title: ActionbarSherlock doesn't appear
body: <p>I'm having problem with ActionBar Sherlock (latest version), after successful compilation I don't see ActionBar in app. Just black screen and default TextView... 
  Before I've a problem with install libraries, but after added Support Library to ActionBarSherlock I can built it. </p>

  }
  </code></pre>
