title: how do you remove the navigation bar on Android?
body: <p>When I listen to a YouTube video fullscreen in landscape on my Galaxy Nexus, the navigation bar on the right disapear after a few seconds (the bar which contains the &quot;back&quot;, &quot;home&quot; and &quot;recent apps&quot; buttons ).</p>
  <p>I want to do the same thing when a user watch a video in my app. What is the code to hide the navigation bar?</p>

  <p>[UPDATE] Here is the bar I want to hide. Not the title bar, nor the action bar. The navigation bar. (the bar which contains the &quot;back&quot;, &quot;home&quot; and &quot;recent apps&quot; buttons ). I also don't want to &quot;dim&quot; the buttons. I'm looking into removing the bar entirely (like the YouTube app does when you plan a video fullscreen in landscape mode)</p>
