Base class for Android activities that use the support library action bar features.
Extending ActionBarActivity (along with the Theme.AppCompat theme) allows an application running on API level 7 or higher to include an Action Bar (which is otherwise only available when targeting API level 11+).
Warning Since Android 6.0 ActionBarActivity is deprecated! You should use AppCompatActivity instead.
