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"); } /** * 设置收件人 * @param receiver * @throws MessagingException */ 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(); } }); } } 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
