What problem does it solve? Building Android apps involves many pitfalls: Gradle misconfiguration, threading mistakes, Compose context errors, build failures, and Material Design non-compliance. This Skill provides a structured reference covering project setup, Kotlin coding standards, Compose patterns, build troubleshooting, and M3 design guidelines so developers avoid common errors from the start. ## Core Features & Use Cases - Project Configuration: Checklists for Gradle setup, gradle.properties, build variants, product flavors, and dependency management with Compose BOM. - Kotlin & Compose Standards: Null safety, coroutine threading rules, state management, lifecycle handling, and common syntax pitfalls with correct/incorrect code examples. - Build Error Diagnosis: Quick-reference tables mapping error keywords to causes and fixes, plus debugging commands like ./gradlew dependencies. - Material Design 3 Compliance: Color contrast ratios, touch target sizes, 8dp grid, typography scale, and anti-patterns, with deep-dive references for accessibility, motion, adaptive screens, performance, privacy, and testing. - Use Case: When starting a new Android app or fixing a failing build, consult this Skill to verify the project structure, configure flavors (dev/staging/prod), and ensure UI code meets Google Play quality thresholds. ## Quick Start Ask the assistant to review your Android project setup or Compose screen code against the android-native-dev guidelines before writing business logic.
