This is a simple demo that shows how to use Firebase realtime database and displaying the data inside a ListView.
You can add, edit, or delete items, and the database database gets updated and the changes are instantly reflected in the UI.
There are two modules:

• app: This module contains the Java implementation.
• kotlinapp: This module contains the Kotlin implementation.

This repo is related to the following post.

Important Note

The project DOES NOT contain the google-services.json file, you must create your own Firebase project and use your own google-services.json file in order to be able to use this project. You can check this post here where I thoroughly cover how you can integrate Firebase in your project, or feel free to check the official documentation here.
