I followed the tutorial from this link http://blog.nkdroidsolutions.com/android-push-notification-example-using-firebase/ but I am not not receiving any notification on my device.

I checked and tried these links too, but could not find a solution
android - Firebase Notification Push Notification not working
Push Notification not Received in android

In my firebase console, the notification sent is 0. Here is my androidManifest File

 <?xml version="1.0" encoding="utf-8"?>

Firebase Messaging Service file

package FirebaseConnection;

import android.util.Log;

import com.google.firebase.messaging.RemoteMessage;
public class FirebaseMessagingService extends 
com.google.firebase.messaging.FirebaseMessagingService 
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage)

 Log.d(TAG, "From: " + remoteMessage.getFrom());

 // Check if message contains a data payload.
 if (remoteMessage.getData().size() > 0) 
 Log.d(TAG, "Message data payload: " + remoteMessage.getData());
 

 // Check if message contains a notification payload.
 if (remoteMessage.getNotification() != null) 
 Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
 

And the Firebase ID Service

package FirebaseConnection;

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class FirebaseIDService extends FirebaseInstanceIdService 
private static final String TAG = "FirebaseIDService";

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

 // TODO: Implement this method to send any registration to your app's servers.
 sendRegistrationToServer(refreshedToken);


/**
 * Persist token to third-party servers.
 *
 * Modify this method to associate the user's FCM InstanceID token with any server-side account
 * maintained by your application.
 *
 * @param token The new token.
 */
private void sendRegistrationToServer(String token) 
 // Add custom implementation, as needed.

Any help would be appreciated.

Regards

The problem is the name of your class!

Manifest: MyFirebaseMessagingService

Service class: FirebaseMessagingService

the name of the two must be the same
