Is it a bug about publish limit

Hi, 

     I found a problem about publishLimit by using Android SDK communicating with MCU conference server, not sure it's a bug or not. The situation like this:

1,  set publishLimit = 1 in Test room which was just created.

2, user A join Test room, publish his local stream successfully.

3, user B join Test room, publish local stream. Then was notified publish success. after few minutes, onIceConnectionChange()  change status to FAILED, but callback is null in this ActionCallback publishCallback = (ActionCallback)this.pendingCallbacks.get(stream.getMediaStream().label()) ,onStreamActionFailed() of conferenceClient.class.

so the

if(publishCallback != null) {
    publishCallback.onFailure(e);
} 

never get in. The caller never now published failed actually. I check the log file on MCU conference server, the woogen-portal.stdout show this:  INFO:SocketIOServer - emitted connection_failed, reason: controller.publish failed, reason: Too many publishers.

4, user B logcat of Android Studio :

Version 3.3.1 and 3.4 are the same behavior.

I found the solution on Version 3.4, by using the 

onStreamError()

 

Please close this topic.

Thanks Leo,

prior to v3.4, Android SDK won't have any notification when the peerconnection fails after callback for publish/subscribe has already been triggered once.

in v3.4, onStreamError will be triggered as a notification for application, upon the MCU server detects any failure on the peerconnection after publish/subscribe. More info please refer to doc.
