In my programmatically, i have calls startPlayer() in onStart() callback and pausePlayer() in onStop()
andExoPlayerView.startPlayer() andExoPlayerView.pausePlayer()
in addition, i calls setSource() inside BindingAdapter file
view.setSource(url)
crash occurs at line com.potyvideo.library.AndExoPlayerView.onPlayerError (AndExoPlayerView.java:1)

This looks like a bug in com.potyvideo.library.AndExoPlayerView. It is unconditionally calling ExoPlaybackException#getSourceException without first checking if ExoPlaybackException#type == TYPE_SOURCE:

From the ExoPlaybackException#getSourceException javadoc:

Throws: IllegalStateException - If type is not TYPE_SOURCE.

I suggest you report this to the maintainers of AndExoPlayerView.
