About this course

In this course, you’ll learn how to use Firebase. Firebase is app development platform that provides developers a variety of tools and a scalable infrastructure to build high quality apps.

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, have data associated with them and send them notifications. You’ll learn how to use Firebase’s Security and Rules language to secure and add permissions to your data.

Firebase Remote Config gives you the ability to tune and customize your app without having to publish a new version. Finally we’ll give you a brief overview of Firebase Analytics so you can collect data from the start.

Got extra time this weekend? As a bonus, you will write your own Cloud Function for Firebase that makes chat more fun by adding emojis to FriendlyChat conversations. Cloud Functions for Firebase integrates the Firebase platform by letting you write code that responds to events and invokes functionality exposed by other Firebase features.

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.
