    Firebase: Save, Delete and Retrieve data from firebase database in Android Studio

    In Firebase Realtime Database we can store and sync data with our NoSQL cloud database. Data is synced across all clients in realtime, and remains available when your app goes offline.

    The Firebase Realtime Database is a cloud-hosted database. Data is stored as JSON and synchronized in realtime to every connected client. When you build cross-platform apps with our iOS, Android, and JavaScript SDKs, all of your clients share one Realtime Database instance and automatically receive updates with the newest data.

    Android Setup

    Here is the one example how to store on firebase and retrieve data on your android device.

    First step Create firebase project  from https://console.firebase.google.com.

    Add the dependency for Firebase Realtime Database to your app-level build.gradle file:

    2. Get data from your form
    3. Add and push data on database
    4. Update on your view using creating anonymous inner class ChildEventListener.
