Push уведомление не работает на 3G мобильной сети

Question

The `MainActivity` registers with GCM Server and the `IntentService` sends `RegId` to the server. Wi-Fi Push Notification is working well but when running on 3G network, the MainActivity screen looks like blank screen and goes in wait state. I have spent a lot of hours for that but does not get any solution. 

I've the updated code below work fine on 3G but Server Doesnot get RegId Shared using Application:

В MainActivity регистров с GCM сервером и отправляет IntentServiceRegId на сервер. Wi-Fi Push Notification работает хорошо, но при работе в сети 3G экран MainActivity выглядит как пустой экран и переходит в состояние ожидания. Я потратил на это много часов, но не получил никакого решения.

Answer 1

Вы пробовали тестировать его на другом устройстве с различными версиями Android? Это может быть проблемой с версией оборудования или API. Также проверьте, установлено ли значение delayWhileIdle в true. Если это так, это приведет к задержке доставки до тех пор, пока ваше устройство снова не включится. [Source.]

Если это не поможет, воспользуйтесь этим способом SO thread.

Когда вы посылаете толчок уведомление от сервера убедитесь, что НЕ включают delay_while_idle, поэтому уведомление доставлено сразу. Также убедитесь, что вы установили time_to_live на разумное значение (по умолчанию - 4 недели).
