That most likely happened because the player was accessed from different threads simultaneously.

Please note that all player methods must be called from the same thread. This must be the thread you created the player on (or the main thread if that thread doesn't have a Looper). We also recently added an option for #4278 to specify your own Looper to use for player access.

Closing for now as the question is answered and the discussion in #4463 is used to track changes regarding this problem.
