title: Android - Flip Animation not flipping smoothly
body: <p>I want to make my image to flip horizontally for 4 times, and at the same time scaling it down.</p>
  
  <p>I have the following code for flipping:</p>
  
  <pre><code>ObjectAnimator flipAnimation = ObjectAnimator.ofFloat(view, "rotationY", 0.0f, 1440f);
  flipAnimation.setDuration(4000);
  flipAnimation.start();
  </code></pre>
  
  <p>And I have the following code in scale_down.xml for scaling down:</p>
  
  <pre><code>&lt;scale
          android:duration="4000"
          android:fromXScale="1"
          android:fromYScale="1"
          android:pivotX="50%"
          android:pivotY="50%"
          android:toXScale="0.1"
          android:toYScale="0.1" &gt;
      &lt;/scale&gt;
  </code></pre>
  
  <p>However, when I run my app on emulator in eclipse, the flipping image shows an awkward effect. As you can see from the images, sometimes while flipping, one vertical side is longer than the other side, making a stretching effect, which is not what I want. Any helps to eliminate that effect?</p>
