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.
