GLSurfaceView as Texture

I've been trying to render a GLSurfaceView on the surface of a OpenGL Cube as a Texture. Is it possible? How to go about it?

The usual approach is to render to a framebuffer object (FBO) backed by a texture, and then render from that.

You can google for examples of FBO usage in GLES2 (the setup is a bit complicated). One example showing it in practice is the "record GL app" activity in Grafika, which is using FBOs (and a couple of other approaches) to record GLES rendering. The last "else" clause in doFrame() renders to an FBO, then renders that texture twice, once on-screen, once to a video recorder.

You may want to switch from GLSurfaceView to plain SurfaceView to get more control over the rendering process. Most of the code in Grafika uses SurfaceView or TextureView.
