Summary

This PR removes background geolocation from the IC app and updates the Android foreground service configuration to match the app’s remaining foreground-only location and calling behavior.

What changed

Removed background geolocation from the app

  • The app no longer exposes a background geolocation setting in Settings.
  • Startup logic no longer loads background geolocation state.
  • Background geolocation hooks, storage usage, and related state were removed.
  • Legacy stored background geolocation keys are now cleaned up on startup so upgraded installs do not retain obsolete data.

Converted location handling to foreground-only

  • The location service now requests only foreground location permission.
  • Background location tasks and task-manager integration were removed.
  • Location tracking now runs only while the app is active/open.
  • When the app goes to the background, the active location subscription is removed; when the app returns to active state, tracking resumes only if it had already been requested.
  • The app continues to store location locally for in-app use, but does not perform background location tracking.

Blocked background-location permissions from shipping

  • Android config now explicitly blocks:
    • ACCESS_BACKGROUND_LOCATION
    • FOREGROUND_SERVICE_LOCATION
  • Expo location plugin configuration was changed to remove “always” location permission prompts and other background-related location settings.
  • A new manifest plugin removes the location task service contributed by expo-location, preventing a location-typed foreground service from appearing in the merged Android manifest.
  • iOS “always” location permission entries are also removed from the generated configuration.

Adjusted Android foreground service declarations

  • The custom Android manifest foreground service type for Notifee was changed to remove mediaPlayback, leaving microphone/connected-device service types.
  • LiveKit foreground service notifications now declare microphone and connected-device foreground service types.

Simplified boot receiver handling

  • Boot receiver overrides were narrowed to notifications-related receivers only.
  • Task-manager boot receiver handling was removed since background location/task manager support is no longer part of the app.

Functional impact

  • The app now supports location usage only while open and in use.
  • It no longer ships background location capabilities or related permissions.
  • Android foreground service declarations were updated to better reflect the app’s active calling/audio device use without advertising unnecessary location or media playback background capabilities.

Review Change Stack

📝 Walkthrough

Walkthrough

The change removes background geolocation support. Location tracking now runs only while the app is foregrounded. Legacy state is migrated and cleaned up. Expo and Android configuration block background-location permissions and services.

Changes

Background location removal

Layer / File(s) Summary
Foreground location lifecycle
src/services/location.ts, src/services/__tests__/location.test.ts, src/lib/hooks/*
LocationService now manages foreground subscriptions and app-state restarts. Background permissions, tasks, and updater APIs were removed.
State and storage cleanup
src/stores/app/location-store.ts, src/lib/storage/legacy-keys.ts, src/app/_layout.tsx, src/app/(app)/settings.tsx, src/translations/*.json
Background-location state, settings UI, translations, and storage APIs were removed. Persisted state migrates to version 1, and obsolete storage keys are deleted at startup.
Foreground-only native configuration
app.config.ts, plugins/withoutBackgroundLocation.js, plugins/withRestrictedBootReceivers.js, plugins/__tests__/*, customManifest.plugin.js, src/stores/app/livekit-store.ts, jest-setup.ts
Expo and Android configuration block background-location permissions and services. Android foreground services use microphone and connected-device types. Manifest and boot-receiver tests were updated.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 26e79

The change removes background geolocation and keeps foreground location tracking, but rapid active/background transitions can leave a watcher running while backgrounded or orphan a duplicate watcher. This is a bounded correctness risk, so the PR is mergeable with explicit owner awareness and follow-up to serialize startup and re-check state after awaits.

kody code-review Bug medium

Stale state in src/services/location.ts: startLocationUpdates sets isTrackingRequested before permission and watcher creation succeed, so a denied initial permission causes handleAppStateChange('active') to see a stale true value and repeatedly retry startLocationUpdates on every foreground return from the map screen. Set isTrackingRequested = true only after permissions are granted and a watcher is created, or clear the flag before throwing Error('Location permissions not granted') or returning from startup failure.

  async startLocationUpdates(): Promise<void> {
    // On web, use a lightweight browser geolocation watcher instead of expo-location
    if (isWeb) {
      if (!('geolocation' in navigator)) {
        logger.warn({ message: 'Geolocation API not available in this browser' });
        this.isTrackingRequested = false;

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard startLocationUpdates against interleaved app-state transitions.

startLocationUpdates has two awaits (requestPermissions, watchPositionAsync) before it assigns this.locationSubscription. handleAppStateChange calls it on every active event and calls removeSubscription on every background event. Two interleavings produce wrong state:

  • background arrives while a start is in flight: removeSubscription sees locationSubscription === null and returns. The pending watchPositionAsync then assigns a live watcher, so the app keeps a foreground watcher while backgrounded until the next background event.
  • Two active events in quick succession: both calls pass the !this.locationSubscription check and create two watchers. The second assignment overwrites the first, which is never removed.

Track the in-flight start and re-check intent after the awaits.

♻️ Proposed guard
-  async startLocationUpdates(): Promise<void> {
-    this.isTrackingRequested = true;
+  private startPromise: Promise<void> | null = null;
+
+  async startLocationUpdates(): Promise<void> {
+    this.isTrackingRequested = true;
+
+    if (this.startPromise) {
+      return this.startPromise;
+    }
+
+    this.startPromise = this.doStartLocationUpdates().finally(() => {
+      this.startPromise = null;
+    });
+
+    return this.startPromise;
+  }
+
+  private async doStartLocationUpdates(): Promise<void> {

Then, after watchPositionAsync resolves, drop the watcher if the intent changed:

const subscription = await Location.watchPositionAsync(/* ... */);

if (!this.isTrackingRequested) {
  subscription.remove();
  return;
}

this.locationSubscription = subscription;

handleAppStateChange must also clear isTrackingRequested intent only in stopLocationUpdates, so set a separate isForegrounded flag for the background branch if resume-after-background must keep working.

re-check the tracking intent after each await and remove any watcher created

kody code-review Bug high

Race condition in src/services/location.ts lets queued startLocationUpdates() calls survive stopLocationUpdates() because doStartLocationUpdates() does not recheck isTrackingRequested after dequeuing at src/services/location.ts:99-100. Guard the dequeued attempt with if (!this.isTrackingRequested) return; before permission requests, or use a stop-sensitive token that rejects starts queued before the current stop generation.

const attempt = this.startQueue.then(async () => {
  if (!this.isTrackingRequested) {
    return;
  }
  await this.doStartLocationUpdates();
});
this.startQueue = attempt.catch(() => {});
return attempt;
}

Unhandled promise rejection risk in src/services/location.ts because await subscription.remove() performs async cleanup without error handling. Wrap await subscription.remove() in a try/catch so cleanup failures can be logged with operation: 'doStartLocationUpdates' context.

Insufficient diagnostic context in src/services/location.ts because the logger.info call for "Location start cancelled while requesting permissions" omits structured identifiers needed for correlation. Include operation: 'doStartLocationUpdates' and generation in the log context.
