Found on the Android 12 emulator: after the doses on an alarm screen were marked Taken on Today, the alarm screen stayed open behind. Snooze there re-armed alarms for doses already taken, so they rang again ~10 minutes later.

Fix

Every "answered elsewhere" path (Today's Taken/Skip, the missed-dose notification's Taken/Skip, restore, deleting a medication) ends in AlarmScheduler.cancel → AlarmService.cancelFallback — the same path PR #37 uses to take a dose off the fallback list. cancelFallback now also calls AlarmActivity.dropDoses:

• the open alarm screen (at most one, singleInstance) removes those doses from its list and redraws;
• with none left, it closes;
• its intent extras are updated too, so a recreated screen (rotation) doesn't bring them back.

Because the screen's list is what Taken/Snooze act on, they now only touch doses still pending.

It only ever drops doses positively answered elsewhere, never guesses "not pending" — wrongly dropping a dose on Snooze would mean it never rings again.

Testing

• flutter analyze clean, flutter test (also TZ=Europe/Warsaw) passing, debug APK builds.
• Kotlin-only path: no Dart test covers it. The repo has no Kotlin unit tests, and an Activity test needs Robolectric or a device. Not run on a device yet — manual steps are in AGENTS.md (two meds at the same minute → alarm screen → Home → Taken on Today one at a time).

Summary by CodeRabbit

• Bug Fixes
  • Alarm screens now update when doses are handled elsewhere, removing those doses from the open screen. The screen closes automatically when no doses remain, helping prevent outdated reminders from lingering.

Walkthrough

When a dose is handled elsewhere, fallback cancellation now removes it from the open alarm screen. The screen refreshes with remaining doses and closes when none remain. The change also preserves the medication-name text size when the display returns to one dose.

Changes: Alarm dose updates

Layer / File(s)	Summary
Track and update the open alarm screen android/app/src/main/kotlin/dev/susiee/dosekeeper/AlarmActivity.kt	AlarmActivity tracks the active screen, removes handled doses from its displayed and intent-held lists, and finishes when the list is empty. It restores the medication-name text size when one dose remains.
Connect fallback cancellation to the alarm screen android/app/src/main/kotlin/dev/susiee/dosekeeper/AlarmService.kt, AGENTS.md	cancelFallback now calls AlarmActivity.dropDoses for the canceled dose.

Merge Risk: Moderate · previous review 7e9f1

Marking a dose as taken elsewhere now removes it from the open alarm screen in the normal case. If Android restores the screen after process death, the old dose list can return and Snooze can re-arm an already-answered dose. Consider fixing this before merge, or accept it knowingly. Manual device testing is still outstanding.

Security architecture risk: Low · up to 7e9f1

The change keeps an open medication alarm consistent with doses handled elsewhere. Its effects remain limited to the app’s existing alarm controls on one device, with no demonstrated expansion of external access. Activity recreation and interruption behavior still lack runtime verification.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The added authority is limited to removing matching doses from the app’s registered alarm screen on the current device. It does not itself grant access to another application, remote service, or additional data store.

Trust Boundaries and Controls

• observed — AlarmActivity, AlarmService, and the missed-dose action receiver remain non-exported. Notification actions use explicit immutable PendingIntents, and the receiver validates the dose ID and accepted action before cancellation. These existing controls are unchanged by the PR.

Resilience and Maintainability Implications

• inferred — Current receiver and default method-channel callbacks serialize cancellation with activity events on the main thread, supporting consistent list ownership. The new forwarding API does not enforce that thread requirement itself, so future callers must preserve the existing execution contract.

Explanation

The title names the main change: the alarm screen now removes doses that were answered elsewhere and closes when no doses remain. The raw summary shows AlarmActivity.drop and dropDoses, and AlarmService.cancelFallback notifying the open screen, which match the title. The title is specific and concise, and it does not use vague terms. It is 69 characters, which is within a normal length for a title.

Preserve removed doses across process restoration.

If Android restores the screen after process death, it can restore the original dose list. Snooze can then re-arm an answered dose.

Persist the removals and apply them on restoration. Include removals made while the screen is stopped, and keep doses whose status is unknown.

Valid, fixed in 9879a6b. Answered ids are now saved (own prefs file, pruned after 2 days). The screen filters them out in onCreate (so a screen rebuilt after process death drops them, and closes if none are left) and again right before Taken/Snooze act, so Snooze can't re-arm one. Unknown doses are kept: only ids positively answered via cancelFallback are dropped. An id is cleared again whenever its alarm fires (AlarmReceiver) or rings (AlarmService.startRinging, which also covers a START_REDELIVER_INTENT ring), so a ringing dose is never hidden from the screen that stops it.

@SusieeTheLinuxUser The fix covers restoration while the answered ID remains in preferences. I found one remaining case in AlarmActivity.kt at Line 193:

1. A screen’s process dies, and its dose is answered elsewhere.
2. More than two days later, another dose is answered, which prunes the first ID.
3. If Android restores the original screen, Snooze can re-arm the first dose.

Please retain the answered state until the stale screen can no longer be restored, or use another durable check. Please also test restoration after pruning. I checked the code but did not run a device test.

# DoseKeeper — continuation brief

## Prior state (2026-09-20)

### Implemented

- **Native alarm layer** (`android/app/src/main/kotlin/dev/susiee/dosekeeper/`)
  - `AlarmScheduler.kt` — `AlarmManager.setAlarmClock()`. Chosen deliberately: it is the
    only alarm API Android treats as a genuine user alarm clock (Doze-exempt, App
    Standby-exempt, shows in the status bar). Do not "simplify" this to `setExact` or WorkManager.
  - `AlarmService.kt` — foreground service that rings. Plays on the **alarm** audio stream
    (audible on silent/vibrate), raises volume if muted, loops, vibrates, holds a wake lock,
    `START_REDELIVER_INTENT` so it comes back ringing if killed mid-ring.
  - `AlarmActivity.kt` — native full-screen alarm over the lockscreen, turns the screen on.
    Native (not Flutter) on purpose: must appear instantly from a cold process. Back button
    is intentionally a no-op. Writes TAKEN/SNOOZE to SharedPreferences.
  - `AlarmReceiver.kt` / `BootReceiver.kt` — receiver hands straight off to the service
    (~10s limit); boot receiver re-arms every alarm from `AlarmScheduler`'s native
    registry (incl. OEM quickboot actions) -- see "Earlier: reboot audit" for why.
  - `MainActivity.kt` — MethodChannel `dev.susiee.dosekeeper/alarms`.

- **Reliability over everything.** Never weaken the alarm path (alarm stream, foreground
  service, full-screen intent, `setAlarmClock`) for cleanliness or battery friendliness.

Fixed in 5ef73eb: the screen saves when it first opened in its instance state (kept by the system across process death). A rebuilt screen older than the 2-day answered window closes itself instead of offering Snooze, so a pruned id can't be re-armed through one. Its doses are long past the 2h missed grace by then, and the missed-dose notification covers them. Not device-tested (no device on this run); manual steps are in AGENTS.md.

@SusieeTheLinuxUser Code inspection supports the fix. If Android restores the saved openedAt value, the screen closes when it is older than the answered-ID retention window.

The requested restoration-after-pruning test is still pending. When an emulator is available, please kill the backgrounded process, answer a dose, trigger pruning after two days, and restore the screen. Confirm that it closes without offering Snooze.
