Cast companion library change video without restarting activity?

I have built an application that uses Cast Companion Library (CCL) to remotely play video to cast comparable devices. Every thing is working find but I need to be able to change video files and not kill and restart the activity and fragment.

I have implemented my own custom version of the VideoCastControllerActivity that implements the same interface but I am re-using the VideoCastControllerFragment that CCL comes with. One problem is that the VideoCastControllerFragment does not really give specific notice when the end of a video file is reached. It somewhat does by calling closeActivity() from the IVideoCastController interface so I tried to use that event to know when to load the next video file. But loading the next video file by calling 

getCastManager().loadMedia( mSelectedMedia, autoPlay, position );

but doing that results in another call to close activity and a loop until the end of the playlist is reached without playing any video.

Is there another way to go about this without re-writing my own VideoCastControllerFragment?

To answer your first question (or observation), you can listen to various callback events directly in your implementation of VideoCastControllerActivity; you have access to the VideoCastManager so you know when your media status goes to IDLE with the reason FINISHED. Outside of that, you seem to be trying to implement some sort of playlist functionality in your sender while the right place for that is on the receiver (i.e. you need to write a custom receiver); if your playlist knowledge/logic lives on your phone, then the whole thing becomes dependent on your phone so if it goes to sleep, you chromecast doesn't know what to do. In addition, if a second device connects to the same cast device, it cannot correctly reflect the playlist, etc. So a phone device can let user form a playlist and then it has to send the information about that playlist to your custom receiver and your custom receiver should handle playing them in queue and your sender(s) should be able to send custom messages to move to the next/prev, etc and your receiver should do the right thing accordingly. We have a very rudimentary sample on our GitHub repo that shows how you can do video playlist on the receiver.
