PickMe's Clean Architecture for Android Applications
Original post Clean Architecture for Android Applications
Article Summary
Chamod Lakmal from PickMe breaks down Clean Architecture for Android with a practical folder structure that actually makes sense. If your codebase feels like spaghetti, this is your roadmap out.
This article explains how to implement Uncle Bob's Clean Architecture pattern in Android apps, focusing on separation of concerns across three distinct layers. Lakmal provides concrete code examples and a detailed folder structure that teams can adopt immediately.
Key Takeaways
- Three core layers: Presentation (UI), Domain (business logic), Data (repositories)
- Complete folder structure includes ViewModels, Use Cases, and Repository patterns
- Code examples show ViewModel, UseCase, and Repository implementation in Kotlin
- Independent layers enable isolated unit testing for each component
- Initial effort pays off by reducing technical debt long term
Clean Architecture transforms Android apps into maintainable, testable systems by strictly separating UI, business logic, and data layers with clear interfaces between them.

What This Article Covers
As Android codebases grow, they become harder to manage and maintain. Multiple development teams need a structured way to handle dependencies and keep technical debt under control.
Chamod Lakmal at PickMe applied Uncle Bob's Clean Architecture pattern with three layers: Presentation, Domain, and Data. The approach includes a detailed folder structure with ViewModels, Use Cases, Repositories, and Dependency Injection modules through Hilt.
This layered structure makes it easier to unit test each component in isolation. Business logic stays separate from UI frameworks, and the strict separation of concerns reduces technical debt over time.
