Android & KMP Engineering Suite (android)
Master playbook and router for modern Android and Kotlin Multiplatform (KMP) engineering. Covers foundation setup, design systems with live-themed in-app component galleries, gesture-driven motion, opinionated architectural patterns, and orchestration validation presets.
When to Use
- Architecting, structuring, or reviewing Android and Kotlin Multiplatform projects
- Designing with Material Design 3, building subtle in-app Component Galleries with real-time theme updates and Material You Expressive dynamic colour, and managing safe signing keys
- Implementing gesture-triggered animations (collapsing headers, bottom sheets, carousels, swipe actions, pull-to-refresh) following
interaction-driven-animation - Building with Philipp Lackner's architecture conventions (MVI presentation, type-safe Navigation Compose, Koin DI, offline-first Room/Ktor data layer, typed Result error handling, unit testing with JUnit 5 + AssertK + Turbine, and PR quizzes)
- Integrating mobile-specific verification commands (
flock /tmp/dtm-gradle.lock, APK assemble, device smoke testing) withmulti-agent-orchestration
