sending push notification with firebase - FATAL EX

First attempts at getting firebase push notifications to work isn't going so well. I have followed the tutorial listed here to set it up, but whenever I try and send a notification, the app "closes unexpecedly", and the logical throws the following crash information:

You need to add the empty constructor in the class MyFirebaseMessagingService

public MyFirebaseMessagingService() {
    super("MyFirebaseMessagingService");
}

For explanation, you can see the details here

I haven't tested it, but I suspect that your services cannot be inner classes of MainActivity. It would be safer, and may be required, to declare them as non-nested classes, as is done in the sample project:

MyFirebaseInstanceIDService

MyFirebaseMessagingService

It's also possible that the services can be nested classes of MainActivity if you declare them as static nested classes:

public static class MyFirebaseMessagingService...

check if you have different version with dependency implementation

implementation 'com.google.android.gms:play-services-gcm:+'
implementation 'com.google.firebase:firebase-core:+'
implementation 'com.google.firebase:firebase-messaging:+'
