javamail 使用gmail收发邮件

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 = "[e-mail]"; // 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("[e-mail]", "Johnson");
addressTo = new InternetAddress("[e-mail]", "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(); 
         }
