title: android actionbar oncreateoptionsmenu not called
body: <p>in my app I can see the actionbar, but I can't see the setting items, because it never call  onCreateOptionsMenu.</p>
  
  <p>The app if for target sdk 16, it's composed by a tab and each tab is a fragment. 
  On the Fragment class, during the onCreate() I'm calling setHasOptionsMenu(true).
  The theme is Theme.Holo.Light.
  If I run the app on the emulator (Android 4.0) and I press the hardware menu item, it calls the method, but it shows me the menu like the Android 2.3 menu, not in the actionbar!!</p>
  
  <p>I don't think the problem is on the sdk version, because the actionbar is visible!
  Any idea? what I could check to find the error?</p>
  
  <p>Thanks a lot for every help!
  My best regards
  Manuela</p>
