Thanks for using Zoom SDK. You can define your own MeetingActivity, for example, MyMeetingActivity and inherit the SDK’s MeetingActivity like this:
public class MyMeetingActivity extends MeetingActivity
and then set the following in your config.xml(https://github.com/zoom/zoom-sdk-android/blob/master/mobilertc-android-studio/example2/src/main/res/values/config.xml#L4):
<string name="zm_config_conf_activity">MyMeetingActivity</string>
Then you can implement your own business logic or constraints (like blocking the screen short or screent recording) in MyMeetingActivity. You may refer to the implementation of example2 in our demo app:https://github.com/zoom/zoom-sdk-android/tree/master/mobilertc-android-studio/example2
Hope this helps. Thanks!
