Creating a 3D flip animation in Android using XML

I have created a 3D flip of a view using this android tutorial
However, I have done it programmatically and I would like to do it all in xml, if possible. I am not talking about simply shrinking a view to the middle and then back out, but an actual 3D flip.

Is this possible via xml?

Here is the answer, though it only works with 3.0 and above.

1) Create a new resources folder called "animator".

2) Create a new .xml file which I will call "flipping". Use the following xml code:

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:valueFrom="0" android:valueTo="360" android:propertyName="rotationY" >

No, the objectAnimator tags do not start with an uppercase "O".

3) Start the animation with the following code:

ObjectAnimator anim = (ObjectAnimator) AnimatorInflater.loadAnimator(mContext, R.animator.flipping); 
anim.setTarget(A View Object reference goes here i.e. ImageView);

I got all this from here.
