关于javamail在android SDK中使用，网上已经有很多资料，这里不再赘述。

以下文章说下javamail在收发gmail邮箱进行收发邮件的一些设置

1.发送邮件

密码验证

class PopupAuthenticator extends Authenticator {public PasswordAuthentication getPasswordAuthentication() {String username = "zhouxufeng2012@gmail.com"; // 邮箱登录帐号String pwd = "XXXXXX"; // 登录密码return new PasswordAuthentication(username, pwd);}}

参数设置

  props.setProperty("mail.smtp.host", "smtp.gmail.com");  props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");  props.setProperty("mail.smtp.socketFactory.fallback", "false");  props.setProperty("mail.smtp.port", "465");  props.setProperty("mail.smtp.socketFactory.port", "465");  props.setProperty("mail.smtp.auth", "true");  props.setProperty("mail.smtp.ssl",  "true");  props.setProperty("mail.smtp.starttls.enable","true");PopupAuthenticator auth = new PopupAuthenticator();Session session = Session.getInstance(props, auth);MimeMessage message = new MimeMessage(session);           Address addressFrom;Address addressTo;Address addressCopy;addressFrom = new InternetAddress("zhouxufeng2012@gmail.com", "Johnson");addressTo = new InternetAddress("zhouxufeng2012@gmail.com", "gZhou");message.setText("中文测试");message.setSubject("H--H");message.setFrom(addressFrom);message.addRecipient(Message.RecipientType.TO,addressTo);message.addRecipient(Message.RecipientType.CC,addressCopy);message.saveChanges();Transport.send(message);


2.接收邮件
                    gmail接收邮件有两种方式，pop3方式和imap方式，pop3的我没有试过，贴下imap接收的代码

        Properties props = new Properties();        props.setProperty("mail.imap.host", "imap.gmail.com");        props.put("mail.store.protocol", "imap");          props.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");        props.setProperty("mail.imap.socketFactory.fallback", "false");        //props.put("mail.imap.connectiontimeout", ConfigKeys.IMAP_CONNECTIONTIMEOUT);                props.setProperty("mail.imap.port", "993");        props.setProperty("mail.imap.socketFactory.port", "993");                PopupAuthenticator auth = new PopupAuthenticator();        Session session = Session.getInstance(props,auth);        session.setDebug(true);                        Store store;int count;store = session.getStore();store.connect();        Folder folder = store.getFolder("INBOX");        folder.open(Folder.READ_WRITE);        Message msgs[] = folder.getMessages();        count = msgs.length;        System.out.println("Message Count:"+count);        ReciveMail rm = null;        for(int i=0;i<count;i++){            rm = new ReciveMail((MimeMessage) msgs[i]);            rm.recive(msgs[i],i);            System.out.println("Message:"+rm.getBodyText());        }         folder.close(true);        store.close();

3. 邮件删除
imap方式比pop3多的功能就是对邮箱的一些操作
在网上看到的一些大侠们说需要添加这么两句，就能实现接收后立即删除

   msgs[i].setFlag(Flags.Flag.DELETED, true);               msgs[i].saveChanges();

但我试了下，仅上面一句就可以了，加上第二句反而会报错，如下

         for(int i=0;i<count;i++){             rm = new ReciveMail((MimeMessage) msgs[i]);             rm.recive(msgs[i],i);                         msgs[i].setFlag(Flags.Flag.DELETED, true);              //msgs[i].saveChanges();          }
