Animate Native Fragments transitions( Not fragments from support libs)

• Use these if you are not using the support libs and are targeting API11 and up
• IMPORTANT : We are using Native fragments : android.app.Fragment;
• The general flow is the same with minor changes to what is done in support fragments
• Animations now live inside objectAnimator objects

    <set xmlns:android="http://schemas.android.com/apk/res/android" >
    <objectAnimator
        android:valueFrom="90" android:valueTo="0"
        android:valueType="floatType"
        android:propertyName="rotation"
        android:duration="500"/>
    <objectAnimator
        android:valueFrom="0.0" android:valueTo="1.0"
        android:valueType="floatType"
        android:propertyName="alpha"
        android:duration="500"/>
    </set>

• We stuff the fragment inside its container as follows:

           Fragment1 fragment =  new Fragment1();

            FragmentTransaction ft = getFragmentManager().beginTransaction();
            //Must be called first!
            ft.setCustomAnimations(R.animator.fragment_enter,
                    R.animator.fragment_exit,
                    R.animator.fragment_pop_enter,
                    R.animator.fragment_pop_exit);
            ft.add(R.id.fragment_container, fragment);
            ft.addToBackStack(null);
            ft.commit();
