title: App crashing when trying to hide the title bar
body: <p>In order to make a full screen app, I've done the following changes to the manifest of a new "blank activity" project:</p>
  
  <pre><code>  android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
  </code></pre>
  
  <p>The application crashes when running on any device. The changes I've made have been recommended by many posts here in StackOverflow and I couldn't figure out what I've done wrong.</p>
