A method for dynamically switching software rendering and hardware rendering of an android display system

Abstract

The invention relates to a display frame of an Android operation system, in particular to an Android display system software drawing and hardware drawing dynamic switching method. In an existing Android display system, a P31 system running monitoring service ROS is additionally arranged for monitoring and collecting the system running state, and then a drawing method used in the P4 is judged according to the state; a P32 application program drawing control interface ADI is additionally arranged, the mode used for self drawing can be set for an application program in a forced mode through the interface, and the priority set in the mode is larger than P31. By means of the Android display system software drawing and hardware drawing dynamic switching method, some old application programs can smoothly run on many platforms, and the user experience is good; the high fault tolerance of is achieved when the display frame is applied in the drawing process, and more application programs can run on lower-allocation platforms.

Description

technical field [0001] The invention relates to the display frame of the android operating system. Specifically, the invention is based on the android display framework, and provides a method for dynamically switching the android software display (using CPU for drawing) and hardware display (using GPU for drawing). Background technique [0002] Starting from Android 3.0, the Android 2D drawing process is designed to support hardware acceleration. With this hardware acceleration, the drawing operations performed by the application on the drawing interface will use the hardware to render and draw, which greatly optimizes the display speed and user experience. [0003] Hardware drawing is characterized by fast drawing speed, smooth interface, and good user experience, but consumes hardware resources, causing some applications to fail to run on low-configuration devices. In addition, hardware drawing cannot satisfy all drawing methods (depending on the functions provided by the...

Problems solved by technology

[0014] When the application program initializes the graphical interface, P4 will check whether the current application program contains hardware acceleration flags (since this flag is only supported after Android 3.0 , so the application compiled with the SDK before android3.0 does not contain this flag) to determine whether the graphics drawing library used is software or hardware. Once the decision is made, the corresponding resources are immediately applied for, and cannot be changed later

It can be seen that the way an application is displayed on the Android platform is completely determined by the version of the application, and the system cannot intelligently handle it.

[0015] As mentioned above, in order to have good compatibility, Android's display system includes both hardware rendering and software rendering, but whether an application uses hardware rendering or software rendering is determined by the application at the time of initialization. It cannot be changed, so the applications released based on the SDK before Android 3.0 do not have the hardware acceleration flag, so they cannot enjoy the hardware acceleration feature when running on a platform that supports hardware acceleration; the applications released based on the SDK after Android 3.0 , and because it cannot be dynamically switched, the effect of running on some platforms with poor hardware (mainly GPU) is not good, and it may even fail to run
