Step 104: and distributing a corresponding rendering area for each rendering subtask application.
In practical application, the LocalSurface encapsulates a drawing Surface texture (Surface texture) and a drawing Surface (Surface), and the Surface is a drawing Surface of an android system. LocalSurface is an area that can be internally generated or externally injected to directly render images or create rendering environments. In practical application, each rendering subtask corresponds to a LocalSurface.
Specifically, allocating a corresponding rendering area for each rendering subtask application includes:
starting a rendering thread in response to the image rendering request;

and the rendering thread allocates a corresponding rendering area for each rendering subtask.
The rendering thread is specifically a computer thread used for rendering and generating an image, the thread is a minimum unit which can be operated and scheduled by an operating system, and the rendering thread is used for generating a rendering image corresponding to the image rendering request.
After each rendering subtask is determined, a LocalSurface corresponding to each rendering subtask is applied to a rendering thread according to each rendering subtask, and the rendering thread allocates the LocalSurface to each rendering subtask according to the application, that is, a corresponding memory area is allocated to each rendering subtask in a memory.

Step 106: and generating a sub-view corresponding to each rendering subtask in each rendering area.
