Gcm设备注册错误

Question

尝试构建一个将从服务器接收推送通知的gcm应用程序。但是当我在模拟器或真实设备上执行代码时，这就是我在LogCat上获得的内容

I/===GCMIntentService===(6977): Device registered: regId = reg number here
V/GCMBaseIntentService(6977): Releasing wakelock
V/GCMBroadcastReceiver(6977): onReceive: com.google.android.c2dm.intent.REGISTRATION
V/GCMBroadcastReceiver(6977): GCM IntentService class: com.my.app.GCMIntentService

I/===GCMIntentService===(6977): unregistered = reg number here
V/GCMBaseIntentService(6977): Releasing wakelock

任何人都可以帮助我！
