Clean Architecture Application Layer Use Case

As Android applications grow, maintaining clean, testable, and scalable code becomes essential. That's where MVVM and ca. 🔹 MVVM (Model-View-ViewModel) Separates UI from business logic Keeps UI state inside ViewModel Improves testability and maintainability Works seamlessly with Jetpack Compose, LiveData, and StateFlow 🔹 Clean Architecture Organizes code into clear layers Business rules remain independent of frameworks Easier to scale, test, and maintain Promotes Separation of Concerns 📌 Typical Flow UI (Compose/Activity) → ViewModel → Use Cases → Repository → Data Sources (API/Database ✅ Benefits ✔ Better code readability ✔ Easier debugging ✔ Faster feature development ✔ High test coverage ✔ Long-term maintainability

Part 01 - Clean Architecture Overview

Clean Architecture vs Hexagonal Architecture explained in one image ⚖️ Both protect your business logic and make dependencies point inward. Clean Architecture organizes code in 4 concentric layers (Entities, Use Cases, Interface Adapters, Frameworks & Drivers), while Hexagonal uses a domain core surrounded by ports and adapters. Cousins, not rivals! 💡 Golden rule: same goal, protect your business logic. Different way to draw it. Save this for your next interview! 📌 👇 Which one do you prefer: Clean or Hexagonal?
