title: Why has TabListener been deprecated?
body: <p>In Android 5 (API level 21) the <a href="http://developer.android.com/reference/android/app/ActionBar.TabListener.html">ActionBar.TabListener</a> has been deprecated. Why? What are we supposed to use instead? Does this mean that action tabs as a UI element have been deprecated in general or is there a new way to implement them?</p>
