Structure an Android app using Clean Architecture and Hilt by dividing it into UI, Domain, and Data layers with inward dependencies, enforcing an Android-free Domain layer, and applying structured Hilt dependency injection patterns for testable components.

The correct way to modularize a multi-module Android project is by establishing clear module boundaries that enforce inward dependencies, ensuring the Domain layer remains pure Kotlin with no Android dependencies, while reusing components across the UI and Data layers.

Yes, the Domain layer in Clean Architecture must be free of Android dependencies. It uses pure Kotlin domain models to maintain strict boundary separation and ensure the business logic remains fully testable and independent from the UI and Data layers.

Migrate an existing Android app to Clean Architecture by following a practical implementation checklist that guides refactoring into a three-layer structure with Hilt-based dependency injection, enforcing inward dependencies and an Android-free Domain layer.

Hilt limitations in a multi-module Android project involve strict boundary constraints, requiring structured patterns to maintain testable components while enforcing inward dependencies and a pure Kotlin Domain layer without Android dependencies.
