Intro

Architecture means the overall design of the project. It’s the organization of the code into classes or files or components or modules. And it’s how all these groups of code relate to each other. The architecture defines where the application performs its core functionality and how that functionality interacts with things like the database and the user interface.

Clean architecture refers to organizing the project so that it’s easy to understand and easy to change as the project grows. This doesn’t happen by chance. It takes intentional planning.

Notes

I created this app just for example how to implement clean architecture on android. It really biased to my preference and experience. Also, clean architecture is not mandatory to do. If you feel that you/your team are taking so much benefit by implementing this design pattern, then go for it. Otherwise, don't use it or just modify to your/your team preferences.

Main Picture

There are 3 layer in this app.

Presentation Layer	Domain Layer	Data Layer
your ui/view	entity	data source, dto
your viewmodel	usecase	repository implementation
probably your extension	repository interface	your library config(retrofit/room)
etc...	etc..	etc...

App Level Example

Presentation Layer	Something in Between	Domain Layer	Data Layer	Outer data layer
LoginActivity & LoginViewModel	<- LoginUseCase ->	<- LoginRepository (interface) ->	<- LoginRepositoryImplementation	DataSource
