This is a regression where we changed the source view for the transition to dummy view, but since it was not yet attached, it could not get the handler implicitly to post the onAnimationCompleted callback. This CL modifies these ActivityOption transitions to also take an explicit handler to process the callback on. Bug: 18784289 Change-Id: I73f745c33b9f8aed91f8d9cd975f37cf7e4128f1
