If you render the Open GL graphics in the main thread (where user- input is received and handled), how are you going to program animated graphics when the user does not interact with the screen/keyboard at all? by issuing a log of handler.post(Runnable) commands ?
Also, your sample code is simple and it's therefore rendered pretty fast. If you start adding many more vertices, adding textures, lighting models, etc, the rendering will slow down. In short, i strongly suggest seperating the user-input(=main) thread and the Open GL drawing code into a seperate thread. It'll keep your app performance predictable and, in the end, better maintainable.
