Android Legacy State Standards

Priority: P1 (HIGH)

Implementation Guidelines

Flow Consumption

Rule: ALWAYS use repeatOnLifecycle(Lifecycle.State.STARTED) to collect flows in Views.
Why: Prevents crashes (collecting while view 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.
