): Unit

Implement this to handle transfer seamlessly.

Setting the listener will defer stopping the previous route, from which you may get the media status to resume media seamlessly on the new route. When transfer is prepared call TransferNotifier#notifyPrepareFinished() to stop media being played on the previous route and release resources.

Callback#onRouteUnselected(MediaRouter, RouteInfo, int) and Callback#onRouteSelected(MediaRouter, RouteInfo, int) are called just after this is called and the selected route is changed. You may begin transferring media when Callback#onRouteSelected(MediaRouter, RouteInfo, int) is called.

fromRoute MediaRouter.RouteInfo: The route that is about to be unselected.
toRoute MediaRouter.RouteInfo: The route that is about to be selected.
transferNotifier MediaRouter.TransferNotifier: the object used to notify finish of preparation.
