Build Status

The source code in this repo accompanies my article Creating Clean Architecture Multi-Project MVP App.

Here you will find a multi-project single Activity TODO app using Conductor implementing MVP pattern (each Controller is a View).

Main Libraries

  • Conductor
  • Room (with fully reactive data types)
  • RxJava 2 and RxAndroid
  • Dagger 2 with custom scopes
  • ButterKnife for view binding

Multi-Project setup

The app is configured as multi-project Gradle setup which improves build and testing speed in addition to providing clear isolation between the components of the app:

  • domain module contains business logic/use-cases/repository interfaces as well as Model
  • data module contains implementation of the domain layer abstractions
  • presentation module contains Views and Presenters as well as Dependency Injection setup that glues all layers together

Relationship between modules

This setup enables you to swap your backend implementation (for instance, migrate to Firebase or Realm) simply by replacing your data layer module and modifying a dependency in the presentation module. If the data layer changes, domain layer is not affected.

Code Quality

This project aims to maintain high test coverage for all modules.

Unit test code coverage is at 96% (Views are excluded from unit tests since they are rather passive).

Main libraries used for testing are:

  • JUnit
  • Mockito-kotlin
  • Hamcrest
  • Jacoco
