architecture

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.

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.

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.

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.

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.
