Mobile terminal and method for processing pictures

Abstract

The invention discloses a mobile terminal and a method for processing pictures. The mobile terminal comprises a list acquisition module, a detection module, an information acquisition module and a processing module; the list acquisition module is used for acquiring a multi-task cache picture list when multi-task cache pictures need to be displayed; the detection module is used for detecting whether a blank screen picture exists in the obtained multi-task cache picture list or not; when it is detected that the blank screen picture exists in the obtained multi-task cache picture list, the information acquisition module is notified; the information acquisition module is used for receiving a notice from the detection module and obtaining application information corresponding to the blank screen picture; the processing module is used for generating a picture corresponding to the application information and replacing the blank screen picture with the generated picture in the obtained multi-task cache picture list. According to the mobile terminal and the method for processing the pictures, the problem that the multi-task cache pictures are blank screen pictures is avoided, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to smart terminal technology, especially a mobile terminal and a method for processing pictures in multitasking. Background technique [0002] With the continuous development of science and technology, a user can start or end an application (APP) through a graphical multitasking management system (hereinafter referred to as "multitasking") of a mobile terminal, and can also clear multiple applications at the same time. Multitasking is to capture the last screen display information of the application in the foreground when the background application retreats from the foreground to the background, and cache the captured screen display information in the form of pictures (called cached pictures). When the user uses When multitasking, the multitasking will read the cached image of the application from the cache for display. [0003] However, when the user uses multitasking, the cached pict...

Problems solved by technology

[0003] However, when users use multitasking, they will encounter the problem that the cached pictures in the multitasking cached picture list are black screens (or black screen pictures), and the user experience is extremely bad.

Among them, there are several reasons why the cached picture in the multitasking cached picture list is a black screen: First, it is caused by problems in the Android (Android) system itself, such as: multitasking screenshots will screenshot the fixed window level, when the window level changes When the content cannot be intercepted, it will cause a black screen; secondly, because the interface management server (AMS, ActivityManagerService) design does not consider many abnormal situations, because some applications will trigger AMS errors (bugs) when they exit the interface continuously. As a result, AMS will not request screenshots, which will eventually lead to a black screen when multitasking screenshots are taken; finally, due to the safety considerations of the application itself, the system is not allowed to take screenshots, and multitasking will replace the current page with the historical cached pictures of the application. Newly installed apps don't have a history cache image, so they get a black screen
