Integrate State with Views using Coroutines and Lifecycle on Android. Use when managing state with ViewModels and Lifecycle-aware coroutines in Android. (triggers: **/*Fragment.kt, **/*Activity.kt, repeatOnLifecycle, launchWhenStarted)
Android Legacy State Standards
Priority: P1
Implementation Guidelines
Flow Consumption
Rule: ALWAYS use repeatOnLifecycle(Lifecycle.State.STARTED) to collect flows in Views.
Why: Prevents crashes (collecting while view is destroyed) and saves resources (stops
collecting in background).
LiveData vs Flow
New Code: Use StateFlow exclusively.
Legacy: If using LiveData, observe with viewLifecycleOwner (Fragment), NOT this.
Anti-Patterns
No launchWhenStarted/Resumed: Deprecated. Use repeatOnLifecycle instead.
No observe(this) in Fragments: Use viewLifecycleOwner to prevent lifecycle leaks.
