title: hide the navigation bar "more" button at the bottom of the screen on Android
body: <p>On my application, I have, on some devices (such as the HTC One) a bar containing only the "More" button (e.g : three vertical dots). Example below with the Amazon app that gets the same behavior.</p>
  
  <p><img src="https://i.stack.imgur.com/XcykH.jpg" alt="Three dots appear "></p>
  
  <p>I tried to remove it, by adding this on my manifest :</p>
  
  <pre><code>&lt;application
  android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" &gt; &lt;/application&gt;
  </code></pre>
  
  <p>It didn't work. I also tried to change the visibility of the displayed view :</p>
  
  <pre><code>View v = this.findViewById(android.R.id.content);
  v.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
  </code></pre>
  
  <p>But it only works when displaying the activity. When I interact on my view, the navigation bar reappers.</p>
  
  <p>I noticed that this navigation bar does not appear on a Galaxy S III nor on a Galaxy S II. Can this navigation bar only be displayed only because of the large resolution of the HTC One screen ?</p>
  
  <p>Is there any way to remove this bar only when it appears ?</p>
