android - 无法实例化 GcmBroadcastReceiver

Question

根据 Google 手册 https://developer.android.com/google/gcm/client.html#app，我尝试使用 GCM 服务创建测试应用程序

但是当我收到消息时 - 我有这个错误:

Unable to instantiate receiver com.example.testpushnotification.GcmBroadcastReceiver: java.lang.ClassNotFoundException: Didn't find class "com.example.testpushnotification.GcmBroadcastReceiver" on path: DexPathList[[zip file "/data/app/com.example.testpushnotification-2.apk"], nativeLibraryDirectories=[/data/app-lib/com.example.testpushnotification-2, /vendor/lib, /system/lib]]

我一直在寻找所有相同的问题，但他们没有解决方案或解决方案没有帮助或已被弃用。

我的 list :

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

            <category android:name="com.example.testpushnotification"/>
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService"/>
</application>

以及com.example.testpushnotification包中GcmBroadcastReceiver的源码:

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }

为什么 Dex 路径包含的包与我的不同？

请问如何解决？

已修复已更改 <receiver
android:name=".GcmBroadcastReceiver"
..
</receiver>

到<receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
..
</receiver> (区分大小写)

试试这个:

转到 Project/Properties/Java Build Path/Order and Export -- 确保在 Android Dependencies 和支持库前面有一个检查，如果你使用它。标记所有复选框。单击 Apply 并清理项目。

像这样添加:

   <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.test.android" />
        </intent-filter>
    </receiver>

它应该是:com.google.android.gcm.GCMBroadcastReceiver 而不是 .GCMBroadcastReceiver

这对我有用。希望对您有所帮助。
