You can also filter the sorted result to a specific number of results or a range of keys or values. Data is stored as JSON and synchronized in realtime to every connected client. The REST API accepts several query parameters when reading data from our Firebase database. You can make Firebase Realtime Database changes via the DataSnapshot or via the Admin SDK. It builds on the successes of the Realtime Database with a new, more intuitive data model. Firebase Realtime Database is the backend service which is provided by Google for handling backend tasks for your Android apps, IOS apps as well as your websites. When you build cross-platform apps with our Android, Apple platforms, and JavaScript SDKs, all of your clients share one Realtime Database instance and automatically receive updates with the newest data. By enabling persistence, any data that the Firebase Realtime Database client would sync while online persists to disk and is available offline, even when the user or operating system restarts the app. To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio.Note that select Java as the programming language.. Step 2: Connect your app to Firebase. Follow the database creation workflow. Firebase allows you to do ad-hoc queries on your data using an arbitrary child key.
