Steps to make on server side:

1. Go to firbase console.

2. Now add a project.

3. Select platform in which you want to add firebase.

4.Now add package name of your project in window and you can add other options over there too.

5.After this "google-services.json" will be generated. Download this

6. Switch to the Project view in Android Studio to see your project root directory.

7. Move the google-services.json file you have just downloaded into your Android app module root directory.

Now in Android Application:

Project-level build.gradle (<project>/build.gradle):

buildscript
	{	  
        dependencies
	{
	classpath
	'com.google.gms:google-services:3.1.0'
	  }}

	
App-level build.gradle (<project>/<app-module>/build.gradle):
Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'
//add firebase sdk in dependency:
compile 'com.google.firebase:firebase-messaging:9.4.0'

Create two classes name whatever you want:

1.MyFireBaseInstanceIdService

2.MyFireBaseMessagingService

//--------------------------------------------------MyFirebaseInstanceIdService--------------------------------------------//

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private SessionManager sm;
    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        sm=new SessionManager(getApplication());
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.e("TAG", "Refreshed token: " + refreshedToken);
        //saving registration token in shared prefernces
        sm.setSaveRegisterationToken(refreshedToken);
       

    }
}

//--------------------------------------------------------//

//--------------------------------------------------MyFirebaseMessagingService--------------------------------------------//

public class MyFirebaseMessagingService extends FirebaseMessagingService {

   
    public static final String TAG = "FIREBASE";
    
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(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> params = remoteMessage.getData();
            JSONObject object = new JSONObject(params);
            Log.e("JSON_OBJECT", object.toString());
            String body=object.optString("body");
            String title=object.optString("title");
            String notificationType=object.optString("notificationType");
            sendnotification(body,title,notificationType);
        }

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

        //sendnotification(mesg);
    }

public void sendnotification(String mess,String title,String noti_type) {
    // TODO Auto-generated method stub
    NotificationManager mNotificationManager = (NotificationManager)getApplication()
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Bitmap largeicon= BitmapFactory.decodeResource(getResources(), R.drawable.applogo);
    PendingIntent pendingIntent = null;
    Intent intent=null;
   
        intent=new Intent(getApplication(),SplashActivity.class);
        
   pendingIntent = PendingIntent.getActivity(getApplication(),0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
    mBuilder.setLargeIcon(largeicon);
    mBuilder.setSmallIcon(R.drawable.applogo);
    mBuilder.setContentTitle(title);
    mBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
    mBuilder.setContentIntent(pendingIntent);
    mBuilder.setAutoCancel(true);
    mBuilder.setStyle(new NotificationCompat.BigTextStyle().bigText(mess));
    mBuilder.setContentText(mess);

    mNotificationManager.notify(NOTIFICATION_ID,mBuilder.build());
}
