android自动发送邮件的实现

这两天网上找了点东西，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<receiver.length;i++){
address[i] = new InternetAddress(receiver[i]);
}
this.message.setRecipients(Message.RecipientType.TO, address);
}
/**
* 设置邮件
* @param from 来源
* @param title 标题
* @param content 内容
* @throws AddressException
* @throws MessagingException
*/
public void setMessage(String from,String title,String content) throws AddressException, MessagingException{
this.message.setFrom(new InternetAddress(from));
this.message.setSubject(title);
//纯文本的话用setText()就行，不过有附件就显示不出来内容了
MimeBodyPart textBody = new MimeBodyPart();
textBody.setContent(content,"text/html;charset=gbk");
this.multipart.addBodyPart(textBody);
}
/**
* 添加附件
* @param filePath 文件路径
* @throws MessagingException
*/
public void addAttachment(String filePath) throws MessagingException{
FileDataSource fileDataSource = new FileDataSource(new File(filePath));
DataHandler dataHandler = new DataHandler(fileDataSource);
MimeBodyPart mimeBodyPart = new MimeBodyPart();
mimeBodyPart.setDataHandler(dataHandler);
mimeBodyPart.setFileName(fileDataSource.getName());
this.multipart.addBodyPart(mimeBodyPart);
}
/**
* 发送邮件
* @param host 地址
* @param account 账户名
* @param pwd 密码
* @throws MessagingException
*/
public void sendEmail(String host,String account,String pwd) throws MessagingException{
//发送时间
this.message.setSentDate(new Date());
//发送的内容，文本和附件
this.message.setContent(this.multipart);
this.message.saveChanges();
//创建邮件发送对象，并指定其使用SMTP协议发送邮件
Transport transport=session.getTransport("smtp");
//登录邮箱
transport.connect(host,account,pwd);
//发送邮件
transport.sendMessage(message, message.getAllRecipients());
//关闭连接
transport.close();
}
}

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");//<span style="font-family: Arial, Helvetica, sans-serif;">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</span>

} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}
});

}

}

layout里只有一个简单的button
不贴代码了。

这样就能实现android自动发送邮件了。当应用产生崩溃是，及时记录崩溃信息，发送邮件到你的邮箱，对开发来说是利好的事情
