title: ActionBar Compat ActionBarActivity setTitle does not work in Android 2.X
body: <p>My question is same as <a href="https://code.google.com/p/android/issues/detail?id=58982" rel="noreferrer">this issue</a>.</p>
  <p>I've setup the Android Support Library by following <a href="http://developer.android.com/tools/support-library/setup.html" rel="noreferrer">this instruction</a>. (I'm using Support Library, revision 19.0.1)</p>
  <p>In this issue, the google's staff said &quot;this is fixed in the Support Library v19&quot;. However, it does not work in my device(Gingerbread).</p>
  <p>I've tried to find solution, but I couldn't find that. Any ideas?</p>
