Adding more detail in documentation

My humble question is can we call RtcEngine.create(this, app_Id, mHandler); mRtcEngine.setChannelProfile(io.agora.rtc.Constants.CHANNEL_PROFILE_LIVE_BROADCASTING); multiple times and what are the effects on doing so?

agora sdk is globally single instance so you will get the same instance if you call it multiple times.
