surfaceView.setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY)For developers wishing to display OpenGL rendering, when choosing the rendering mode with GLSurfaceView#setRenderMode(int renderMode), using RENDERMODE_WHEN_DIRTY instead of RENDERMODE_CONTINUOUSLY (by default) can improve battery life and overall system performance by allowing the GPU and CPU to idle when the view does not need to be updated.
