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