25 /**
26  * This sample shows you how to use ActionBarCompat with a customized theme. It utilizes a split
27  * action bar when running on a device with a narrow display, and show three tabs.
28  *
29  * This Activity extends from {@link ActionBarActivity}, which provides all of the function
30  * necessary to display a compatible Action Bar on devices running Android v2.1+.
31  *
32  * The interesting bits of this sample start in the theme files
33  * ('res/values/styles.xml' and 'res/values-v14</styles.xml').
34  *
35  * Many of the drawables used in this sample were generated with the
36  * 'Android Action Bar Style Generator': http://jgilfelt.github.io/android-actionbarstylegenerator
