this.getWindow().getDecorView().invalidate();

      }
   }, 1000);

@Override

    super.onWindowFocusChanged(hasFocus);
    /* Workaround a probable Android bug with fullscreen activities:
     * on resume status bar hides and black margin stays, 
     * reproducible half of the time when coming back from lock screen
