop action and the close-loop action, the action parameters include a preset expiration time, a stopping action, and a maximum value of the expiration time.
At block S102, action categories of the foreground applications and/or background applications are obtained and an action determination is carried out, according to the action parameters of the foreground applications and/or background applications.
Based on the action parameters of the foreground applications and background applications, the action categories of the foreground applications and background applications may be analyzed and the action determination may be carried out. For example, if the action parameters include a preset expiration time, then the action may be determined as the open-loop action, and then determining whether the action time exceeds to the preset expiration time, if yes, then the action may be determined as already be stopped, and then action determination results are obtained.
At block S103, results of the action categories and the action determination of the foreground applications and/or background applications are sent to the kernel space.
By sending the analyzed results of the action categories and the action determination of the foreground applications and background applications to the kernel space, thereby a basis for processing the task scheduling and system running core number/frequency is provided to the kernel space, thus enabling the kernel to match the run requirement of the foreground applications and the background applications precisely, and the performance problems (such as programs response slowly, stuck, etc) and power consume problems (such as the power consume of background applications are too much, insignificant background application are running continuously) will not be leaded to occur.

At block S206, action categories of the foreground applications and/or background applications are obtained and an action determination is carried, according to the action parameters of the foreground applications and/or background applications.
Based on the action parameters of the foreground applications and background applications, the action categories of the foreground applications and background applications may be analyzed and the action determination may be carried out. For example, if the action parameters include preset expiration time, then the action may be determined as the open-loop action, and then determining whether the action time exceeds to the preset expiration time, if yes, then the action may be determined as already be stopped, and then the results of the action determination are obtained.
