Notes

• Jetifier is enabled inside gradle.properties. Even though it's not necessary for the current dependencies, it was left enabled so anyone can start using the template without worrying when to turn it on. We do recommend you to check Can I drop Jetifier? when expanding the template.
• Android Template contains .github/workflows for lint check and unit testing. You can easily take this project worflow and repurpose it with a few path changes, you can also find a commented example in test.yml for Instrumentation Testing and CodeCoverage that we advice to keep a clean project, you will however need to replace the secret keys with your own.
