If you want to use the app with your own server and want push notification to work you have to set them up:

Register at https://firebase.google.com/, set up the project if you have not done so already.
Download your own config file google-services.json and place it to the app/ folder of your copy of Tindroid project. The config file contains keys specific to your Firebase/FCM registration.
Copy Google-provided server key to tinode.conf, see details here.
Recompile the app. If you add google-services.json incorrectly the app will compile but will later crash with non-obvious exceptions.

The app is currently available in the following languages:
