Catch the end of Return Activity Transition
<p>From Activity <strong>A</strong> to <strong>B</strong> , I set enter and return transitions.
I want to put a fadein animation after the  return transition ( <strong>B</strong> to <strong>A</strong> after a back).</p>

<p>Originally , I thought that in Activity's onStart method will a good place.
It turns out I don't see the fadein animation so I suppose the ending of the Return Transition happens after <strong>onStart()</strong></p>

<p>I checked with <a href="https://developer.android.com/reference/android/app/SharedElementCallback.html" rel="nofollow">SharedElementCallback</a> but it doesn't tell when the transition ends.</p>

<p>How to catch the moment when the Return Transition ends ?</p>
