SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Guides developers on designing Android apps with a clean, scalable architecture and proper DI patterns, reducing maintenance overhead and onboarding time.

Core Features & Use Cases

  • Enforces a three-layer architecture (UI, Domain, Data) with inward dependencies.
  • Promotes Hilt-based dependency injection and modularization strategy.
  • Provides a recommended module layout for large apps and concrete rules for dependencies and testing.
  • Use Case: When starting a new Android project, structure modules and DI to facilitate independent testing and feature growth.

Quick Start

Follow the guidelines to scaffold a new Android project with UI, Domain, and Data layers and annotate Application with @HiltAndroidApp.

FAQPage Schema
How do I structure an Android app with clean architecture and Hilt?▼

Structure your Android app by enforcing a three-layer architecture (UI, Domain, Data) with inward dependencies and using @HiltAndroidApp for Hilt-based dependency injection. This enforces clear module boundaries and facilitates independent testing for feature growth.

What is the best way to modularize a large Android project?▼

The best way to modularize a large Android project is by following a recommended module layout that enforces clear boundaries between UI, domain, and data layers. This strategy reduces maintenance overhead and onboarding time while supporting feature growth.

When do I need a three-layer architecture for my Android app?▼

You need a three-layer architecture when starting a new Android project or scaling an existing one to facilitate independent testing and feature growth. Separating UI, domain, and data layers with inward dependencies ensures a clean, scalable structure and reduces maintenance overhead.

Does Hilt dependency injection work well with clean architecture layer separation?▼

Hilt dependency injection works well with clean architecture by providing concrete DI strategies across UI, domain, and data layers. Annotating the Application class with @HiltAndroidApp sets up the DI graph to respect clear module boundaries and inward dependencies.

Can I use this Android modularization strategy for projects of varying sizes?▼

Yes, this modularization strategy applies to Android projects of varying sizes. It provides a recommended module layout for large apps and concrete rules for dependencies and testing, ensuring a clean, scalable architecture that reduces maintenance overhead.
