试试这个...

 属性道具=新特性（）;
    // IMAPS协议
    props.setProperty（mail.store.protocol，IMAPS）;
    //设置主机地址
    props.setProperty（mail.imaps.host，imaps.gmail.com）;

    props.setProperty（mail.imaps.socketFactory.fallback，假）;
    //设置IMAP会话
    会议imapSession = Session.getInstance（道具）;

店中店= imapSession.getStore（IMAPS）;
//通过发送用户名和密码连接到服务器。
//例邮件服务器= imap.gmail.com，用户名= ABC，密码= ABC
store.connect（邮件服务器，account.username，account.password）;
//获取收件箱中Forlder所有邮件
收件箱= store.getFolder（收件箱）;
inbox.open（Folder.READ_ONLY）;

消息[]结果= inbox.getMessages（）;
 

I want to get all inbox mails of different mail services like gmail, hotmail, rediffmail etc. into my application. Initially I tried to get gmail mails using Imap. But I am getting a socket exception. Here is the code I tried. Please help me.

public void getMails(View V){
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
props.setProperty("mail.imap.port", "993");

props.setProperty("mail.imap.socketFactory.class", .ssl.SSLSocketFactory");
props.setProperty("mail.imap.socketFactory.fallback", "false");
    try {
      Session session = Session.getDefaultInstance(props, null);
      Store store = session.getStore("imaps");
      store.connect("imap.gmail.com", "aravelliramesh35@gmail.com", "pswd");
    }
  //}catch (NoSuchProviderException e) {
  //   e.printStackTrace();
  //   System.exit(1);
  //} 
    catch (MessagingException e) {
        e.printStackTrace();
        System.exit(2);
    }
}

Try this...

 Properties props = new Properties();
    //IMAPS protocol
    props.setProperty("mail.store.protocol", "imaps");
    //Set host address
    props.setProperty("mail.imaps.host", imaps.gmail.com);
    //Set specified port
    props.setProperty("mail.imaps.port", "993″);
    //Using SSL
    props.setProperty("mail.imaps.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.setProperty("mail.imaps.socketFactory.fallback", "false");
    //Setting IMAP session
    Session imapSession = Session.getInstance(props);

Store store = imapSession.getStore("imaps");
//Connect to server by sending username and password.
//Example mailServer = imap.gmail.com, username = abc, password = abc
store.connect(mailServer, account.username, account.password);
//Get all mails in Inbox Forlder
inbox = store.getFolder("Inbox");
inbox.open(Folder.READ_ONLY);
//Return result to array of message
Message[] result = inbox.getMessages();
