Setting up Google Maps

If you intend to send notifications that use the map capabilities, you must enable the Google Maps API and configure your app with an API key. This guide walks you through enabling Google Maps SDK in the Google Cloud Console and adding the required configuration to your Android project.

You will be directed to the project's Welcome page. In the Quick Access section, click APIs & Services:

From the API library, locate and select Maps SDK for Android:
