У меня есть приложение, которое использует службу определения местоположения в фоновом режиме каждые 5 минут.Мы используем Fusedlocationproviderclient в сервисе переднего плана.Он работает нормально, когда приложение открыто.
Когда я помещаю приложение в фоновом режиме или проводите, чтобы убить из фона, служба Foreground автоматически уничтожается ОС на Android 8.0 и выше.
Мы сталкиваемся с проблемой в Samsung Note 8, один плюс5т и красные ми устройства.
Пожалуйста, дайте мне знать, Как я могу реализовать сервис, совместимый для всех устройств.
Это мой класс обслуживания определения местоположения.
