GLSurfaceView - how to make translucent background

Question

I try to render using GLSurfaceView, and by docs I set format:

getHolder().setFormat(PixelFormat.TRANSLUCENT);

The I use GLSurfaceView.Rend

Answer 1

try using setZOrderMediaOverlay(true) for the GLSurfaceView with Hardware Acceleration for the Activity set to false. That makes the GLSurfaceView background Transparent. But I am not sure how the hardware acceleration impacts it.
Overlaying a GLSurface on top of a MapView without using SetZOrderTop.
I had posted a question recently still looking for a better solution
