Я пытаюсь отправить c2dm из облака на устройство. Но я получаю некоторые ошибки, утверждающие, что
HttpsURLConnection не поддерживается средой выполнения Java для Google App Engine
Пожалуйста, дайте мне знать, как исправить эту ошибку. Большое спасибо заранее.
Ниже мой код:

System.out.println("C2DM Authorizaton Key for the cloud:"+auth);
if (auth == null)
{
System.out.println("No authorization returned");
System.exit(1);
}
sendMessage(auth);
}
