android实现自动发送邮件

本文实例为大家分享了实现了一个android自动发送邮件的demo。支持163，qq邮箱

需要添加activation.jar,additionnal.jar和mail.jar这三个包

首先是一个EmailSender类

import java.io.File;
 
import java.util.Date;
import java.util.Properties;
 
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
 
public class EmailSender {
 private Properties properties;
 private Session session;
 private Message message;
 private MimeMultipart multipart;
 
 public EmailSender() {
 super();
 this.properties = new Properties();
 }
 public void setProperties(String host,String post){
 //地址
 this.properties.put("mail.smtp.host",host);
 //端口号
 this.properties.put("mail.smtp.post",post);
 //是否验证
 this.properties.put("mail.smtp.auth",true);
 this.session=Session.getInstance(properties);
 this.message = new MimeMessage(session);
 this.multipart = new MimeMultipart("mixed");
 }
 
 public void setReceiver(String[] receiver) throws MessagingException{
 Address[] address = new InternetAddress[receiver.length];
 for(int i=0;i

下面是mainactivity代码



import javax.mail.MessagingException;
import javax.mail.internet.AddressException;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
 
public class MainActivity extends Activity {
 
 private Button btnOK; 
  @Override
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btnOK = (Button) findViewById(R.id.button);
    btnOK.setonClickListener(new onClickListener() {
      @Override
      public void onClick(View arg0) {
// sendEmail();
//耗时操作要起线程...有几个新手都是这个问题
 new Thread(new Runnable() {
 
@Override
public void run() {
 try {
 EmailSender sender = new EmailSender();
 //设置服务器地址和端口，网上搜的到
 sender.setProperties("smtp.163.com", "25");
 //分别设置发件人，邮件标题和文本内容
 sender.setMessage("你的163邮箱账号", "EmailSender", "Java Mail ！");
 //设置收件人
 sender.setReceiver(new String[]{"收件人邮箱"});
 //添加附件
 //这个附件的路径是我手机里的啊，要发你得换成你手机里正确的路径
// sender.addAttachment("/sdcard/DCIM/Camera/asd.jpg");
 //发送邮件
 sender.sendEmail("smtp.163.com", "你的163邮箱账号", "你的邮箱密码");//sender.setMessage("你的163邮箱账号", "EmailS//ender", "Java Mail ！");这里面两个邮箱账号要一致
 
 } catch (AddressException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 } catch (MessagingException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
}
}).start();
      }
    });
 
  }
 
}
