java.lang.RuntimeException:无法实例化服务com.google.android.gcm.GCMBroadCastReceiver [英] java.lang.RuntimeException: Unable to instantiate service com.google.android.gcm.GCMBroadCastReceiver

问题描述

我正在开发一个android应用程序.

I am developing an android App.

我正在通过GCM实施推送通知.

I am implementing push notification with GCM.

但是，我无法从服务器接收推送通知.错误日志如下.

However, I cannot receive push notification from my server. The error log says below.

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在下面.

</manifest>

GcmBroadcastReceiver.java在下面.

GcmBroadcastReceiver.java is below.

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);
    }

}

我确认我已正确导入android-support-v4.jar和google-play-services.jar. 我尝试了Google搜索提供的一些解决方案，但是还无法解决.

I confirm that I properly import android-support-v4.jar and google-play-services.jar. I tried some solutions from Google Search, however, I cannot solve yet.

您能告诉我如何解决上述问题吗?

Could you tell me how to solve the above problem?

推荐答案

在清单中，您写道:

android:name="com.google.android.gcm.GCMBroadcastReceiver"

但是您的GcmBroadcastReceiver.java在软件包net.myapp

将android:name="com.google.android.gcm.GCMBroadcastReceiver"更改为android:name="net.myapp.GcmBroadcastReceiver"
