Same exception using the Reference app with lib version 2.17.1. It occured after the app went to background :

What phone model? Was the reference app configured to use a foreground service? Were beacons detectable when this happened?

The problem here is that Android 10 won't allow you to start a service from the background and you have configured the library to do so. Android 8+ generally does not allow you to keep a service running in the background, and Andorid 10+ will give you this exception if you even try to start a non-foreground service from the background.

In order to fix this, you must do one of two things to get around Android restrictions:

  1. Accept the use of the job scheduler to schedule your scans (this is the library default -- just don't turn it off by calling the same method with false.)beaconManager.setEnableScheduledScanJobs(true)

  2. Configure a foreground service notification to go with your scanning service. See instructions here
