title: How to change HomeAsUp indicator in new AppCompat Toolbar?
body: <p>I wanna change default ActionBar homeAsUp indicator (drawable) in my AppCompat Toolbar. How to achieve that?
  Only default arrow shows up.</p>
  
  <p>styles (same for other API's level):</p>
  
  <pre><code>&lt;style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
  
          &lt;!-- API 14 theme customizations can go here. --&gt;
          &lt;item name="android:windowActionBarOverlay"&gt;true&lt;/item&gt;
          &lt;item name="android:homeAsUpIndicator"&gt;@drawable/home&lt;/item&gt;
  
          &lt;!-- Support library compatibility --&gt;
          &lt;item name="windowActionBarOverlay"&gt;true&lt;/item&gt;
          &lt;item name="homeAsUpIndicator"&gt;@drawable/home&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Toolbar in my fragment layout:</p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
          xmlns:android="http://schemas.android.com/apk/res/android"
