title: Add NavigationDrawer toggler by replacing back navigation in action bar
body: <p>I have an activity in my app which is not launcher.
  I want to add a navigation drawer with toggler. I tried following the instructions here <a href="http://developer.android.com/training/implementing-navigation/nav-drawer.html#ActionBarIcon" rel="nofollow">http://developer.android.com/training/implementing-navigation/nav-drawer.html#ActionBarIcon</a></p>
  
  <p>But my back navigation still shows up (It exits the app as I have added appropriate flags to the intent)
  How can I show the drawer toggler icon ?</p>
  
  <p>Also android.support.v4.app.ActionBarDrawerToggler is deprecated, what should I use instead ?</p>
