Android FragmentTransition Sample
===================================

This sample demonstrates how to start a Transition after a Fragment Transaction.

Introduction
------------

This sample uses [the Transition framework][1] to show a nice visual effect on
Fragment Transaction.

Animation for fragment _transaction_ can be customized by overriding
[onCreateAnimation][2]. In this sample, we set up an AnimationListener
for this Animation, and start our Transition on [onAnimationEnd][3].

Transition is started by calling [TransitionManager.go][4]. We don't
instantiate a Scene for the initial state of Transition, as we never
go back. One thing we need to be careful here is that we need to
populate the content of Views after starting the Transition.
