I want to create Android application with screen share feature

I downloaded this git repo and created app_id with my account when clicking on "Start sharing your screen" button it's showing an empty view while debugging I found token is null. Where should I get token and Audience view also showing an empty view

is there any chance you can take a look at example here?
