У меня есть два мероприятия и одну услуги все в одном приложенииОбмена между деятельностью и службами
деятельности2 начнет и остановить службу
activity1 является основным UI
службы имеет две предполагаемых задачи : 1- получать данные с сервера через сокет и передавать его активности1 для обновления пользовательского интерфейса
2- получать данные от активности1 и отправлять его на адрес
проблема я не был в состоянии иметь четкое представление о том, как я могу сделать данные обмена услуг с деятельностью
я прочитал о AIDL, Связывание здесь http://developer.android.com/guide/components/bound-services.html
я не мог применить его на моих кодах, даже после трех недель тяжелой работы я этого не понял !!!
спасибо!
