谷歌云消息传递,无法初始化接收器

Question

我按照这里的教程:http://developer.android.com/google/gcm/gs.html

我似乎有一些注册我的broadcastReceiver的问题

每当应用程序运行时,我在注册设备后获得以下错误,并获得注册ID

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

这是完整的stackTrace:

关于为什么我不能注册接收器的任何想法？谢谢

Answer 1

该应用程序正在寻找com.google.android.gcm.GCMBroadcastReceiver,但你的课程是在一个不同的包pushNotification.GCMBroadcastReceiver.

你的应用程序包是一个不同的 - com.myAppName.

虽然您GCMBroadcastReceiver不必与应用程序包位于同一个程序包中,但intent过滤器中的类别必须是应用程序的程序包.

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" />

既然你已经拥有这些行(这是正确的):

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