Custom Flip animation between fragments android support package

Question

I am trying to find out how to create flip animation between 2 fragments.

I have tried the CardFlip training as a guide, but don't seem to be able to achieve it. I am using the android support package and set it to tween animation, but not successful.

How to implement flipping animations between fragment?

here is the first 2 xml i created from the guide, maybe you could see if am doing something wrong. screen_flip_left_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

     <!-- Before rotating, immediately set the alpha to 0. -->
    <alpha
        android:valueFrom="1.0"
        android:valueTo="0.0"
        android:propertyName="alpha"
        android:duration="0" />

    <!-- Rotate. -->
    <rotate
        android:valueFrom="-180"
        android:valueTo="0"
        android:propertyName="rotationY"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:duration="@integer/card_flip_time_full"/>

    <!-- Half-way through the rotation (see startOffset), set the alpha to 1. -->
    <alpha
        android:valueFrom="0.0"
        android:valueTo="1.0"
        android:propertyName="alpha"
        android:startOffset="@integer/card_flip_time_half"
        android:duration="1" />
</set>

screen_flip_left_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
        <!-- Rotate. -->
    <rotate
        android:valueFrom="0"
        android:valueTo="180"
        android:propertyName="rotationY"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:duration="@integer/card_flip_time_full" />

    <!-- Half-way through the rotation (see startOffset), set the alpha to 0. -->
    <alpha
        android:valueFrom="1.0"
        android:valueTo="0.0"
        android:propertyName="alpha"
        android:startOffset="@integer/card_flip_time_half"
        android:duration="1" />

</set>

android:propertyName is only for ObjectAnimator (Honeycomb+) animations, not view animations from Gingerbread. A card flip animation is only possible using Honeycomb animator api's. I created a fork of the support library to allow using Animator apis from NineOldAndroids for fragment transitions. Use the animator-transition branch of my github project. Once you have the modified support library look at http://developer.android.com/training/animation/cardflip.html to make the animator xml.
