Я пытаюсь создать приложение, которое отслеживает перевозчика и показывает его на карте. Сначала я попытался получить местоположение backgroun, и мне это удалось, но в видео, которые я смотрю, никто не объясняет, как отправлять данные из службы в действие. Кто-нибудь может мне в этом помочь? Вот мой Сервис и основная деятельность. Мне нужно измерить широту и долготу в режиме основной активности.
