Android App Composable Template

This is a template to build an Android app applying good practices and using a clean architecture, you will see that the code is super decoupled with external frameworks and even with the same Android framework, this will help you to model your domain purely in Kotlin without generating external dependencies.

Application architecture

In the following images you will see how the app is built and what its levels of abstraction are.
