title: How can I use VectorDrawable with the Android Toolbar?
body: <p>What is the proper method to use the new VectorDrawable in the toolbar?</p>
  
  <p>I tried to use the <code>app:srcCompat</code> element as illustrated below, but nothing showed up.</p>
  
  <pre><code>&lt;menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
    &lt;item
      app:srcCompat="@drawable/ic_clear"
      app:showAsAction="ifRoom" /&gt;
  &lt;/menu&gt;
  </code></pre>
  
  <p>I have my own toolbar layout using <code>android.support.v7.widget.Toolbar</code> and Android Support Library v23.2 on JB (16).</p>
