What feature would you like to be added?

A context is lost due to GLSurfaceView, rather than OpenGL ES itself. In theory, it is possible to avoid GLSurfaceView but keep using OpenGL ES. In this case, we have to create a class inheriting SurfaceView and implement bunch of code which GLSurfaceView did.

Why is this needed?

We'd like to avoid context lost on Android apps.
