问题
I am working on video chat application using QuickBlox. Here is the situation, when i call from device-A to device-B and if activity on device-A just get paused or application get closed stream on device-B stop (offcourse). o when i try to call again from device-A i have to restart the application on device-B then it pick the call otherwise no call accepted on device-B and QBVideoStreamView just show the image on which it get hanged.
So what callback should be called when participant stopped the call, Actually there is a onStop() CallBack method but it gets called after so long or some time never get called.
So my question is how can get a callback if participant stopped the call or participant get away? Or any better way to recycling to get ready to receive the next call?
Actually i want to get thing smoother if call get disconnected or stopped. I can easily call back without restarting.
Edit: Crashed on recall When i recall i got this some times

回答1:
When your call gets cancelled ..before making your call again, you can call
QBVideoChatController.getInstance().finishVideoChat(videoChatConfig);
that ensures your call is finished, and the rest can begin like a normal call. If it is not absolutely necessary in your case to check for an active call
