title: Android objectAnimator animate backgroundColor of Layout
body: <p>I have a problem. I want to <strong>animate the background color</strong> of a <code>LinearLayout</code>, using <code>ObjectAnimator</code>. <br>The problem is that it animates, but it does neither care about duration nor <code>valueFrom</code> and <code>valueTo</code>. </p>
  
  <p>This is my xml file:</p>
  
  <pre><code>&lt;objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
      android:duration="2000"
      android:propertyName="backgroundColor"
      android:repeatCount="infinite"
      android:repeatMode="reverse"
      android:valueFrom="#FF0000"
      android:valueTo="#000000" /&gt;
  </code></pre>
  
  <p>In Java I call like this:</p>
  
  <pre><code>ObjectAnimator objAnim = (ObjectAnimator)AnimatorInflater.loadAnimator(getActivity(), R.animator.animator_bkg);
  objAnim.setTarget(view);
  objAnim.start();
  </code></pre>
  
  <p>Note that when I animate the alpha of the layout, it works as expected. <br>Is this an Android bug (4.0.3 on Asus Transformer), or I miss something?</p>
