无法从Notification Server发送的GCM接收通知

Question

我正在尝试为Android应用程序实现通知服务器。 我遵循了http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/教程，它的工作正常。 但是现在，服务器端的整个事情都由我的通知服务器处理，我在用户登录时与我共享设备ID和用户ID。 我的通知服务器已成功将regid发送到gcm，但是我没有在设备上收到通知。 我的onReceive（）现在没有被调用。 这是我的服务器从gcm收到的响应。 messageId = 0：1463550332634647％fd0791fdf9fd7ecd

配置文件

public interface Config {

//static final String APP_SERVER_URL = "http://192.168.100.27:8081/GCMServer/GCMNotification?shareRegId=1";//earlier it was used to share regid with server

如果您从GCM服务器收到如下所示的成功消息，则必须收到设备通知

来自GCM服务器的成功消息

{
    "multicast_id": 661164****4469281,
    "success": 1,
    "failure": 0,
    "canonical_ids": 1,
    "results": [{
        "registration_id": "APA91bFWKKC4Bh_B******-H",
        "message_id": "0:14635506***b6f9fd7ecd"
    }]
}

可能是以下情况：设备中未收到消息。

1. Android端的发件人ID错误。
2. 服务器端（PHP）的Google API密钥错误。
3. 您要发送到GCM服务器的设备注册ID错误。

请立即验证所有值并检查。 如果一切都完美，那么您必须在设备中收到消息。 请检查设备中的互联网连接。

请使用以下验证您的Menifest.xml文件。

<receiver
            android:name=".GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >

                <!-- Receives the actual messages. -->
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <!-- Receives the registration id. -->
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="your_package" />
            </intent-filter>
        </receiver>

        <service android:name=".GCMIntentService" />
    </application>

    <!-- GCM connects to Internet Services. -->

    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

    <!-- Keeps the processor from sleeping when a message is received. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <!-- Creates a custom permission so only this app can receive its messages. -->
    <permission
        android:name="your_package.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />

    <uses-permission android:name="your_package.permission.C2D_MESSAGE" />

    <!-- This app has permission to register and receive data message. -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

    <!-- Network State Permissions to detect Internet status -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

如果您确实在示例代码中收到消息； 我认为您的项目gcm上不允许服务器的IP地址。 或者您的服务器的防火墙阻止gcm的消息，如https://stackoverflow.com/a/13470029/2917564所示 。 无论哪种方式，我都建议您在服务器上运行仅包含您的注册ID的独立简单php脚本，以确保它不在代码中，您可以找到一个https://stackoverflow.com/a/11253231/ 2917564 。
