У меня проблема при получении push-уведомления на стороне сервера.Я использую соединение C2DM для получения push-уведомления.Его отлично работает на Android, но не в Java Servecr.Я могу получить регистрационный идентификатор и код аутентификации, но обработка останавливается, когда дело доходит до строки:
OutputStream out = conn.getOutputStream();
Он ничего не выдает, просто останавливается.
Если у кого-то естьрешение для этого, пожалуйста, направьте меня.Я добавляю весь код, чтобы вы могли пройти и сказать мне, где я неправ в получении результата.
