Add Firebase to your Android project
Prerequisites
Install or update Android Studio to its latest version.
Make sure that your project meets these requirements:

Set up a physical device or use an emulator to run your app.
Emulators must use an emulator image with Google Play.
Sign into Firebase using your Google account.
