TestLatencyView

public class TestLatencyView extends android.opengl.GLSurfaceView
An implementation of SurfaceView that uses the dedicated surface for displaying an OpenGL animation. This allows the animation to run in a separate thread, without requiring that it be driven by the update mechanism of the view hierarchy. The application-specific rendering code is delegated to a GLView.Renderer instance.
