title: Android (3.0) Action Bar dont want to Go
body: <p>I am working with XOOM and trying to hide action bar. So i follow the instruction did the following
  in manifest file:</p>
  
  <p><code>
  uses-sdk android:minSdkVersion="11" android:targetSdkVersion="11"
  </code></p>
  
  <p>also set activity theme.</p>
  
  <p><code>
  android:theme="@android:style/Theme.Holo.NoActionBar"
  </code></p>
  
  <p>unfortunately i can still see the action bar. so i remove the holo action part from my manifest and added following code</p>
  
  <p><code>
  ActionBar actionBar = getActionBar();
          actionBar.hide();
  </code></p>
  
  <p>getting null pointer exception from hide() method. so i understand getActionBar() is returning null. Now i am curious what i am missing? </p>
