GCM: Cihaz ileti gönderebilir, ancak kayıtlı değil

Question

Şu anda gcm'ye dayanan bir android uygulaması yapıyorum. Gerçek cihazda çalıştırdığımda, herhangi bir hata göstermedi ve mesaj gönderebilirim (GAE günlükleri de gösterir/gönderme ifadesi). Sorun başka bir cihaz herhangi bir mesaj almadı. GAE günlüklerine bakın ve herhangi bir/register ifadesini gösterme işlemini yapar. Emulator üzerinde çalışırken bu hatayı alırım.

Not: Ben buna geldiğinizde ben ... gcm.register de kayıt üzerinde yatay bir çizgi fark, onun @RequiresPermission (değer = "com diyor. google.android.c2dm.permission.RECEIVE ") @ Gözden geçirilmiş

Zaten Android manifest'teki izinlerden de bahsetmiştim ancak hala satır gitmedi.

öğretici çok eski. yolda google geliştiricilerin mesajı kontrol edin:()

GCM kayıt 28 Mayıs başlayarak itiraz edildi, kayıt jeton oluşturulması, döndürme ve güncellenmesi ele örneği kimliği API'sini kullanmalıdır 2015 Yeni uygulama geliştirme.

Yani onun google geliştiricilerin bu kılavuzu takip etmek önerilir:
