There is also a XML way that Google recommends    lt LinearLayout     android orientation  vertical      android layout width  fill parent      android layout height  fill parent      android keepScreenOn  true  gt    Check Google Slides - Slide 16       Wakelocks are costly if forgotten       Consider using   android keepScreenOn to ensure correctness

In a View  in my case a SurfaceView subclass  you can set the screen on always on  I wanted the screen to stay on while this view was still drawing stuff    public class MyCoolSurfaceView extends SurfaceView     Override protected void onAttachedToWindow         super onAttachedToWindow        this setKeepScreenOn true       Override protected void onDetachedFromWindow        super onDetachedFromWindow        this setKeepScreenOn false
