Android : Use OpenGL To Make Bitmap Without GLSurfaceView?

I would like to be able to use OpenGL in the Android to render into a bitmap (or any other sort of buffer I can turn into one), without actually displaying a GLSurfaceView.

The purpose is to dynamically create very complex images using OpenGL, and then drawing those images on the canvas of a MapView.

I have tried overlaying a translucent GLSurfaceView over a MapView, my preferred approach, but it has some problems:

1) I have complex menus I need to display from either the MapView or the GLSurfaceView. I have been doing this using a ListView with its own activity. Unfortunately, that activity pushes the MapView down the stack. The result is a bit of flickering when the ListView activity finishes, popping the MapView back to the top. Even worse, if I use the ListView to overlay the GLSurfaceView (giving it the same complex menu capabilities), when it finishes, the GLSurfaceView reappears but the MapView doesn't display.

2)As soon as the GLSurfaceView is created, the MapView stops fetching and rendering tiles. There seems to be no way to know when the MapView is complete, so I have to delay an arbitrary interval before creating the surfaceview.

3) When the GLSurfaceView is present, the MapView's built-in user interface functions are obscured.

Anyone know if there is a way around any of these problems?
