can't instantiate class com.example.xxx.xx.MainActivity$MyReceiver不能初始化内部类

问题困扰我很久了,从国内国外网站均没有找到有效的解决办法,不知道大神们都怎么解决的,特来问一下,希望不吝赐教.
先说一下我要实现的功能:就是获取从bmob的服务器推送过来的消息,用BroadcastReceiver接收,接收到之后再发送一个广播给主界面的broadcastReceiver接收,获取到推送过来的数据之后显示到textView上.就这么简单,但是运行的时候老是报不能初始化类的异常,从各种渠道查找解决办法也没找到,不知道该怎么解决,请这里的大神给个有效的建议或者说,有更好的方式实现这个功能,下面是我的代码:

package com.example.administrator.bmob;



import android.app.Notification;

import android.app.NotificationManager;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.util.Log;



import cn.bmob.push.PushConstants;



public class Receiver extends BroadcastReceiver {

    private NotificationManager manager;

    private String STATIC_NORMAL_ACTION = "com.example.administrator.bmob.TEST";



    @Override

    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(PushConstants.ACTION_MESSAGE)) {

            Log.d("bmob", "客户端收到推送内容：" + intent.getStringExtra(PushConstants.EXTRA_PUSH_MESSAGE_STRING));

            String msg = intent.getStringExtra(PushConstants.EXTRA_PUSH_MESSAGE_STRING);



            manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

            Notification.Builder builder = new Notification.Builder(context);

            builder.setContentText(msg)

                    .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)

                    .setTicker("懒人账本提醒...")

                    .setAutoCancel(true)

                    .setSmallIcon(R.mipmap.ic_launcher);

            Notification notification = builder.build();

            manager.notify(1, notification);

            Intent data = new Intent(STATIC_NORMAL_ACTION);

            Bundle bundle = new Bundle();

            bundle.putString("data", msg);

            data.putExtras(bundle);

            context.sendOrderedBroadcast(data, null);

        }

    }

}

主界面代码:

package com.example.administrator.bmob;



import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.widget.TextView;



import cn.bmob.push.BmobPush;

import cn.bmob.v3.Bmob;

import cn.bmob.v3.BmobInstallation;



public class MainActivity extends AppCompatActivity {

    private TextView textView;

    private String STATIC_NORMAL_ACTION = "com.example.administrator.bmob.TEST";

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        textView = (TextView) findViewById(R.id.textView);

        // 初始化BmobSDK

        Bmob.initialize(this, "336be8699869f10b984f71c0c3cdb91a");

        // 使用推送服务时的初始化操作

        BmobInstallation.getCurrentInstallation(this).save();

        // 启动推送服务

        BmobPush.startWork(this, "336be8699869f10b984f71c0c3cdb91a");



       /* IntentFilter filter = new IntentFilter(STATIC_NORMAL_ACTION);

        MyReceiver receiver = new MyReceiver();

        registerReceiver(receiver, filter);*/

    }

    public class MyReceiver extends BroadcastReceiver {

        @Override

        public void onReceive(Context context, Intent intent) {

            if (intent.getAction().equals(STATIC_NORMAL_ACTION)) {

                Bundle bundle = getResultExtras(true);

                String data = bundle.getString("data");

                textView.setText(data);

            }

        }

    }

}

这是报出来的异常:

 Caused by: java.lang.InstantiationException: can't instantiate class com.example.administrator.bmob.MainActivity$MyReceiver; no empty constructor
