Фоновая служба FusedLocationProviderClient для Android 9 и новее

Question

Я пытаюсь получить местоположение после каждых 10 секунд, используя FusedLocationProviderClient, однако, когда я сворачиваю приложение или прекращаю его, обновление местоположения прекращается. Ниже мой код. Прямо сейчас я использую android 9.0. Я понятия не имею, почему это происходит, любая помощь будет благодарна
