Android - VideoChat ( Powered by Jitsi )

I am looking for an android app developer to finish up a project that was worked on by another freelancer, but because of unforeseen circumstances, he/she couldnt finish it. Its a video chat app, made in visual studio, for android devices. It is powered by jitsi, that is currently self-hosted on my own server.

You must be familiar with jitsi or at least can learn it quickly in a short amount of time.

I need you to:

1. Complete the android video chat app. (Will discuss further)

2. Customize the chat so that it has my brand and not jitsi.

3. The app must run in kiosk mode in order to prevent users from exiting app.

4. Add screensaver when app is idle.

5. Fix exit chat ( when a user ends their chat on their device, the other party is still showing like theyre in a chat session. I need it to be where if one user exits the chat, the other party session will exit as well.

6. Minor customization: changing wallpaper, contact list design, etc

**you must do this with android studio and provide the source codes when done/requested. No exceptions.

**your bid is the final project cost, so bid accordingly. Thanks

Looking forward to working with you.
