Checking that the SKILL.md file is still in the repository.
Build and migrate Android apps with Kotlin, Jetpack Compose, MVVM, Hilt, Room 3 (KSP, SQLiteDriver, Flow/suspend DAOs), Navigation3, and multi-module Gradle. Use for new projects or modules, Compose screens and ViewModels, Room 3 and RemoteMediator, API 37 / targetSdk migration, Play Integrity client wiring, offline-first sync, and version-catalog alignment. Not for iOS, Flutter, React Native, KMP-only shared code without an Android app module, or backend-only APIs with no Android client.

Android Kotlin Compose Development
Context ladder (smaller load first; full references stay complete):
- This file (
SKILL.md) - routing, stop rules, examples. references/*-quick.mdwhen listed below - required/forbidden + section links (~40 lines).- One target section in the full
references/*.md- code samples and checklists only. - INDEX-sections.md - anchor dump only when quick routing is insufficient.
Forbidden: load INDEX-sections.md or an entire multi-thousand-line reference when one section or a quick file covers the task.
Route tasks through the Quick Reference table. When no row matches, or the task needs greenfield bootstrap: workflows.md. Full file list: INDEX.md.
Required:
- Existing project: read
settings.gradle.kts,gradle/libs.versions.toml, and theappmodule build file before copying fromassets/- dependencies.md, modularization.md. Stack migrations: migration.md. - Greenfield: workflows.md → "Creating a new project?"
- After module, DI, navigation, Room schema, or AGP/Kotlin/KSP changes:
./gradlew helpthen:app:assembleDebug(use the real app module name) - gradle-setup.md.
Outside-repo stop rules (do not substitute repo edits): Play upload, tracks, rollout, versionCode - android-ci-cd.md; Play Integrity prerequisites (Console/Cloud setup) - android-security-quick.md; production adb install / pm clear - testing.md.
