Clean Architecture Essentials

Welcome to the hub of Clean Architecture and modern Android development practices. This repository serves as a practical guide to implementing MVVM, StateFlow, Retrofit, Dagger-Hilt, and Coroutines within the Clean Architecture.

Why Embrace an Architecture?

Imagine architecture as the blueprint for your application's future. Without it, small projects might survive the chaos, but as complexity grows, so does the need for a solid plan. Here’s why you need it:

• Complexity Management: As your project scales, a robust architecture becomes the backbone that supports and organizes its growing body of code.
• Future-proofing: Adaptability to future requirements and technologies is baked right into architectural design.
• Team Collaboration: A shared architectural language and structure mean new developers can onboard quickly and contribute effectively.

Demystifying Clean Architecture

At its core, Clean Architecture organizes code in a way that separates concerns based on their level of abstraction and dependencies.

• Abstraction Principle: Imagine concentric circles, with the innermost being the most abstract, housing your business logic, while the outer layers deal with concrete implementations like UI and database interactions.

• Dependency Rule: This is the secret sauce. Each layer can only interact with its immediate inner neighbor. This inward-only dependency flow fortifies the architecture's integrity and flexibility.

Advantages of Architectural Discipline

• Decoupling: Each part of the system is independent, testable, and reusable.
• Predictability: There's a place for everything, and everything in its place, making the codebase easier to navigate and understand.

The SOLID Foundation

SOLID principles are the pillars of Clean Architecture, ensuring that software design is robust and maintainable:

• Single Responsibility: One component equals one responsibility.
• Open-Closed: Extend functionalities without altering existing code.
• Liskov Substitution: Base classes can be substituted with their derived classes without affecting the application.
• Interface Segregation: Prefer small, specific interfaces over broad, sweeping ones.
• Dependency Inversion: Rely on abstractions, not concretions, and invert the traditional dependency relationship.

Clean Architecture is tailored to maximize these principles.

Layered Approach to Clean Architecture

The beauty of Clean Architecture lies in its flexibility. You can adapt the number of layers as needed:

• Presentation: Where the UI magic happens.
• Use Cases: Defined user-triggerable actions.
• Domain: The realm of business logic.
• Data: The abstract definition of data sources.
• Framework: The concrete implementations and Android SDK interactions.

Note: Green layers are Android SDK dependent.
