Problems solved by technology

[0003] However, when the existing technology manages application scenarios such as the task manager and the Home desktop application under the Android platform, only the application screens running in the background can be obtained, and the screens of all historical applications cannot be read. Switching applications makes the UI less room to play when switching applications, the display is not intuitive, and the user experience is poor

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Before introducing the application screenshot method provided by the present invention, the basic knowledge of the present invention is briefly introduced:

[0024] Activity is a standard component of the Android platform. In fact, an Activity is a single screen in the application, which inherits from the Activity class, and it will display the UI composed of Views and respond to events.

[0025] History Activity is a historical activity, which refers to the activity that the user has opened, including the activity that is running in the background task.

[0026] SurfaceView is a special View view class of the Android platform. It is the parent class of the two 3D view classes GLSurfaceView and RSSurfaceView. Both 3D view cla...

Abstract

The invention discloses an application screen capture method and device for a mobile terminal, and belongs to the field of mobile terminals. The method comprises the steps of receiving a switching order which is used for switching a designated application of the mobile terminal to the background for operation, capturing a designated area of the application screen of the designated application to obtain a captured picture of the designated area, and storing the captured picture of the designated area, and switching the designated application to the background for operation. According to the method and device, before application screen Activity is turned off and when an Activity window can still be seen, the application screen is subjected to screen capture, the last real screen of the Activity is obtained, the problem of high memory usage due to the fact that screen capture is carried out after the application screen is turned off is avoided, screen capture efficiency is improved, and memory usage and calling frequency are lowered.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and device for taking screenshots of application screens of mobile terminals. Background technique [0002] With the development of mobile terminals, as an example of mobile terminals, Android systems are often installed on smartphones. Android is a software platform open sourced by Google for developing mobile programs. It includes operating systems, middleware and some key applications. The mobile terminal user switching activity (Activity) is a standard component of the Android platform. In fact, an Activity is a single screen in the application, which inherits from the Activity class, and it will display the UI (User Interface, user interface) composed of Views and respond to events. [0003] However, when the existing technology manages application scenarios such as the task manager and the Home desktop application under the Android platform, only the applic...
