android - 谷歌云消息，无法初始化接收器

标签 android push-notification google-cloud-messaging

我在这里学习教程:http://developer.android.com/google/gcm/gs.html

我似乎在注册我的 broadcastReceiver 时遇到了一些问题

每当应用程序运行时，在我注册设备并获取注册 ID 之后，我都会收到以下错误

java.lang.RuntimeException: Unable to instantiate receiver com.google.android.gcm.GCMBroadcastReceiver: java.lang.ClassNotFoundException: com.google.android.gcm.GCMBroadcastReceiver

这是完整的堆栈跟踪:

我的 GCMBroadcastReceiver 类

关于为什么我无法注册接收器的任何想法？ 谢谢

最佳答案

该应用正在寻找 com.google.android.gcm.GCMBroadcastReceiver，但您的类在不同的包 pushNotification.GCMBroadcastReceiver 中。

而且您的应用程序包是不同的 - com.myAppName。

虽然您的 GCMBroadcastReceiver 不必与您的应用程序包位于同一包中，但 Intent 过滤器中的类别必须是应用程序包。

你应该改变这个:

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

为此:

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

编辑:

根据您的 list ，您还有其他错误:

您指定了两次广播接收器。如果你想使用你自己的接收器，你应该删除这部分:

    <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:

删除这一行:

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

因为您已经有了这些行(它们是正确的):

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