Android 9 Development Cookbook - Third Edition

Getting ready

Create a new project in Android Studio and call it GoogleSignIn. Use the default Phone & Tablet option and select Empty Activity when prompted for Activity Type.

Google sign-in uses the Google Services plugin, which requires a Google Services Configuration file, which is available from the Google Developer Console. To create the configuration file, you will need the following information:

• Your application package name
• Your signing certificate's SHA-1 hash code (see the Authenticating Your Client link at the end of the recipe for more information)

When you have the information, log in to this Google link and follow the wizard to enable sign-in:
