# Firebase Cloud Messaging
|
|
Firebase Cloud Messaging is a free service to send Notifications to your app. Firebase Cloud Messaging or **FCM** is used to send notifications to your app from either the Firebase Console or using your own server.
|
|
|
|
FCM can also carry payload or data messages along with Notification Messages. These data messages can be used as parameters to a functions which can then perform an action like check for updates from your server, make changes to shared preferences, etc to name a few possibilities.
|
|
|
|
FCM is a very powerful tool in user engagement and user retention.

# Setup Firebase Cloud Messaging in Android Studio
|
|
|
|
1. If you haven't already, [add Firebase to your Android project](https://firebase.google.com/docs/android/setup).
|
|
2. Add the following line to the build.gradle file (App level)
|
|
`implementation 'com.google.firebase:firebase-messaging:17.3.3'`
|
|
Always check if there is a new version available i.e. 17.3.+
|
|
|
|
3. Add the following code to the Android App Manifest
|
|
`<service android:name=".java.MyFirebaseMessagingService"> `
|
|
` <intent-filter> `
|
|
`<action android:name="com.google.firebase.MESSAGING_EVENT" /> `
|
|
`</intent-filter> `
|
|
`</service>`
|
|
4. Create a Java File named **MyFirebaseMessagingService** with the contents similar to [this file](https://raw.githubusercontent.com/firebase/quickstart-android/ed84b6e96933754d2d376edb761ab641fed312c1/messaging/app/src/main/java/com/google/firebase/quickstart/fcm/java/MyFirebaseMessagingService.java)
|
|
|
|
And that's it. You can now use the Firebase console to receive messages sent to the app.
