Best practices for implementing Android ViewModels, specifically focused on StateFlow for UI state and SharedFlow for one-off events.

  • Works in 4 steps: UI State (StateFlow) → One-Off Events (SharedFlow) → Collecting in UI → …
  • Mobile work in your project
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Android Viewmodel is an agent skill from Moustachauve/WLED-Android. Best practices for implementing Android ViewModels, specifically focused on StateFlow for UI state and SharedFlow for one-off events.

Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with Android. The repository describes itself as: Native Android application for WLED. The licence is Apache-2.0.

When your agent uses it

  • Mobile work in your project

Example prompts

  • “/android-viewmodel”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. UI State (StateFlow)
  2. One-Off Events (SharedFlow)
  3. Collecting in UI
  4. Scope

What it can do on your machine

Read from SKILL.md and the folder at commit 7e164a8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Android Viewmodel loads about 466 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 164 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~466

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Android ViewModel & State Management

Instructions

Use ViewModel to hold state and business logic. It must outlive configuration changes.

1. UI State (StateFlow)
  • What: Represents the persistent state of the UI (e.g., Loading, Success(data), Error).
  • Type: StateFlow<UiState>.
  • Initialization: Must have an initial value.
  • Exposure: Expose as a read-only StateFlow backing a private MutableStateFlow.
    kotlin
    private val _uiState = MutableStateFlow<UiState>(UiState.Loading)
    val uiState: StateFlow<UiState> = _uiState.asStateFlow()
  • Updates: Update state using .update { oldState -> ... } for thread safety.
2. One-Off Events (SharedFlow)
  • What: Transient events like "Show Toast", "Navigate to Screen", "Show Snackbar".
  • Type: SharedFlow<UiEvent>.
  • Configuration: Must use replay = 0 to prevent events from re-triggering on screen rotation.
    kotlin
    private val _uiEvent = MutableSharedFlow<UiEvent>(replay = 0)
    val uiEvent: SharedFlow<UiEvent> = _uiEvent.asSharedFlow()
  • Sending: Use .emit(event) (suspend) or .tryEmit(event).
3. Collecting in UI
  • Compose: Use collectAsStateWithLifecycle() for StateFlow.
    kotlin
    val state by viewModel.uiState.collectAsStateWithLifecycle()
    For SharedFlow, use LaunchedEffect with LocalLifecycleOwner.
  • Views (XML): Use repeatOnLifecycle(Lifecycle.State.STARTED) within a coroutine.
4. Scope
  • Use viewModelScope for all coroutines started by the ViewModel.
  • Ideally, specific operations should be delegated to UseCases or Repositories.
