title: Android - Navigation drawer with menu icon instead of back button
body: <p>I'm starting learning android and when I created my app I chose the Navigation Drawer template and here is the problem:</p>
  
  <p>1) Even though I'm at the homepage the back button is displayed, and it opens the menu </p>
  
  <p>2) I'd like to have a menu icon in every single page and let the hardware back button handle the intent history</p>
  
  <p>So basically I'd like to know how to change back button icon to menu icon.</p>
  
  <p>code: (onCreateOptionsMenu)</p>
  
  <pre><code>ActionBar actionBar = getActionBar();
  actionBar.setDisplayHomeAsUpEnabled(true);
  actionBar.setHomeButtonEnabled(true);
  </code></pre>
  
  <p>I can show/hide the back button but I can't figure out where it's calling the icon itself</p>
  
  <p>Sorry if it's a silly question but I didn't find good answers to this (on ly this link: <a href="https://developer.android.com/training/implementing-navigation/nav-drawer.html" rel="nofollow">https://developer.android.com/training/implementing-navigation/nav-drawer.html</a>)</p>
