Я разрабатываю приложение, которое время от времени отслеживает местоположение пользователя (например, каждые 20 секунд) и каждую минуту отправляет эти места в веб-службы. Чтобы достичь этого, я создал структуру потребителя-производителя, где каждая задача представляет собой службу android, запущенную AlarmManagers/BroadcastReceivers. Приложение также имеет интерфейс, разработанный с помощью Phonegap и JQuery Mobile для выполнения дополнительных задач и отправки некоторых данных в службы (например, имя пользователя). Проблема возникает, когда служба, ответственная за сетевую связь, застревает в методе getInputStream() и выдает диалоговое окно Android Not Responseing. Я понимаю, что длительные операции не должны выполняться в потоке пользовательского интерфейса, но я не уверен, как решить эту проблему, учитывая мой подход, любую подсказку?Android не отвечает на запросы в службе
Ниже мое приложение манифеста и некоторый код:
