title: Why android:actionBarDivider doesn't work?
body: <p>Having</p>
  
  <pre><code>&lt;item name="android:actionBarDivider"&gt;@drawable/action_bar_divider&lt;/item&gt;
  </code></pre>
  
  <p>in my Activity style has zero effect. Doesn't matter if I'm using native ActionBar or ActionBarSherlock. Why?</p>
