Remove the lines above. Any use of GLSurfaceView in this is wrong.

You are supposed to return an instance of your subclass of GLEngine
here, "new CubeEngine()" in your case.

You should be implementing GLWallpaperService.Renderer, not
GLSurfaceView.Renderer.

Remove all of the above.

>mGLSurfaceView.setRenderMode(RENDERMODE_CONTINUOUSLY);
These should be called on GLEngine, which you are subclassing. They
should look like this:
setRenderer(new OpenGLRenderer());
setRenderMode(RENDERMODE_CONTINUOUSLY);

Remove all of the above.
