title: Can't change drawer icon for NavigationDrawer
body: <p>I'm trying to implement the new <code>NavigationDrawer</code> provided since the last Android keynote.</p>
  
  <p>I got everything up and running, the navigation drawer opens and closes when pressing on the icon on the top left corner.</p>
  
  <p>But now I still have the arrow icon although I replaced it with the ic_drawer from Android.  Why?</p>
  
  <p>Here's my code where I specified the icon:</p>
  
  <pre><code>mDrawerToggle = new ActionBarDrawerToggle(
              this,                 
              mDrawerLayout,         
              R.drawable.ic_drawer, //&lt;-- This is the icon provided by Google itself
              R.string.drawer_open,
              R.string.drawer_close 
              )
  </code></pre>
  
  <p>But the application still runs with the standard icon of <code>setDisplayHomeAsUpEnabled</code>.</p>
  
  <p>Any ideas?</p>
