I understood what you are saying, but I can’t find any appropriate way to full fill my needs. According to you, if one needs to make custom ui, he needs to use set custom ui flag to true and build up the ui on its own. But according to the example 2 provided with SDK, it has a class MyMeetingActivity which extends MeetingActivity and has build up completely customised ui using this class, which is confusing me on my implementation. According to this thread, what i want can be achieved by extending Meeting Activity. But I am unable to find any appropriate documentation on this. It would be very helpful if you could provide any proper documentation or step by step guide on implementation of MeetingActivity.
