In this course, you’ll learn how to use Firebase. Firebase is a cloud backend, and one of the leading choices for Backend as a Service. It enables you to quickly get synchronized data up and running for multi-user apps. This is important because nearly every mobile app these days requires authentication and real-time data updates.

We’ll begin by showing you how easy it is to read and write almost any data to Firebase. After that, we’ll teach you how to allow users to login and have data associated with them. We’ll then cover how to write queries and filters for your data. You’ll discover how to take advantage of Firebase's offline capabilities, and master efficient database design for lightning-fast data retrieval. Lastly, you’ll learn how to use Firebase’s Security and Rules language to secure and add permissions to your data.

By the end of this course you will have an Android application that can store and share data between different users in real time as well as authenticate and authorize those users.

Why Take This Course?
If you are an Android developer and your app needs any of the following features:

- Online data storage
- Real-time synchronization between many users
- Authentication for Email/Password as well as OAuth providers
