Step 8 

download your firebase google-services.json by clicking the button "google-services.json" and paste it to your android /app directory in your android project.

Step 9

Add rules to your root-level build.gradle file, to include the google-services plugin:

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Step 10

And then add the apply plugin line at the bottom of the file to enable the Gradle plugin in your module Gradle file (usually the app/build.gradle):

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.google.firebase:firebase-core:9.6.1'
    compile 'com.google.firebase:firebase-messaging:9.6.1'
    testCompile 'junit:junit:4.12'
}

Step11

click "Sync now" and wait for sync

Step12

Add a class FirebaseInstanceIDService to your project extends FirebaseMessagingService with the code show below to display notification from firebase.

package com.firebasetest.firebasepush;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFirebaseMessagingService  extends FirebaseMessagingService {
    private static final String TAG = "FCM Service";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        //super.onMessageReceived(showNotification(remoteMessage.getData().get("message")));
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        showNotification(remoteMessage.getNotification().getBody());
    }

    private void showNotification(String message) {
        Intent i = new Intent(this,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

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

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setAutoCancel(true)
                .setContentTitle("FCM Test")
                .setContentText(message)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentIntent(pendingIntent);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        manager.notify(0,builder.build());
    }
}

Step 12

Add MyFirebaseMessagingService.java as a service in your AndroidManidest.xml file.

        <service android:name=".MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>
