我正在使用GCM实现推送通知。我已经成功获取到令牌和实例ID，服务器发送通知也返回成功，但我无法在手机上接收通知。请帮忙解决!!!

以下是我的代码

你在onMessageReceived()方法中收到消息了吗？ - Pankaj

你来自乌代布尔吗？ - Pankaj

@Clairvoyant 不会帮助我，除非我来自乌代布尔？？？ - Neha Tyagi

请在您的清单文件中添加以下内容以使用自定义权限： <permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE" android:protectionLevel="signature" /><uses-permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE" />  <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> - Pankaj

将权限更改为以下内容并检查。

<!-- Creates a custom permission so only this app can receive its messages. --> 
    <permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE" android:protectionLevel="signature" /> 
    <uses-permission android:name="YOUR_PACKAGE_NAME.permission.C2D_MESSAGE" /> 
    <!-- This app has permission to register and receive data message. -->
     <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

- Pankaj

从您提到的“服务”中删除“清单”中的“导出标记”。 - Pankaj

我写的代码可以工作..不需要移除任何内容。 - Neha Tyagi

我已经找到了解决我的问题的方法。

首先，我纠正了我的应用程序中的这些权限，尽管新版本不会出现问题。

 <permission
    android:name="com.example.appname.permission.C2D_MESSAGE"
                                android:protectionLevel="signature" />

        <uses-permission android:name="com.example.appname.permission.C2D_MESSAGE" />

第二，问题在于Wi-Fi隐私。当我使用公司的Wi-Fi时，手机无法接收信息，因为GCM服务器端口被阻止。

您可以使用以下链接有效地实现GCM：

https://developers.google.com/cloud-messaging/ https://github.com/codepath/android_guides/wiki/Google-Cloud-Messaging

快乐编程 :)

不错的发现。我听说你可以阻止GCM服务器端口。很酷。 - Pankaj

谢谢。如果我没有解决这个问题，我就永远不会收到通知了。 - Neha Tyagi

你需要在清单文件中编写

<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />

其中com.example是您的包名。

但您的应用程序包名是com.example.appname

因此，您需要编写

<permission android:name="com.example.appname.permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
 <uses-permission android:name="com.example.appname.permission.C2D_MESSAGE" />
