title: Displaying card flip animation on old android
body: <p>We all know this <a href="http://developer.android.com/training/animation/cardflip.html" rel="nofollow noreferrer">article</a> of how to create <code>&quot;card filp&quot;</code> animations using <code>new api</code>.
  But how can I make this <code>on apis &lt; 3.0</code>?</p>
  <p><em>Update:</em></p>
  <p>As long as there are good and easy-to-use libraries like <a href="https://github.com/emilsjolander/android-FlipView" rel="nofollow noreferrer">android-FlipView</a> I don't think you really need to do such animation by yourself.</p>
