android-clean-architecture

A clean architecture example. Using Kotlin Flow, Retrofit and Dagger Hilt, etc.

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 you/your team preferences. This app have little bug. If you go from FragmentA to FragmentB, then go back, the fragmentA re render again. I Know how to fix it but I dont have time to do it. Search for "retain fragment jetpack navigation", use the newest solution
