Create a pair of Flip Animation that can be used to flip 3D transition from fromView to toView .

     * 
     * NOTE: Avoid using this method. Instead, use {@link #flipTransition}.

     *            the transition duration in milliseconds

     *            {@link AccelerateInterpolator} interpolator)
