}

apply plugin: 'com.google.gms.google-services'

Like this 

Class Name : MyFirebaseInstanceIDService.java


import android.content.SharedPreferences;

import com.esteth.app.util.App;

import com.esteth.app.util.Prefs;

import com.esteth.app.util.UserModel;

import com.esteth.app.web.HttpCaller;

import com.google.firebase.iid.FirebaseInstanceId;

import com.google.firebase.iid.FirebaseInstanceIdService;

import com.google.gson.Gson;

import org.json.JSONException;

import org.json.JSONObject;





public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {




    private static
    final String TAG = "MyFirebaseIIDService";


    @Override

    public void onTokenRefresh() {


        // Get updated InstanceID token.


       String refreshedToken = FirebaseInstanceId.getInstance().getToken();


        Log.d(TAG,"REFRESHED TOKEN: " + refreshedToken);




      // Sync this fcm token in you mysql database user table


    }





    private void sendRegistrationToServer(String token) {

        // TODO: Implement this method to send token to your app server.

    }



}



put this class in your code



Class Name : MyFirebaseMessagingService.java


import android.app.NotificationManager;

import android.app.PendingIntent;

import android.content.Context;

import android.content.Intent;

import android.media.RingtoneManager;

import android.net.Uri;

import android.support.v4.app.NotificationCompat;

import android.util.Log;

importcom.google.firebase.messaging.FirebaseMessagingService;

import com.google.firebase.messaging.RemoteMessage;

import com.google.gson.JsonArray;




public class MyFirebaseMessagingService extends FirebaseMessagingService {

   

    @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());

        }



        Map<String,String> data =remoteMessage.getData();


        String type=data.get("type");             

        showNotification(title);



    }



    private void showNotification(String title) {


        Intent intent = new Intent(this, YourActivity.class);    

        intent.setAction(Intent.ACTION_MAIN);

        intent.addCategory(Intent.CATEGORY_LAUNCHER);


      
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,intent, PendingIntent.FLAG_UPDATE_CURRENT);

        Uri defaultSoundUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

       
        NotificationCompat.Builder notificationBuilder = new
        NotificationCompat.Builder(this).setSmallIcon(R.mipmap.ic_notification_icon).setContentTitle(title)

        .setWhen(System.currentTimeMillis())

        .setContentIntent(pendingIntent)       

        .setAutoCancel(true)

        .setSound(defaultSoundUri);

        

        NotificationManager notificationManager =(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(1, notificationBuilder.build());


    }




}
