我正在尝试使用谷歌云移动后端应用程序设置我的第一个 android 应用程序。我或多或少地运行了它，但我无法发送任何消息。它在这里停止并出现以下错误。

关于如何使它工作的任何建议？我已经尝试了这个问题的两种解决方案，它们相似但没有运气。谷歌应用引擎示例应用程序抛出 503

V/GCMBroadcastReceiver(26229): onReceive: com.google.android.c2dm.intent.REGISTRATION
V/GCMBroadcastReceiver(26229): GCM IntentService class: com.google.cloud.backend.android.GCMIntentService
V/GCMBaseIntentService(26229): Acquiring wakelock
D/GCMBaseIntentService(26229): handleRegistration: registrationId = null, error = INVALID_SENDER, unregistered = null
D/GCMBaseIntentService(26229): Registration error: INVALID_SENDER
V/GCMBaseIntentService(26229): Releasing wakelock
W/AbstractGoogleClient(26229): Application name is not set. Call Builder#setApplicationName.
