Method for detecting whether current application positioned on foreground or not

Abstract

The invention discloses a method for detecting whether a current application is positioned on a foreground or not. The method comprises the following steps: performing counting processing on interface operation of a started application program by using a counting module; judging whether the application program operates on the foreground or on the background according to the counting. Particularly, when the interface of the application program finishes the creation and is visible on the screen, counting is performed and one is added by the counting module; when the interface of the application program is invisible on the screen and is not destroyed, counting is performed and one is subtracted by the counting module; when a counting value of the counting module is 0, the application program runs on the background; when the counting value of the counting module is not equal to 0, the application program runs on the foreground. The technical scheme of the invention has the beneficial effects that compared with a traditional detection method, the method disclosed by the invention has the characteristic of simple logic structure; system overhead is effectively reduced, and the running efficiency of the system and software is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for detecting whether a current application is in the foreground. Background technique [0002] At present, in the Android application development technology, many applications need to judge whether the application is in the foreground or the background to meet the business logic needs. For example, the instant messaging application needs to judge whether it is currently running in the background. If it is in the background, it needs to display the received message to In the notification bar, if you switch from the background to the foreground, you need to display the message in the foreground. There are also some video playback applications that need to automatically pause when switching to the background and automatically play when switching to the foreground. These all need to determine whether the application is In the foreground and background, and th...

[0012] This method needs to obtain all running applications for each judgment, which greatly increases the overhead of the system. When there are many applications opened by the system, the running speed of the system will decrease, especially for smart phones that have been used for a period of time. For mobile phones, due to the large number of temporary files in the system, when the system is judging the usage status of the application, the system will respond slowly or even crash
