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.

Setting up a development environment 

To get started, we need to integrate the Firebase SDK to the project, and it is a one-time integration. Later, we can choose any of the Firebase tools that we want to work with and add the appropriate gradle dependency. 


To develop Firebase applications, you can surely use your development environment; the essential requirements are as follows:

  1. Your favorite operating system (Windows, macOS, or Linux)
  2. Determine whether you have the latest JRE installed on your operating system
  3. Install the latest version of JDK or Open JDK
  4. Install the newest version of Android Studio (at the time of writing, the most recent stable version is 2.3.3 and 3.0 is still in beta, or any newer version should also be excellent)
  5.  Android SDK with one complete API will be very significant


Before we continue to create our first Firebase Realtime Database Android application, ensure that you have one complete version of Android API installed, and you have the latest version of Android Studio.

Configuring Firebase in Android projects

There are two ways that you can connect Firebase to your Android project, from the Firebase console creating the new project and adding the dependencies and Google config file. The other way is just to add Firebase support to an Android project directly from Android Studio:

  1. The usual way of connecting Firebase is to visit the Firebase console at
  2. Create a new project using the Add Project button, and if you already have an existing project, you are free to choose it
  3. In the overview section of the console, you can choose to add an Android application by clicking on the relevant button and add the necessary information to the fields
  4. Download the google-services.json file, add it to your project's app folder root, and the classpath gradle dependencies in the project's gradle file
  5. To reduce the effort, we can make Android Studio do all this for us by choosing the Tools Firebase menu option and clicking on the Firebase tools that you want to integrate from the list
  6. After you chose the Firebase tool, tap on Save and retrieve data
  7. In the next window panel, you will see options such as Launch in the browserConnect your app to Firebase, and so on, click on theConnect your app to Firebasebutton and select your project or you can create the new project in the Connect to Firebase window
  8. Go back to the Firebase panel and click on theAdd the Realtime Database to your applicationbutton

Since we have connected to Firebase, it is as simple as it sounds, all we have to do is select the Add the Realtime Database to your application button in the Firebase assistance window, you will see a dialog for requesting your authorization to change the gradle file with a few dependencies. Tap on Accept Changes, now we are all set to explore Realtime Database abilities.
