Android Clean Architecture

Solid reference for setting up Clean Architecture in Android and KMP projects. Covers the full stack: module boundaries with strict dependency rules (domain never depends on data or presentation), UseCase and Repository patterns, and concrete examples for Room, SQLDelight, and Ktor. The mapper pattern guidance and DI setup for both Koin and Hilt are immediately useful. What I like here is the opinionated structure, it doesn't hedge on how layers should communicate. If you're past the tutorial phase and need to organize a real multi-module Android project without reinventing every architectural decision, this gives you working patterns to copy.

Android Clean Architecture

Clean Architecture patterns for Android and KMP projects. Covers module boundaries, dependency inversion, UseCase/Repository patterns, and data layer design with Room, SQLDelight, and Ktor.

When to Activate

Structuring Android or KMP project modules
Implementing UseCases, Repositories, or DataSources
Designing data flow between layers (domain, data, presentation)
Setting up dependency injection with Koin or Hilt
Working with Room, SQLDelight, or Ktor in a layered architecture
