1. Get Started
Add a new project or import an existing project to Firebase console.
If you choose to create a new project, you need to set the project name and country. For example, I will call my project Abc Mobile Security.
Then select “Add Firebase to your Android app”.
Set a package name for your app. I only set my package name and omit the SHA-1 because I don’t use Firebase for my app’s authentication.
Click the ADD APP button here to download google-services.json. This is an important file and you will need to put it into your app.
2. Add Google-Services.Json To Your App Folder
Replace the google-services.json in your app folder. The Google services plugin for Gradle will load the google-services.json file you just downloaded.
