How does firebase cloud messaging ( fcm ) work?


Asked by Lyra Nelson on Dec 03, 2021 Mini Program Cloud Development Study Guide



How does it work? Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably send messages at no cost. This resource may not be available in your region. Using FCM, you can notify a client app that new email or other data is available to sync.
Consequently,
Firebase Cloud Messaging (FCM) is the newest version of Google Cloud Messaging (GCM). FCM helps to send notification and messages to devices. FCM have almost similar features as GCM. A brief note on the features of FCM is listed below: Notification payload: 4KB, Message payload: 2KB.
Similarly, Add the Xamarin Firebase Messaging package. To receive messages from FCM, the Xamarin Firebase - Messaging NuGet package must be added to the app project. Without this package, an Android application cannot receive messages from FCM servers.
Subsequently,
Firebase serves as a module between your server and the devices that will be receiving the push notifications that you create. Your server informs Firebase that a notification has to be sent. Then Firebase does the work behind the scenes to get the notification published. How to integrate FCM into Android Project?
Thereof,
Set up a Firebase Cloud Messaging client app on Android. To write your Firebase Cloud Messaging Android client app, use the FirebaseMessaging API and Android Studio 1.4 or higher with Gradle. The instructions in this page assume that you have completed the steps for adding Firebase to your Android project.
