3.使用工具包：

  but_emailtest.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//使用HandlerThreadmhandlerthread=new HandlerThread("myhandlerthread");mhandlerthread.start();mhandler = new Handler(mhandlerthread.getLooper());mhandler.post(mRunnable);}});}Runnable mRunnable = new Runnable() {@Overridepublic 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="fajianren@17xu.com";String host = "smtp.17xu.com";String address = "88888@17xu.com"; //发件人地址String from = "88888@17xu.com";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();}}
