1. Verify that your Gradle files include the correct FCM and Reteno libraries
2. Download your google-services.json config file (see how here).
3. Add the above file to your root app/ folder.

4. Copy your FCM Server Key. In the Firebase console, click the gear icon next to Overview

5. Click Project Settings → Cloud Messaging → Manage Service Accounts.

6. Go to Service accounts to download FirebaseAdminSdk account's json key.

7. Follow this manual to set up eSputnik admin panel with your Firebase key.
