App deployment setup
Codemagic
Codemagic is not a required service for this project. You're welcome to use other automated CI/CD services for your apps, if desired.
Codemagic is an automated CI/CD service that streamlines deployments to the Google Play Store and App Store Connect. You can configure your CI/CD pipeline up front and trigger deployments automatically with each subsequent code change.
To use this service, login or create a Codemagic account and follow the getting started guide guide to set up a codemagic.yaml build configuration file. Be sure to populate all 'TODO' fields in your codemagic.yaml file.
For this project, specifically, be sure to create an App Store API Key and add this to your Codemagic account. In addition, generate a keytore for signing your release builds.
A service account is required when publishing to Google Play. The service account JSON key file must be added to Codemagic to authenticate with these services. To set up a service account for authentication with Google Play and Firebase, use the instructions at Google services authetication.
