Question

我遵循这里的教程：http://developer.android.com/google/gcm/gs.html

我似乎在注册broadcastReceiver

时遇到了一些问题

每当应用程序运行时，我注册设备后立即收到以下错误，并获得注册ID

java.lang.RuntimeException：无法实例化接收器 com.google.android.gcm.GCMBroadcastReceiver：抛出java.lang.ClassNotFoundException： com.google.android.gcm.GCMBroadcastReceiver

这是完整的stackTrace：

关于为什么我无法注册接收器的任何想法？感谢

Answer 1

该应用正在寻找com.google.android.gcm.GCMBroadcastReceiver，但您的课程位于另一个包pushNotification.GCMBroadcastReceiver。

您的应用包是另一个 - com.myAppName。

虽然您的GCMBroadcastReceiver不必与应用包在同一个包中，但意图过滤器中的类别必须是应用的包。

你应该改变这个：

        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="pushNotification" />
        </intent-filter>

对此：

        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.myAppName" />
        </intent-filter>

编辑：

根据您的清单，您还有其他错误：

您指定两次广播接收器。如果您想使用自己的Receiver，则应删除此部分：

    <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.gotoohlala" />
        </intent-filter>
    </receiver>

另一个问题：

删除此行：

<uses-permission android:name="com.gotoohlala.gcm.permission.C2D_MESSAGE" />

由于您已经拥有这些行（正确）：

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

Answer 2

尝试检查v4库。 属性 - ＆gt; Java构建路径 - ＆gt;订单和导出

谷歌云消息传递，无法初始化接收器
