Android UI States Validation

Android UI States Validation

When To Use

• Use this skill when the request is about: validate android ui states, check loading empty error flow android, edge cases in android screen.
• Primary outcome: Review Android UI flows for empty, loading, error, offline, and edge-case behavior before release.
• Reach for this skill when the core question is state coverage and recovery UX, not which test framework or assertion library to use.
• This skill decides what the user should see in each branch of the state matrix. android-testing-ui only validates that design with assertions and screenshots.
• Handoff skills when the scope expands:
• android-compose-accessibility
• android-testing-ui

Workflow

1. Confirm the user-visible journey, target device behavior, and failure states that matter.
2. Build a state matrix that covers loading, content, empty, error, offline, stale-data, denied-permission, and post-action confirmation states as applicable.
3. Identify the owning screens, activities, destinations, and state holders for each branch of that matrix.
4. Validate recovery UX, accessibility, configuration changes, and back-stack behavior in the showcase apps.
5. Hand off to testing only when the missing work is about assertions or automation rather than state design.

Guardrails

• Treat loading, empty, error, offline, and permission-denied states as first-class UI states.
• Do not hide navigation or permission side effects inside reusable UI components.
• Prefer lifecycle-aware APIs over manual callback chains.
• Keep deep links, intents, and permission prompts testable and observable.
• Distinguish transient messages, persistent error states, and stale-but-usable content instead of collapsing them into one generic failure screen.

Anti-Patterns

• Assuming the happy path is enough for product flows.
• Hard-coding request codes or route strings in multiple places.
• Triggering navigation directly from repositories or network layers.
• Shipping flows without recovery UI for denied permissions or broken state.
• Using tests as a substitute for deciding what the product should show in each failure mode.

Examples

Happy path

• Scenario: Validate OrbitTasks loading, content, and success confirmation states.
• Command: cd examples/orbittasks-compose && ./gradlew :app:connectedDebugAndroidTest

Edge case

• Scenario: Exercise long content, empty lists, and sync failures in the XML fixture.
• Command: cd examples/orbittasks-xml && ./gradlew :app:connectedDebugAndroidTest

Failure recovery

• Scenario: Avoid misrouting UI validation work to accessibility or testing-only skills.
• Command: python3 scripts/eval_triggers.py --skill android-ui-states-validation

Done Checklist

• The implementation path is explicit, minimal, and tied to the right Android surface.
• Relevant example commands and benchmark prompts have been exercised or updated.
• Handoffs to adjacent skills are documented when the request crosses boundaries.
• Official references cover the chosen pattern and the main migration or troubleshooting path.
