title: ActionbarSherlock and homeAsUpIndicator
body: <p>I have the problem to customize the back arrow. I want a red arrow instead of default arrow. I've read many topics about that but it doesn't work.</p>
  
  <p>So i place my styles in res/values/styles.xml. Here is my code :</p>
  
  <pre><code>&lt;style name="AppBaseTheme" parent="Theme.Sherlock.Light"&gt;
  
      &lt;item name="actionBarStyle"&gt;@style/Widget.AppTheme.ActionBar&lt;/item&gt;
      &lt;item name="homeAsUpIndicator"&gt;@drawable/btn_nav_retour&lt;/item&gt;
  
  &lt;/style&gt;
  </code></pre>
  
  <p>I can't set "android:homeAsUpIndicator" beacause it requires api level 11 and my min sdk is 9.</p>
  
  <p>Should I set the same code in res/values-v11/styles.xml ?</p>
  
  <p>Thx</p>
