我正在我的应用程序中实现推送通知服务，我遵循了教程on Android developers.com，但是很遗憾，我没有收到任何通知。
我成功接收到注册ID，但是，尽管后端服务收到了成功的响应，但该设备未从后端收到任何通知。
p.s：我确定从后端服务的实施中就可以将通知发送到Google云服务器。
任何人都可以帮助我解决这个问题..？，先谢谢您。
下面您可以找到我的实现。

整个清单中的软件包名称都不匹配：
应用程序包：
package="com.ettamen.app"
在权限中，您应该使用应用程序的软件包，但使用的是：
<permission
android:name="com.ettamen.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.ettamen.permission.C2D_MESSAGE" />
两者都应为com.ettamen.app.permission.C2D_MESSAGE。
最后，广播接收器：
<receiver
android:name="com.ettamen.app.pushnotifications.CordovaGCMBroadcastReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.ettamen.app.pushnotifications" />
</intent-filter>
</receiver>
类别应包含您的应用包名称，因此应为com.ettamen.app。
经过大量的试验，我发现问题是，只要清单中其意图过滤器的类别包含应用程序的主程序包，接收方就可以位于您喜欢的任何程序包中
谢谢大家的帮助和支持。
