Не удалось отправить письмо с помощью JavaMail android APi

Question

Я пытаюсь отправить электронное письмо от android с помощью JavaMail Api для Android. Я также включил lesssecure. До сих пор я сделал следующее .. package com.emazdoor.encymail;

public class Mail extends javax.mail.Authenticator { 
    private String _user; 
    private String _pass; 

    private String[] _to; 
    private String _from; 

    private String _port; 
    private String _sport; 

    private String _host; 

    private String _subject; 
    private String _body; 

    private boolean _auth; 

    private boolean _debuggable; 

    private Multipart _multipart; 

    public Mail() { 
     _host = "smtp.gmail.com"; // default smtp server 
     _port = "587";//"465"; // default smtp port 
     _sport = "465"; // default socketfactory port 

     _user = ""; // username 
     _pass = ""; // password 
     _from = ""; // email sent from 
     _subject = ""; // email subject 
     _body = ""; // email body 

     _debuggable = false; // debug mode on or off - default off 
     _auth = true; // smtp authentication - default on 

     _multipart = new MimeMultipart(); 

     // There is something wrong with MailCap, javamail can not find a 
     // handler for the multipart/mixed part, so this bit needs to be added. 
     MailcapCommandMap mc = (MailcapCommandMap) CommandMap 
       .getDefaultCommandMap(); 
     mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); 
     mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); 
     mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); 
     mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); 
     mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); 
     CommandMap.setDefaultCommandMap(mc); 
    } 

    public Mail(String user, String pass) { 
     this(); 

     _user = user; 
     _pass = pass; 
    } 

    public boolean send() throws Exception { 
     Properties props = _setProperties(); 

     if (!_user.equals("") && !_pass.equals("") && _to.length > 0 
       && !_from.equals("") && !_subject.equals("") 
       && !_body.equals("")) { 
//   Session session = Session.getInstance(props, this); 

      Session session = Session.getInstance(props, new javax.mail.Authenticator() { 
       protected PasswordAuthentication getPasswordAuthentication() { 
        return new PasswordAuthentication(_user, _pass); 
       } 
      }); 

      MimeMessage msg = new MimeMessage(session); 

      msg.setFrom(new InternetAddress(_from)); 

      InternetAddress[] addressTo = new InternetAddress[_to.length]; 
      for (int i = 0; i < _to.length; i++) { 
       addressTo[i] = new InternetAddress(_to[i]); 
      } 
      msg.setRecipients(MimeMessage.RecipientType.TO, addressTo); 

      msg.setSubject(_subject); 
      msg.setSentDate(new Date()); 

      // setup message body 
      BodyPart messageBodyPart = new MimeBodyPart(); 
      messageBodyPart.setText(_body); 
      _multipart.addBodyPart(messageBodyPart); 

      // Put parts in message 
      msg.setContent(_multipart); 

      // send email 
      Transport.send(msg); 

      return true; 
     } else { 
      return false; 
     } 
    } 

    public void addAttachment(String filename) throws Exception { 
     BodyPart messageBodyPart = new MimeBodyPart(); 
     DataSource source = new FileDataSource(filename); 
     messageBodyPart.setDataHandler(new DataHandler(source)); 
     messageBodyPart.setFileName(filename); 

     _multipart.addBodyPart(messageBodyPart); 
    } 

    @Override 
    public PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication(_user, _pass); 
    } 

    private Properties _setProperties() { 
     Properties props = new Properties(); 

     props.put("mail.smtp.host", _host); 

     if (_debuggable) { 
      props.put("mail.debug", "true"); 
     } 

     if (_auth) { 
      props.put("mail.smtp.auth", "true"); 
     } 

     props.put("mail.smtp.port", _port); 
     props.put("mail.smtp.socketFactory.port", _sport); 
     props.put("mail.smtp.socketFactory.class", 
       "javax.net.ssl.SSLSocketFactory"); 
     props.put("mail.smtp.socketFactory.fallback", "false"); 

     return props; 
    } 

    // the getters and setters 
    public String getBody() { 
     return _body; 
    } 

    public void setBody(String _body) { 
     this._body = _body; 
    } 

    // more of the getters and setters ….. 
    public void setTo(String[] toArr) { 
     this._to = toArr; 
    } 

    public void setFrom(String string) { 
     this._from = string; 
    } 

    public void setSubject(String string) { 
     this._subject = string; 
    } 
} 

MainActivity

public class MainActivity extends Activity implements OnClickListener { 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final Button send = (Button) this.findViewById(R.id.sendbutton); 
     send.setOnClickListener(this); 
    } 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     final com.emazdoor.encymail.Mail m = new com.emazdoor.encymail.Mail(
       "emailhere@gmail.com", "password"); 
     new AsyncTask<Void, Void, Void>() { 
      @Override 
      public Void doInBackground(Void... voids) { 
       try { 
        String[] toArr = {"grg@gmail.com", 
          "emailhere@gmail.com"}; 
        m.setTo(toArr); 
        m.setFrom("emailhere@gmail.com"); 
        m.setSubject("This is an email sent using my Mail JavaMail wrapper from an Android device."); 
        m.setBody("Email body."); 
        m.send(); 
        Toast.makeText(MainActivity.this, 
         "Email was sent successfully.", 
         Toast.LENGTH_LONG).show(); 
       } catch (Exception e) { 
        Log.e("SendEmail", e.getMessage(), e); 
       } 
       return null; 
      } 
     }.execute(); 

    } 

    } 

Но я продолжал получать эту ошибку

Помощь ценится.

Только что повернутый Lesssecureappaccess дальше сделал трюк. Хотя отправляется только один раз.
