Pusher relies on Firebase Cloud Messaging (FCM) to deliver push notifications to Android application users on your behalf. When we deliver push notifications, we use your FCM credentials. This page guides you through the process of getting an FCM Server Key and how to provide it to Pusher.
The first step is to go your Firebase console.
You'll now need to either create a new app, or use an existing one. If you're using one you already own, then you can jump to Get Your FCM Server Key.
Once the app is registered, you should click the download google-services.json .
You need to move this file to your Android app project directory. After doing this, your application will be ready to use FCM.
Now go to the Pusher Beams instance in the dashboard, and use this FCM Server Key to configure your Android integration.integrate our Android SDK into your project.
