title: Expected resource of type animator [ResourceType]
body: <p>I've updated my SDK to the newest version, but now I am getting a lint error.</p>
  
  <blockquote>
    <p>Error: Expected resource of type animator [ResourceType]</p>
  </blockquote>
  
  <p>The error occurs on this line:</p>
  
  <pre><code>AnimatorInflater.loadAnimator(context, R.anim.right_slide_in)
  </code></pre>
  
  <p>The referenced resource <code>/res/anim/right_slide_in.xml</code> looks like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
      android:interpolator="@android:anim/linear_interpolator"
      android:valueTo="0"
      android:valueFrom="1.0"
      android:propertyName="xFraction"
      android:valueType="floatType"
      android:duration="450" /&gt;
  </code></pre>
  
  <p>It always worked before. Could somebody explain why I am getting that error?</p>
