Question

我尝试将设备注册到GCM服务中。这工作，我得到我的设备的注册ID并将其存储在我的服务器上。但当我向我的设备发送消息时，没有任何影响，设备无法收到消息。

google发送消息时的响应：

{u'failure': 0, u'canonical_ids': 0, u'success': 1, u'multicast_id': 8319562714448073760L, u'results': [{u'message_id': u'0:1445751667241995%f044e3acf9fd7ecd'}]}

            }

我不知道为什么这段代码不起作用！我在另一个项目中使用此代码并在我的应用程序上获取消息，但此应用程序中的此代码用于接收消息。

我的包名可能有问题吗？：）

ir.ac.buqaen.rc

请帮我解决这个问题。

Answer 1

根据Set up a GCM Client App on Android

对于扩展 WakefulBroadcastReceiver 的现有应用，Google   建议迁移到 GCMReceiver 和 GcmListenerService 。至   迁移：


在应用清单中，将 GcmBroadcastReceiver 替换为＆＃34; com.google.android.gms.gcm.GcmReceiver＆＃34;，并替换当前的
  将 IntentService 扩展到新的服务声明    GcmListenerService

从客户端代码中删除 BroadcastReceiver 实施

重构当前 IntentService 服务实现以使用 GcmListenerService

然后，您可以参考我的以下清单文件。希望这有帮助！

def add1(x: => Int): Int = {
  x + 1
}

为什么没有从gcm收到消息
