title: Actionbar not shown with AppCompat
body: <p>I am backporting my app to API7 with AppCompat and have a problem with the actionbar.</p>
  
  <p>When I use <code>FragmentActivity</code> the actionbar is shown on my phone (API18), but with <code>ActionBarActivity</code> it shows up as the optionmenu by pressing the menubutton.</p>
  
  <p>On the emulator with API7 the actionbar is always shown as an optionsmenu.</p>
  
  <p>Any ideas?</p>
