<!-- Notification permission for proximity alerts -->
<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
<!-- Background location for proximity alerts. Android stops delivering
location to a backgrounded app within a few minutes unless it is
running a foreground service, so geolocator is given a
ForegroundNotificationConfig while proximity alerts are enabled -
that starts its GeolocatorLocationService (already declared by the
geolocator_android plugin manifest) and keeps the stream alive.
FOREGROUND_SERVICE_LOCATION is required from Android 14 onward.
Deliberately NOT declaring ACCESS_BACKGROUND_LOCATION: the foreground
service covers our case without it, and merely listing it in the
manifest makes geolocator append it to the very first permission
request - which Android 11+ silently denies, because foreground and
background location cannot be asked for in one prompt. That would
degrade first-run permissions for every user, including those who
never turn proximity alerts on. It also drags in the Play Store
background-location declaration review. -->
