title: use of syncState() in ActionBarDrawerToggle
body: <p>I'm using <code>ActionBarDrawerToggle</code> class to tie together the functionality of <code>DrawerLayout</code> and the framework <code>ActionBar</code> to implement the recommended design for navigation drawers.  </p>
  
  <p>What Android developer site says is:</p>
  
  <blockquote>
    <p>Call syncState() from your Activity's onPostCreate to synchronize the indicator with the state of the linked DrawerLayout after onRestoreInstanceState has occurred.  </p>
  </blockquote>
  
  <p>But I'm not getting what <code>syncState()</code> method actually does?  </p>
  
  <p>Please explain it as simple as possible.</p>
