How to receive a notification to android user, when ever firebase database is updated?

I have an android application connected with firebase. When ever a new child is added to the database I need the user to be notified via a notification message. Moreover, in my application the user selects a code (eg: 71000,00100,90288) and this code is stored in shared preferences. I need the user to be notified when ever a child is added or modified, only as the code selected by the user. Any help, highly appreciated.Thank you so much in advance.

On firebase, we got callbacks to provide realtime database functionalities.

Ways of doing so:

  • Register a onChildAdded listener to the firebase node URL and it get triggered whenever a child is added and you can run a service that could cause notification payload which run on client side.
  • use Firebase cloud functions which run on service side.

if your server side is firebase ,to send notification when child added , you need to create a firebase cloud function which will do that so this what you will do :

  • create firebase cloud function
  • send data with notification ( using payload )
  • after receiving data in your service ( Messaging listner )check if the data ( number ) is equal to some of saved numbers in shared preferences
