Answer 1

You can do by this way,When user enter the data into the firebasedatabase.
On Response Successfully,You can set the value against that currently user in firebasedatabase user node. Then using addValueListener of firebase database to check that value which you set if exist then create a push notification like this

    NotificationManager notif=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notify=new Notification.Builder(getApplicationContext())
.setContentTitle(tittle)
.setContentText(body)
                   .setContentTitle(subject)
.setSmallIcon(R.drawable.abc)
.build();

notify.flags |= Notification.FLAG_AUTO_CANCEL;
notif.notify(0, notify);

After this set value to null after push notification.
I hope its helpful for you!
