Network location is polled instead of using NetworkCallback

**Home Assistant Android app version(s): 2026.6.5-minimal (F-Droid)**

**Android version(s): Android 15/LineageOS 22.2**

**Device model(s): Motorola G7 (river)**

**Home Assistant version: 2026.5.4**

**Description of problem, include YAML if issue is related to notifications:**

The app is constantly (every 30s or so) accessing location service (even if it is told not to: Remote connection security level → Less secure: Do not allow this app to know whey you are home). This may or may not impact battery life. However it definitely is annoying when a the notification area at the top of the screen is brought to front on top of a full screen app (e.g. a video player) with a green bubble indicating access to the location service.

I am not an Android developer, but there seem to be [a better way](https://developer.android.com/develop/connectivity/network-ops/reading-network-state?hl=en) for an app to know network connectivity status than polling every half a minute.

Syncthing is an app I use daily which [appears to be using this API](https://github.com/chenxiaolong/BasicSync/blob/cd0fbad38eb9699323ce2aacee868bf2bfa5ee25/app/src/main/java/com/chiller3/basicsync/syncthing/DeviceState.kt#L349) and indeed it works as advertised with regard to detecting network conditions and I haven't seen it polling like HA.

Start by tracing the app's network-connectivity polling and compare it with the Android NetworkCallback guidance linked in the report. Reproduce the roughly 30-second location accesses on Android 15/LineageOS 22.2, then verify that connectivity changes are detected without periodic polling and that the unwanted location indicator no longer appears.
