title: The zoom sdk for video conferencing integrated properly but the top layout which contains camera, audio button is missing
body: <p>I have downloaded the sample app from here “<a href="https://github.com/zoom/zoom-sdk-android" rel="nofollow noreferrer">https://github.com/zoom/zoom-sdk-android</a>” and and I am referring “example2: An Android app that shows how to join meeting without any login credentials.” its working fine but when I am trying to integrate zoom sdk in another dummy app everything works fine except the layout in the MyMeetingActivity (at the top) which contains Audio,Camera,Share,Participants,More and Leave Buttons is not visible though I am using the exactly same files(MainActivity.java,MyMeetingActivity) from the sample project downloaded from the above git link.</p>
