android - Got New Notification when a new child added in Realtime database or changed some database

Question

I am using Android 4.1.1 version I got a notification when I start the android app if anyone Child exits I want only notification when a New Child is added to my database or the existed child changes some info.

This is the Code for notification

private void notification() {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            NotificationChannel channel = new NotificationChannel("n", "n", NotificationManager.IMPORTANCE_DEFAULT);
            NotificationManager manager = getSystemService(NotificationManager.class);
            manager.createNotificationChannel(channel);

        }

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "n")
                .setContentText("My Channel")
                .setSmallIcon(R.drawable.icon_service)
                .setAutoCancel(true)
                .setContentText("New Service is Added");
        NotificationManagerCompat managerCompat = NotificationManagerCompat.from(this);
        managerCompat.notify(1064, builder.build());


    }

here I called this notification function in on create method:

databaseRef.addChildEventListener(new ChildEventListener() {
    @Override
    public void onChildAdded(@NonNull DataSnapshot snapshot, @Nullable String previousChildName) {
            notification();
    }

    @Override
    public void onChildChanged(@NonNull DataSnapshot snapshot, @Nullable String previousChildName) {
        notification();
    }

    @Override
    public void onChildRemoved(@NonNull DataSnapshot snapshot) {
    }

    @Override
    public void onChildMoved(@NonNull DataSnapshot snapshot, @Nullable String previousChildName) {
    }

    @Override
    public void onCancelled(@NonNull DatabaseError error) {
    }
}); 

Thank you in advanced
