C2DMBroadcastReceiver的的onReceive没有执行（登记） [英] C2DMBroadcastReceiver's onReceive is not executing (For Registration)

问题描述

林开发C2DM消息应用程序。在我下令使用接收的注册ID IM的 C2DMBroadcastReceiver ， C2DMBaseReceiver 和 C2DMMessaging 类。我将 C2DMReceiver 在我的包，它扩展了 C2DMBaseReceiver 。

Im developing a C2DM Messaging application. In that i order to receive the registration id im using the C2DMBroadcastReceiver, C2DMBaseReceiver and C2DMMessaging class. I will be C2DMReceiver in my package which extends the C2DMBaseReceiver.

}

现在我的问题是，

我调用的注册的C2DMMessaging从我的活动通过传递上下文，该服务将在C2DMMessaging创建的，在那之后我不是接收在 C2DMBroadcastReceiver的的onReceive（）

I calling the Register of the C2DMMessaging from my activity by passing the context, The service is created in the C2DMMessaging, After that im not receiving anything in the C2DMBroadcastReceiver's onReceive().

这是从 vogille.de 中的$ C $词了。这是工作的罚款，如果我用这个本身，而是当我的应用程序使用该即时通讯这个问题来了。

This is the code i got from vogille.de. This is working fine if i use this as such but when im using this in my application this problem is coming.

我已经救援人员到场一些后ñ一派的东西中，我发现问题的可以在清单文件。

I have gone thro' some post n googled something in which i found that the problem may be in manifest file.

我不知道我错了。 能否评价一下这个谁能帮助？

推荐答案

对于模糊的原因，您的接收器类，C2DMReceiver，必须在你的包，它被声明为你的体现你的包名的根。 这是我设法得到这个工作的唯一途径...所以不是：

For an obscure reason, your receiver class, C2DMReceiver, has to be in the root of your package, which is declared as your package name in your manifest. This is the only way i managed to get this working... so instead of :

service android:name="com.sample.gt.c2dm.C2DMReceiver" 

尝试

service android:name=".C2DMReceiver"

这里是我的清单节选（除权限）

here is my manifest excerpt (except the permissions)

 <!--C2DM -->
    <service android:name=".C2DMReceiver" />
    <receiver android:name="com.google.android.c2dm.C2DMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <!-- Receive the actual message -->
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="my.package" />
        </intent-filter>
        <!-- Receive the registration id -->
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="my.package" />
        </intent-filter>
    </receiver>
