Android Clean Architecture with Hilt requires structuring your app into UI, Domain, and Data layers, using annotated Hilt components to inject dependencies while enforcing strict inward dependency rules where UI depends on Domain, and Domain depends on Data.

The correct dependency direction for Android Clean Architecture is strictly inward: UI and presentation layers depend on Domain, and Domain depends on Data, ensuring separation of concerns and testability across multi-module setups.

Refactoring a monolithic Android app into modular layers involves defining clear module boundaries, applying architectural governance patterns to separate concerns, and preserving existing behavior and test coverage throughout the multi-module migration process.

Yes, Hilt works with multi-module Android projects by providing annotated components for ViewModel injection and dependency setup, integrating cleanly across clear module boundaries established by Clean Architecture layering rules.

You need to modularize your Android app architecture when scaling development across teams requires consistent project structure, strict separation of concerns, and explicit module boundaries to maintain architectural governance and testability.

Hilt limitations in Android dependency injection include managing testing considerations for annotated components and ensuring explicit dependency directions are maintained, which requires careful architecture governance during multi-module refactoring to avoid breaking layering rules.
