i'm using estimote sdk monitor bluetooth pings when entering , exiting regions. working correctly when had scanning , notification code in activity, app no longer in foreground stopped. i'm trying set service bluetooth scanning carries on in background until click button stop it. have activity , service classes below when try debug app not starting scanning process, message:
i/estimotesdk: com.estimote.sdk.service.beaconservice.oncreate:305 creating service d/bluetoothadapter: 811314615: getstate() : mservice = null. returning state_off for reason don't think service starting properly, i'm trying figure out why. using intentservice correctly, know stops when work done, scanning process loop shouldn't finish unless explicitly tell component. using correct type of service?
here's code:
