    CRITICAL: ViewModel is launching a coroutine in GlobalScope; change to viewModelScope to prevent memory leaks.
REMEDIATION:
1. Inject Dispatchers.IO for repository calls.
2. Update 'saveUserSettings' to use 'collectAsStateWithLifecycle' in Compose UI to ensure stability during config changes.

    About This Skill

    What it does

    This skill provides comprehensive engineering guidance for native Android development using Kotlin. It acts as a senior Android architect, assisting with everything from multi-module project structure and Jetpack Compose UI state management to complex background processing with WorkManager and deep API integrations.

    Why use this skill

    Building high-quality Android apps requires more than just writing code; it requires navigating a complex ecosystem of lifecycle-aware components, permission flows, and hardware constraints. Instead of generic AI advice, this skill applies strict architecture patterns (MVVM/Clean), enforces offline-first data strategies, and ensures your app adheres to Play Store release readiness standards.

    Supported tools & frameworks

    • Language: Kotlin (Coroutines, Flow)
    • UI: Jetpack Compose, Navigation
    • Data: Room, DataStore, Repository Pattern
    • Architecture: Hilt/Dagger DI, MVVM, Clean Architecture
    • System: WorkManager, Permissions API, Bluetooth/Location/Media
    • Quality: JUnit, Espresso, Play Store release checklist

    Output format

    Expect structured implementation plans covering data flow, privacy considerations, and testing strategies, or prioritized code reviews that highlight critical architectural risks and remediation steps.
