But `docs/manual-qa-checklist.md`'s TalkBack pass only ever exercised the *static* +banner (already offline when the screen loads) — the *transition* case (going offline while the +screen is already open, or coming back online) requires an explicit live-region / announcement +API call, which nothing in the codebase was making. + +## What changed + +- **Android** (`Screens.kt`, `VaultListScreen`): added a `LaunchedEffect(state.isOffline)` that + compares against the previous value (via a `remember { mutableStateOf(null) }`) and + calls `View.announceForAccessibility(...)` only on an actual transition, skipping the initial + composition. Announces `"Offline — showing cached data"` and `"Back online"`. +- **iOS** (`Views.swift`, `VaultListView.body`): added + `.onChange(of: vaultStore.vaultsCacheAge == nil)` calling + `UIAccessibility.post(notification: .announcement, argument:)` with the same two messages. + SwiftUI's `onChange` already only fires on an actual value change, so no manual "is this the + first render" tracking is needed on this side. +- **`docs/manual-qa-checklist.md`**: added an explicit checklist item under the TalkBack/VoiceOver + pass to go offline→online→offline and confirm both transition announcements fire (not just the + initial banner appearance), plus a note that the WebSocket connection-status indicator proposed + in issue #254 doesn't exist in the codebase yet — when it's built, it should reuse this same + announce-on-transition pattern for its connecting/connected/reconnecting states. + +## Why a documented manual step instead of an automated test + +`announceForAccessibility` / `UIAccessibility.post` fire real platform accessibility events that +aren't observable from a JVM-only Robolectric/Paparazzi test or a SwiftUI preview — verifying they +actually reach TalkBack/VoiceOver requires either a real accessibility-service listener in an +instrumented test (heavier than this fix warrants) or a manual pass. The checklist step above +covers it manually for now; wiring an `AccessibilityEvent` listener into +`AccessibilityScanTest.kt` (added in the touch-target-audit change) is a reasonable follow-up. diff --git a/docs/touch-target-audit.md b/docs/touch-target-audit.md new file mode 100644 index 0000000..922d959 --- /dev/null +++ b/docs/touch-target-audit.md @@ -0,0 +1,25 @@ +# Touch Target Audit (Issue: Accessibility — minimum tap target size) + +Audit of interactive controls in `Screens.kt` (Android) and `Views.swift` (iOS) against the +platform minimum touch target sizes: 48x48dp on Android, 44x44pt on iOS. + +## Findings + +| Control | File | Before | After | +|---|---|---|---| +| `StatusChip` (VaultCard status row) | `Screens.kt` | `SuggestionChip` default height ~32dp — below the 48dp minimum | Wrapped in a `Box(Modifier.sizeIn(minWidth = 48.dp, minHeight = 48.dp))` to guarantee a 48dp tap target while keeping the compact visual size | +| Top bar `IconButton`s (Add vault, overflow menu, back) | `Screens.kt` | Material3 `IconButton` defaults to 48dp — compliant | No change needed; confirmed via audit | +| Deep-link screen "Done" `IconButton` | `Screens.kt` (lines ~961, ~1097, ~1422) | Material3 default — compliant | No change needed; confirmed via audit | +| Notification inline "Check In" action | `NotificationHelper.kt` | Rendered by the OS notification shade, not app layout | Out of app control; platform (Android System UI) is responsible for the tap target of `NotificationCompat.Action` | +| iOS toolbar buttons (`Image(systemName:)`, `Label`) | `Views.swift` | SwiftUI toolbar buttons default to a 44pt minimum via `.contentShape`/system button styling | Confirmed compliant; no change needed | + +## Follow-up + +- The `StatusChip` fix is the only code change required by this audit; it was the one dense-row + control (VaultCard) called out explicitly in the issue. +- See `.github/workflows/android-ci.yml` (`accessibility-scan` job) for the new automated guard + against regressions, using the Android Accessibility Test Framework (ATF) via Espresso's + `AccessibilityChecks.enable()`. +- iOS: Xcode's Accessibility Inspector does not currently expose a scriptable CLI target suitable + for CI. `xcrun simctl` + `axclient` automation is tracked as a follow-up; until then, the + `docs/manual-qa-checklist.md` TalkBack/VoiceOver pass covers this manually on iOS. diff --git a/ios/EthosProtocol/Sources/Views/Views.swift b/ios/EthosProtocol/Sources/Views/Views.swift index 43245c2..17ea38d 100644 --- a/ios/EthosProtocol/Sources/Views/Views.swift +++ b/ios/EthosProtocol/Sources/Views/Views.swift @@ -386,6 +386,16 @@ struct VaultListView: View { .onChange(of: vaultStore.pendingDeepLink) { _, link in if link != nil { showDeepLinkSheet = true } } + // #a11y-live-region: the offline banner being labeled isn't enough — VoiceOver only + // announces a view on first appearance or on an explicit accessibility notification. + // vaultsCacheAge flipping between nil (online) and non-nil (offline) needs an + // explicit UIAccessibility.post(notification: .announcement) so the transition + // itself — not just the banner's static label — reaches a VoiceOver user, matching + // the Android-side announceForAccessibility fix in Screens.kt. + .onChange(of: vaultStore.vaultsCacheAge == nil) { wasOnlineBefore, isOnlineNow in + let message = isOnlineNow ?
