我尝试使用GCM服务创建测试应用程序,遵循Google手册 https://developer.android.com/google/gcm/client.html#app
但是当我接收消息时,出现了以下错误:
无法实例化接收器 com.example.testpushnotification.GcmBroadcastReceiver: java.lang.ClassNotFoundException: 在路径上找不到类 "com.example.testpushnotification.GcmBroadcastReceiver": DexPathList[[zip file "/data/app/com.example.testpushnotification-2.apk"], nativeLibraryDirectories=[/data/app-lib/com.example.testpushnotification-2, /vendor/lib, /system/lib]]
我查看了所有相关问题,但它们没有解决方案或解决方案没有帮助或者它们已被弃用。
我的清单文件:

以下是位于com.example.testpushnotification包中的GcmBroadcastReceiver源代码:
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路径中包含的包与我的不同?
请问,如何修复它?
已修复 将 <receiver
android:name=".GcmBroadcastReceiver"
..
</receiver>
改为 <receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
..
</receiver>
