MCU3.1.1 crash again!

[Somnus_Chen]

Hi,

   I used android app to create a conference chat.But my network is 3G.

  Theoretically, I press a join button,program will excute "create room">"get token">"join room">"publish localStream" and so on. But  the 3G signal is not stable or strong, the whole proccess takes a long time.I have no patiece, the I press the exit button immediately. Finally,the MCU crash.

ConferenceClient ​void

join (string token, function onSuccess, function onFailure)

 If I got a valid token to join in an empty(deleted) room.It will cause this situation.

Thanks for reporting this, we will try to reproduce that.

Yes, this is the product defect for this corner case. Try the attached patch file to replace Release-v3.1.1/nuve/rpc/rpcPublic.js, it should fix your issue.

[Lei_Z_Intel1 · Accepted solution]

Attach patch file.

[Somnus_Chen]

Thanks a lot.
