Animate the transition between fragments

by

I’m trying to animate the transition between fragments. I got the answer from the following
Android Fragments and animation 

FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);

DetailsFragment newFragment = DetailsFragment.newInstance();

ft.replace(R.id.details_fragment_container, newFragment, "detailFragment");

// Start the animated transition.
ft.commit();

And my R.anim.slide_in_left 

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromXDelta="50%p" android:toXDelta="0"
            android:duration="@android:integer/config_mediumAnimTime"/>
       <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

But when I tried this it showed 

02-08 16:27:37.961: ERROR/AndroidRuntime(1717): FATAL EXCEPTION: main

Any ideas? When I checked Honeycomb API reference translate is there. What did I miss?
Is there any other way to animate the transition between fragments?
Thank you
