当我向设备发送通知时，该设备会收到推送消息，但它会收到“com.google.android.c2dm.intent.REGISTRATION”意图，而不是“com.google.android.c2dm.intent.RECEIVE” . 如果我尝试发送第二个通知，我会收到来自 Google 的“未注册”错误。
该设备注册良好（我猜），因为我得到了 Auth 令牌“APA91 ... -119 个字符-”。
这是我开始注册设备的代码：
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
registrationIntent.putExtra("sender", "EMAIL");
startService(registrationIntent);

/* SENDING THE AUTH TOKET TO SERVER */
}
}
我在设备上进行推送通知，因为如果我在服务器端进行，我总是会收到“InvalidRegistration”错误。
奇怪的是，我好像注册了，但是当我发送一条推送消息时，就像谷歌取消注册设备一样。
有什么想法/建议吗？
