An Android project template based on Clean Architecture using architecture components library (Live data, View model and Room), RxJava2, Dagger2 and Retrofit2.

Android Clean Architecture

This project is based on Clean Architecture by Robert Cecil Martin aka Uncle Bob.
It uses android architecture components (Live data, View model and Room) with RxJava2, Dagger2 and Retrofit2.

Key benefits

1. Create extensible and reusable modules to use across multiple apps.
2. A system that is intrisically testable, independent of frameworks, database and UI
3. When some frameworks or libraries become obsolete easily replace them with new ones.

Using this template

There are three main packages.

base : all your base classes go in this package
features : all your features related code go in this package
app : all your high level classes that combine multiple features go in here.

base and feature packages are divided into four standard packages (data, presentation, usecases and entities).

Understanding Clean Architecture

Key principle: Nothing in an inner circle can know anything at all about something in an outer circle

To understand and adapt clean architecture on android apps, take a look at the following great articles:
