When An App Is In Background, Onmessagereceived Method Is Not Firing

Actually i need to show badge in app icon but i don't know how to get badge and why onMessageReceived not call when app is in background or app is not running. public class Custom_

Solution 1:

There are two types of FCM

notification Messages: Sending a payload with this message type triggers onMessageReceived() only when your app is in foreground.

data Messages: Sending a payload with only this specific message type triggers onMessageReceived() regardless if your app is in foreground/background.

Reference: https://firebase.google.com/docs/cloud-messaging/android/receive#handling_messages

Solution 2:

Add service to AndroidManifest.xml. Also make sure token is not expired.

<serviceandroid:name=".FirebaseMessagingService"><intent-filter><actionandroid:name="com.google.firebase.MESSAGING_EVENT"/></intent-filter></service>

Refresh Token if it is expired.

@OverridepublicvoidonTokenRefresh() {
    // Get updated InstanceID token.String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // If you want to send messages to this application instance or// manage this apps subscriptions on the server side, send the// Instance ID token to your app server.sendRegistrationToServer(refreshedToken);
}
