我正在开发一款Android应用程序。
我正在使用GCM实现推送通知。
然而,我无法从服务器接收推送通知。错误日志显示如下。
java.lang.RuntimeException: Unable to instantiate service
com.google.android.gcm.GCMBroadCastReceiver: java.lang.ClassNotFoundException:
Didn't find class "com.google.android.gcm.GCMBroadCastReceiver" on path: DexPathList
AndroidManifest.xml 如下。

GcmBroadcastReceiver.java如下。
package net.myapp;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
我确认已经正确导入了android-support-v4.jar和google-play-services.jar。我尝试了一些谷歌搜索的解决方案,但是还没有解决。
请问您能告诉我如何解决上述问题吗?
gcm.jar
