Fragment transaction custom animation - Android
<p>I am trying to do: 
<code>ft.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);</code></p>

<p>But I am getting an exception with Unknown animation name: objectAnimator - see details below:</p>

<pre><code>04-08 10:45:41.637: ERROR/AndroidRuntime(1222): FATAL EXCEPTION: main
04-08 10:45:41.637: ERROR/AndroidRuntime(1222): java.lang.RuntimeException: Unknown animation name: objectAnimator

04-08 10:45:41.637: ERROR/AndroidRuntime(1222):     at android.view.animation.AnimationUtils.loadAnimation(AnimationUtils.java:72)
</code></pre>

<p>Why is there an error? I am not sure how to solve it. Please Help. Thanks.</p>

<p>FYI: My min sdk is 7, but I am build for sdk 11 with compatibility library.</p>
