jwplayer for android, how to catch error

Hi, I am using jwplayer sdk for android with the latest library: compile 'com.longtailvideo.jwplayer:jwplayer-core:2.7.9+31' compile 'com.longtailvideo.jwplayer:jwplayer-common:2.7.9+31' I would like to handle when error occurs, so I implement either OnErrorListener or OnErrorListenerV2, however either playable or unplayable media url, the onError() always fires with the same error message "Invalid HTTP response code: 404: Not Found". Am I doing wrong or there is another way to catch unplayable event? Thanks.
