Ah, I didn't realize how you were initializing GL. I'm bad at the EGL config stuff which is why I just use GLSurfaceView. I'm wondering if your problem is there? Consider trying GLSurfaceView and let me know the results. Otherwise, you may want to debug your init to make sure that it's correctly initializing a GL context and surface on the device.
