android 开启服务进行FTP上传，上传进度在通知栏显示

1.定义广播类，用来接收进度信息，并将信息传递给通知栏中的进度条

package com.screening.uitls;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

import com.application.MyApplication;
import com.screening.activity.AdminSetActivity;
import com.screening.model.Area;
import com.screening.model.Bean;
import com.screening.model.Const;
import com.util.ToastUtils;

import org.litepal.crud.DataSupport;

import java.io.File;
import java.util.List;

public class UpDateBroadcastReceiver extends BroadcastReceiver {
    private static final int notifyId=10;
    @Override
    public void onReceive(Context context, Intent intent) {
        double progress=intent.getDoubleExtra("progress",0);
        Const.getOneItem().getNotificationUtils().updateProgress(notifyId,(int)progress);
        if(progress==100){
//            bt_commit.setEnabled(true);
            ToastUtils.showToast(context,"上传已完成");
            Const.getOneItem().setNotificationUtils(null);
            new Thread(new Runnable() {
                @Override
                public void run() {
                    List areaList= DataSupport.findAll(Area.class);
                    File file=new File(Bean.bePath+areaList.get(0).getCommunity());
                    if(file.exists()){
                        new Deleteutils().deleteLocal(file);
                    }
                }
            }).start();
        }
    }
}

2.使用静态广播（静态广播在程序推出后，后台还在运行时还可以接收到广播信息）

配置文件注册广播：

定义广播权限：

<permission android:name="com.screen.permission.RECEIVER" />

<uses-permission android:name="com.screen.permission.RECEIVER" />

3.定义服务类，在该类中进行上传和广播通知

package com.screening.service;

import android.os.Environment;
import android.os.IBinder;

import com.screening.uitls.LogWriteUtils;
