        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

}

3.使用工具包：

  but_emailtest.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //使用HandlerThread
                mhandlerthread=new HandlerThread("myhandlerthread");
                mhandlerthread.start();
                 mhandler = new Handler(mhandlerthread.getLooper());
                mhandler.post(mRunnable);

            }
        });

    }
    Runnable mRunnable = new Runnable() {

        @Override
        public void run() {
            NetworkUtils nu=new NetworkUtils();
            EmailUtils email=new EmailUtils();
            //emsuper.run();ail.sendToFileEmail("哈哈哈test","这是荣哦支持你下哈哈",MinShiLi.this);
            String to="[email protected]";
            String host = "smtp.17xu.com";
            String address = "[email protected]"; //发件人地址
            String from = "[email protected]";
            String password = "******";// 密码
            String filepath=nu.getSDPath()+"/"+"qq.png";
            String port = "25"; //发邮件端口号
            try {
                //email.SendEmail(host, address, from, password, to, port, "主题测试", "内容哦哈哈哈哈哈哈哈");
//附件
                email.SendEmailfile(host, address, from, password, to, port, "主题测试", "内容哦哈哈哈哈哈哈哈",filepath);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };

4.sd卡获取文件路径、判断网络是否链接

package com.kllayhello.utils;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Environment;

import java.io.File;

/**
 * Created by Administrator on 2016/6/30.
 */
public class NetworkUtils {
    /**
     * 判断网络是否链接
     * */
    public boolean isNetworkConnected(Context context) {
        if (context != null) {
            ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();
            if (mNetworkInfo != null) {
                return mNetworkInfo.isAvailable();
            }
        }
        return false;
    }

/**
 * 判断sd卡是否存在 并获取路径
 * */
public String getSDPath(){
        File sdDir = null;
        boolean sdCardExist = Environment.getExternalStorageState()
                .equals(android.os.Environment.MEDIA_MOUNTED);//判断sd卡是否存在
        if(sdCardExist)
        {
            sdDir = Environment.getExternalStorageDirectory();//获取跟目录
        }
        return sdDir.toString();
    }

}
