Android - LocationListener / onProviderDisabled ...... когда устройство выключает экран, SDK = 28

Question

проблема: LocationListener / onProviderDisabled = true, когда устройство выключает экран

- проблема возникает только в SDK 28.

-SDK <28 без проблем . </p>

- мобильный телефон с выключенным экраном и подключенным к Android Studio USB, без проблем.

- для проверки я создал mediaPlayer.setLooping (true) ... он не останавливается даже при выключенном экране.

- при включении экрана автоматически onProviderEnabled = true.

- Мне нужно каждую минуту отслеживать местоположение доставщика мотоцикла.
