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

  • launchWhenX: 
    **Deprecated**: Use repeatOnLifecycle.
  • observe(this): 
    **Leak Risk**: Use viewLifecycleOwner in Fragments.
