我有一个移动应用程序,它注册到c2dm服务器.

我有一台服务器向我的应用程序发送消息,以发送通知.服务器从谷歌c2dm收到ok结果代码.

在LogCat中我看到我的应用程序收到消息但立即产生我在帖子中的错误.而且我创建的通知也被忽略了.

08-10 16:28:09.157: W/GTalkService(13962): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.example.c2dmclient (has extras) }

我不懂.我的清单文件是:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.c2dmclient"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <permission android:name="com.example.c2dmclient.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="com.example.c2dmclient.permission.C2D_MESSAGE" />

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

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
