Push notifications in a mobile app for Android

To use push notifications in a mobile app for Android, you must enable your app for Firebase Cloud Messaging (FCM) services. You obtain two parameters from the Firebase console and then set them in the certificate set that is associated with the Android app.

Provide the following information in the certificate set:

• FCM server key - A key that is used by the server to authenticate with the Firebase Cloud Messaging (FCM) services.
• Google Services JSON - A JSON config file for FCM-based project.

To obtain these values, log in to the Firebase console, select an existing project or create a new project, and register the Android application for Google FCM. Refer to the Google Firebase documentation for assistance with this process.
