android - Using Beacon Library from background service -

i trying utilize android beacon library in app runs background service. bind beaconmanager on service starting. unbind ondestroy. want stop , start ranging based on user action (on_duty / off_duty)

i have tried several combinations on lastly week can't seem right ranging restart after have stopped it. in cases next beaconintentprocessor:

"but ranging notifier null, we're dropping it."

what right methods phone call both stop , start ranging? should not able bind , unbind service based on (on_duty / off_duty) (i have tried have not been able create work consistently)

my app personal in field using beacons periodic checkins @ different locations while on_duty , disable ble in app while off_duty conserve battery. while app in off_duty mode app still maintains background service other functionality.

below startup sequence. not sure if there problem - @ end keeps looping through same "restarting scan" sequence.

there should no problem doing want if set properly.

i suspect "ranging notifier null" because did not set ranging notifier in onbeaconserviceconnect() callback. if set ranging notifier in method, need post code can assist further.
