Question

 though i have check event!=null i am getting null pointer exception in 
 event.getJoinedUsers().length in onGetLiveRoomInfoDone method

Answer 1

Hi Bhavesh,

Greetings!!!!!!!!

As you are implemneting the CallBack, you need to apply null check as well on  event.getJoinedUsers() as well before calculating its length.

Let me knwo if more queries are concern.
