Overview of this book

Firebase offers a wide spectrum of tools and services to help you develop high-quality apps in a short period of time. It also allows you to build web and mobile apps quickly without managing the infrastructure.Mastering Firebase for Android Development takes you through the complete toolchain of Firebase,including the latest tools announced in Google IO 2018 such as Firebase ML-Kit, FireStore, and Firebase Predictions. The book begins by teaching you to configure your development environment with Firebase and set up a different structure for a Firebase real-time database. As you make your way through the chapters, you’ll establish the authentication feature in Android and explore email and phone authentication for managing the on-boarding of users. You’ll be taken through topics on Firebase crash reporting, Firebase functions, Firebase Cloud, Firebase Hosting, and Cloud Messaging for push notifications and explore other key areas in depth. In the concluding chapters, you will learn to use Firebase Test Lab to test your application before using Firebase Performance Monitoring to trace performance setbacks. By the end of the book, you will be well equipped with the Firebase ecosystem, which will help you find solutions to your common application development challenges.

Trigger functions 


Triggers are the mechanisms that allow a Firebase function to detect a change in the state in Firebase tools. For instance, when the Realtime Database adds a new entry, it triggers a function. Essentially, Triggers are event suppliers. In this section, we will explore the following triggers:

  • Cloud Firestore Triggers
  • Realtime Database Triggers
  • Firebase Authentication Triggers
  • Google Analytics for Firebase Triggers
  • Crashlytics Triggers
  • Cloud Storage Triggers
  • Cloud Pub/Sub Triggers
  • HTTP Triggers

Let's understand each tool in detail. 

Cloud Firestore Triggers

Cloud Firestore is a recent release of the Firebase toolchain. Google labels it as the flexible, scalable NoSQL. To work with Function triggers for Firestore, you don't need to write extra code on the client side. Changes to Firestore can be achieved via DeltaDocumentSnapshot, which is an interface representing Cloud Firestore documents. The Cloud Firestore Function typically does the following actions:

  • It anticipates changes to...
