6 years ago Awesome, thanks! The 'BAD' url above should generate a 401 or 403 error, which should be enough to reproduce the problem (or, you can use any SoundCloud URL without specifying a valid client_id).
I guess if the streaming URL does result in a 4xx error, it would be good to catch that and make sure the next track starts playback without any issues. Other than that, the error handling seems good - I'm not too familiar with Objective-C but it seems like the 'bad track' gets removed from the playlist after the user first tries to stream it?

6 years ago @codinronan I've had the chance to play with this a bit in an application now, and it seems the player automatically tries to 'skip' past the offending track and play the next one. Sometimes this works really well, and the next / previous track starts playing, but other times it doesn't work so well - the new track can be muted, or you can't skip back past a certain point in the playlist.
Would it be possible to throw some kind of status error up to the application, and let it decide how to handle this? Or might this interrupt the continuous lockscreen / background playback?
Even if it's better to handle the error in this plugin, it would be really useful to get an error status thrown up to the application somehow, so that appropriate action can be taken (greying out the track in the UI / displaying an error message to the user, for example)

5 years ago I think the best way to handle this is by catching RmxAudioStatusMessage.RMXSTATUS_ERROR status messages with code RmxAudioErrorType.RMXERR_DECODE when adding tracks to the playlist
Expected Behaviour
When the HTTP request to stream a playlist track is rejected (i.e. the response is an HTTP 4xx client error), the playlist should handle this gracefully, by continuing on to the next track on the playlist (or the previous track, if the user was skipping backwards through the playlist)
Actual Behaviour
The lockscreen UI indicates that the next track is playing, but no music can be heard. It is possible to work around the issue by skipping back and forwards through the tracks, which can cause the music to start playing again.
Reproduce Scenario (including but not limited to)
iOS with Ionic, streaming tracks from SoundCloud using stream URLs
Steps to Reproduce
Create a playlist with at least two valid streaming tracks. In between the two valid tracks, have another streaming track with URL
https://api.soundcloud.com/tracks/274436003/stream?client_id=abcdefg- using an invalid SoundCloud key as shown here will cause an HTTP 401 error, which should be enough to reproduce the error.Play the first track, and skip forward, or wait for the first track to end. The invalid track will be skipped over, and the lockscreen controls will display track information and playback information suggesting the next valid track is playing, when in fact no music is being played by the device.
Platform and Version
iOS 11.4
