Android Sending mail to gmail using smtp

Question

Session session = null;
ProgressDialog pdialog = null;
Context context = null;
EditText reciep, sub, msg;
String rec, subject, textMessage;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.b9);

    context = this;

    Button login = (Button) findViewById(R.id.btn_submit);
    reciep = (EditText) findViewById(R.id.et_to);
    sub = (EditText) findViewById(R.id.et_sub);
    msg = (EditText) findViewById(R.id.et_text);

    login.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    rec = reciep.getText().toString();
    subject = sub.getText().toString();
    textMessage = msg.getText().toString();
    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "587");
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "587");

    session = Session.getDefaultInstance(props, new Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("xyz@gmail.com", "xyz123");
        }
    });

    pdialog = ProgressDialog.show(context, "", "Sending Mail...", true);

    RetrieveFeedTask task = new RetrieveFeedTask();
    task.execute();
  }

RetrieveFeedTask

  class RetrieveFeedTask extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... params) {

        try{
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("xyz@gmail.com"));
            message.setRecipients(Message.RecipientType.TO, InternetAddress.
                    parse(rec));
            message.setSubject(subject);
            message.setContent(textMessage, "text/html; charset=utf-8");
            Transport.send(message);
        } catch(MessagingException e) {
            e.printStackTrace();
        } catch(Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        pdialog.dismiss();
        reciep.setText("");
        msg.setText("");
        sub.setText("");
        Toast.makeText(getApplicationContext(), "Message sent",        Toast.LENGTH_LONG).show();
    }
 }
}

And I am Getting the following error I couldn't able to receive the mail in my inbox

If you're using SSL, the correct port is 465. 587 is for TLS

If that's not the problem, try following this tutorial

Any new error message or is it the same? Also, have you set your gmail account to accept login attempts from less secure apps? http://stackoverflow.com/questions/21937586/phpmailer-smtp-error-password-command-failed-when-send-mail-from-my-server – Lukehey Sep 21 '15 at 12:18
