MyAuthenticator 类

package com.example.mailtestdemo;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

public class MyAuthenticator extends Authenticator{
String userName = null;
String password = null;

public MyAuthenticator(){}

public MyAuthenticator(String userName,String password){
this.userName = userName;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication(userName,password);
}
}

MainActivity 类，使用上面3个类，实现发邮件

package com.example.mailtestdemo;

import com.example.mailtestdemo.MultiMailsender.MultiMailSenderInfo;

import android.os.Bundle;
import android.os.StrictMode;
import android.annotation.SuppressLint;
import android.app.Activity;

public class MainActivity extends Activity {

@SuppressLint({ "NewApi", "NewApi" })
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);

// 这个类主要是设置邮件
MultiMailSenderInfo mailInfo = new MultiMailSenderInfo();
mailInfo.setMailServerHost("smtp.163.com"); // smtp.qq.com,smtp.sohu.com,smtp.163.com
mailInfo.setMailServerPort("25"); // smtp 端口：25
mailInfo.setValidate(true);
mailInfo.setUserName("xxxxx@163.com");
mailInfo.setPassword("xxxx");// 您的邮箱密码
mailInfo.setFromAddress("xxx@163.com");
mailInfo.setToAddress("sproutting@sohu.com");
// mailInfo.setToAddress("xxx@sina.cn");
// mailInfo.setToAddress("xxx@qq.com");
// mailInfo.setToAddress("xxx@126.com");

mailInfo.setSubject("设置邮箱标题");
mailInfo.setContent("设置邮箱内容");
String[] receivers = new String[]{"281406222@qq.com"};
String[] ccs = receivers;
mailInfo.setReceivers(receivers);
mailInfo.setCcs(ccs);

// 这个类主要来发送邮件
MultiMailsender sms = new MultiMailsender();
sms.sendTextMail(mailInfo);// 发送文体格式
MultiMailsender.sendHtmlMail(mailInfo);//发送html格式
MultiMailsender.sendMailtoMultiCC(mailInfo);//发送抄送
}

}
}
这个项目需要导入activation.jar，additionnal.jar，mail.jar，把这三个jar复制到项目下的libs文件夹下
