Android - Custom Animation on fragment transaction not running

I'm using Google API 8 (Android 2.2) with support package v4.

It doesn't give any error or animation.

Transaction:

FragmentTransaction transaction = manager.beginTransaction();       
transaction.replace(R.id.content, myFragment);
transaction.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
transaction.commit();

Animations:

slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <translate
        android:duration="700"
        android:fromXDelta="-100%"
        android:toXDelta="0%" >
    </translate>
</set>

slide_out_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="700"
        android:fromXDelta="0%"
        android:toXDelta="100%" >
    </translate>
</set>

Does anyone know what is happening here?

The manager was stacking my transaction before I set the animation, so it stacks the transaction without animations (sad but true), and that occurs even if I commit the transaction after the setCustomAnimations().

The solution is to set the animations first:

FragmentTransaction transaction = manager.beginTransaction();       
transaction.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
transaction.replace(R.id.content, myFragment);
transaction.commit();

As suggested above, separate statements will definitely work. But the trick here is to setCustomAnimation before setting transaction type viz.add, replace, etc. else it doesn't. So, applying the same logic, method chaining also works. eg.

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations(R.anim.a_slide_up,
                             R.anim.a_slide_down,
                             R.anim.a_slide_up,
                             R.anim.a_slide_down)
        .add(R.id.root_layout, 
             MyFrag.newInstance())
        .addToBackStack("MyFrag")
        .commit();

Putting it here, so that someone who prefers method chaining finds it helpful. Cheers!
