Subscribe change not Working When App is Closed

[krisnapy]

Hello,

I've encountered an issue where the subscribe change functionality does not seem to work when the app is closed. I've already ensured that the following settings are enabled:

1. HealthKit Background Delivery
2. Background Fetch
3. Background Processing
4. Background Notification

Despite these configurations, changes are not being delivered as expected when the app is completely closed. Is there an additional step or configuration I might have missed to enable background HealthKit updates effectively?

const initAppleHealthKit = async () => {
  let unsubscribe: any = null

  try {
    await HealthKit.requestAuthorization(AUTHORIZATION_OPTIONS)
    await HealthKit.enableBackgroundDelivery(HKWorkoutTypeIdentifier, HKUpdateFrequency.immediate)

    unsubscribe = await HealthKit.subscribeToChanges(HKWorkoutTypeIdentifier, () =>
      BackgroundService.start(getWorkoutSamples, {
        taskName: 'ImportWorkout',
        taskTitle: t('Import workout...'),
        taskDesc: t('Please wait for the import workout to finish.'),
        taskIcon: {
          name: 'ic_notification',
          type: 'drawable',
        },
        color: palette.brandPrimary,
      })
    )
  } catch (error: any) {
    handleGenericError(error)
  }

  return () => unsubscribe()
}

Is this potentially a duplicate of #106?

Thank you for your response!

Just to clarify, the package works fine when the app is in the background, as long as the app is not completely closed or killed.

@krisnapy Thanks for clarifying! I think this is probably a limitation on Apples side, they tend to restrict background tasks in general when an app has been forcefully killed.
