disable foreground service scanning #1157

Closed broarr closed 8 months ago

broarr commented 9 months ago

Expected behavior

I have an application that needs to be able to toggle foreground scans on and off. I expect the foreground scans to stop when I call beaconManager.disableForegroundServiceScanning(). The documentation states that disableForegroundServiceScanning() should be called after beaconManager.unbind(this). My understanding is that the bind APIs are deprecated in favor of the newer autobind API. Is there a way to stop a foreground scan when using the autobind APIs?

Actual behavior

The scan continues without interruption.

Steps to reproduce this behavior

Create a foreground service like in the reference. Call disableForegroundServiceScanning() after the foreground scanning has begun

Mobile device model and OS version

Pixel 3a -- Android 12

Android Beacon Library version

2.19.6

Yes, you can stop scanning with a foreground service simply by calling beaconManager.stopRanging(region) and beaconManager.stopMonitoring(region) for all regions being ranged and monitored. Doing so will cause the foreground service to exit. After you have done that, you can call disableForegroundServiceScanning() and the start ranging and monitoring again.

Because the APIs to stop a service on Android are asynchronous, it will take a non-zero amount of time for the service to stop. Unfortunately there is no callback, so your best bet is to insert a delay of 100ms or so between stopping ranging/monitoring and restarting.

I will leave this issue open as a reminder to update the documentation to include the above.
