title: Data Binding with srcCompat
body: <p>I'm using the new vector drawable support in Support Lib v23.2 with app:srcCompat &amp; trying to set its drawable via data binding.</p>
  
  <pre><code>&lt;layout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
  
  &lt;data&gt;
      &lt;variable
          name="mediaPojo"
          type="in.ishaan.pika.data_binding.MediaPojo"/&gt;
  &lt;/data&gt;
  
  &lt;RelativeLayout
      android:background="@color/black"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;VideoView
          ... /&gt;
  
      &lt;ImageView
          ...
          app:srcCompat="@{mediaPojo.isPlaying ? @drawable/ic_pause_24dp : @drawable/ic_play_arrow_24dp}"
      /&gt;
  
      &lt;ProgressBar
          .../&gt;
  &lt;/RelativeLayout&gt;
  &lt;/layout&gt;
  </code></pre>
  
  <p>On trying to build, studio throws:</p>
  
  <blockquote>
    <p>Error:(33, 30) Cannot find the setter for attribute 'app:srcCompat' with parameter type android.graphics.drawable.Drawable.</p>
