我正在尝试使用GCM发送通知。 GoogleCloudMessaging部分中的注册工作正常，并生成Reg。 ID类似APA91bFZCccJh2Yt-r-9WSHk0FvmkzxCjhK9xsG2Ggc-jXNmdIg0g9Su3k5-KSL9wVd-_5CiOuqy8FKE4y7i_E6APqKsU4yTlTLmoX2pTQK25rj8JNHXcXGrd-sLDoec8GZ6jxOgtnZenzjj51eDRZMoCU_UNd1UnA
我使用此ID并向GSM发送消息。 GCM服务器的响应也很好：{"multicast_id":7600934834361287625,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1401367637744857%f2c63832f9fd7ecd"}]}
但是我的应用程序中没有收到任何消息，甚至没有调用WakefulBroadcastReceiver。以下是App端代码：
