android-legacy-state
Standards for State integration with Views using Coroutines and Lifecycle. Use when managing state with ViewModels and Lifecycle-aware coroutines in Android. (triggers: **/*Fragment.kt, **/*Activity.kt, repeatOnLifecycle, launchWhenStarted)
Best use case
android-legacy-state is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using android-legacy-state should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# 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. ## References - [Flow Consumption Template](references/implementation.md)
