title: How to add "menu" indicator next to Action Bar's app icon?
body: <p>At least Gmail and Youtube Android apps use a side menu (<a href="http://developer.android.com/training/implementing-navigation/nav-drawer.html" rel="nofollow noreferrer">navigation drawer</a>?) that opens by swiping, or by clicking the app icon (home button):</p>

  <p>Is the menu indicator / icon in the screenshot above a ready-made part of Android SDK? (Or a custom icon Google uses in their apps?) In any case, <strong>what's the easiest way to get your home button to look like that</strong>, i.e., like it opens a menu?</p>
  
  <p>(<code>targetSdkVersion</code> 18; <code>minSdkVersion</code> 14)</p>
  
  <h2>Resolution</h2>
  
  <p>Finally <a href="https://stackoverflow.com/a/19724694/56285">got it working</a>. What was missing for me was 1) <a href="http://android-ui-utils.googlecode.com/hg/asset-studio/dist/icons-nav-drawer-indicator.html" rel="nofollow noreferrer">the actual icon</a> and 2) deferred call to <code>syncState()</code> on the <code>ActionBarDrawerToggle</code>.</p>
