Android Navigation Deep Links
When To Use
- Use this skill when the request is about: android navigation graph, deep link into android app, back stack issue in compose nav.
- Primary outcome: Handle navigation graphs, back stack behavior, app links, intents, and destination ownership for Android apps.
- Handoff skills when the scope expands:
android-permissions-activity-resultsandroid-testing-ui
Workflow
- Confirm the user-visible journey, target device behavior, and failure states that matter.
- Identify the owning screens, activities, destinations, and state holders for the flow.
- Implement the flow with explicit loading, success, empty, and error handling.
- Validate accessibility, configuration changes, and back-stack behavior in the showcase apps.
- Escalate data, architecture, or release concerns to the specialized skills called out in the handoff notes.
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.
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.
Remediation Examples
Centralize route ownership
sealed interface OrbitRoute {
data object Board : OrbitRoute
data class Task(val taskId: String) : OrbitRoute
}Preserve expected back-stack behavior
navController.navigate(OrbitRoute.Task(taskId)) {
launchSingleTop = true
restoreState = true
}Parse deep-link arguments in one place
val taskId = intent?.data?.getQueryParameter("taskId")
require(!taskId.isNullOrBlank()) { "Missing taskId deep-link argument" }Examples
Happy path
- Scenario: Route the Compose showcase into a task details destination from a deep link.
- Command:
cd examples/orbittasks-compose &&./gradlew:app:testDebugUnitTest
Edge case
- Scenario: Preserve expected Up and Back behavior when the XML activity is cold-started from a link.
- Command:
cd examples/orbittasks-xml &&./gradlew:app:testDebugUnitTest
Failure recovery
- Scenario: Prevent confusion with permission, state, and release prompts.
- Command:
python3 scripts/eval_triggers.py --skill android-navigation-deeplinks
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.
