title: Hiding navigation bar shadow
body: <p>I want to make my app fullscreen. I added this code to onCreate method of activity class.</p>
  
  <pre><code>    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
      getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
  </code></pre>
  
  <p>However a shadow appears in place of navigation bar. How can I remove that shadow?</p>
