编码实现gmail中的附件

android问题：

我的代码已经实现了用gmail发送邮件，现在我需要发送的邮件可以添加附件，没有用户交互。谁能帮忙告诉一下怎么实现啊？

解决方案

直接把代码给你吧

public synchronized void sendMail(String subject String body String sender String recipients File attachment) throws Exception {    try{    MimeMessage message = new MimeMessage(session);    message.setSender(new InternetAddress(sender));    message.setSubject(subject);    MimeBodyPart mbp1 = new MimeBodyPart();    mbp1.setText(body);    MimeBodyPart mbp2 = new MimeBodyPart();    FileDataSource fds = new FileDataSource(attachment);    mbp2.setDataHandler(new DataHandler(fds));    mbp2.setFileName(fds.getName());    Multipart mp = new MimeMultipart();    mp.addBodyPart(mbp1);    mp.addBodyPart(mbp2);    message.setContent(mp);    if (recipients.indexOf('') > 0)        message.setRecipients(Message.RecipientType.TO InternetAddress.parse(recipients));    else        message.setRecipient(Message.RecipientType.TO new InternetAddress(recipients));    Transport.send(message);    }catch(Exception e){    }}
