/**
 * Configures using a `ScanJob` run with the `JobScheduler` to perform scans rather than using a

 *
 * Calling with true on devices older than Android L (5.0) will not apply the change
 * as the JobScheduler is not available.
 *
 * This value defaults to true on Android O+ and false on devices with older OS versions.
 * Accepting the default value of false is recommended on Android N and earlier because
 * otherwise beacon scans may be run only once every 15 minutes in the background, and no low
 * power scans may be performed between scanning cycles.
 *
 * Setting this value to false will disable ScanJobs when the app is run on Android 8+, which
 * can prohibit delivery of callbacks when the app is in the background unless the scanning
 * process is running in a foreground service.
 *
 * This method may only be called if bind() has not yet been called, otherwise an
 * `IllegalStateException` is thown.
