Just a bug report.

I build sample code of this repository.
When start AgoraRTC video chat, the following error occurred.

I/AGORA_SDK(32650): Surface changed to width 1080 height 1808
E/RtcEngine(32470): onEvent: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.util.HashMap.put(java.lang.Object, java.lang.Object)' on a null object reference

What should I do ?

i think that error can be simply ignored for now. you can use our sdk w/o problem with that error.

@VocsyDikshit The 2.0.6 version is out-of-date, pls follow our example to migrate to the latest version.

I really Don't think migrating to a newer Version will Resolve my error as I have Already Migrated and tried once! It Shows the Same I Personally think I might have Agora sdk installation error or my Code error!

at Last my videos call app Video Switching from one Device to other Device isn't working !

you can special it by yourself.

Yes I have Tried Your Example and it Works fluently! But The Code I have Done and Yours Are Different
ex:
your- await _engine.joinChannel(config.token, config.channelId, null, 0, null);
mine; await AgoraRtcEngine.joinChannel(null, widget.channelName, null, 0);

what might be the Difference ?

@VocsyDikshit you can replace the uid and stringUid with any value.

As my Video Chat Application is online my Token is generating from Server, I am Passing null value from join Channel function
What if my Token Generation fails to generate and showing this Error? By this Reason the Videos might be not Switching to other Device? What are your thinking about it?

if you enable certificate, you must use token to join channel. you can get more info by searching on our official website.
