RuntimeException: cannot perform action, you are not holding a lock

[RameshJangama]

I have ported this VideoPlayerManager in my app. Whenever I refresh layout to get new videos from API, next video is not automatically playing. While debuging I found below exception. Has any one seen this problem? Any pointer or suggestions to fix this?
