title: Action bar compatibility
body: <p>I notice that on the android developer web page, there is <a href="http://developer.android.com/resources/samples/ActionBarCompat/index.html">THIS</a> document which is titled "<strong>Action bar compatibility</strong>" .</p>
  
  <p>Does it show the action bar implementation with <strong>old</strong> android API <strong>less than</strong> v11 or does it show how to implement action bar with API v11 and greater? I get confused by this page. </p>
