  setContentView(R.layout.activity_main);

  Button login = (Button) findViewById(R.id.mBtnSubmit);
  login.setOnClickListener(new View.OnClickListener() {

  public void onClick(View arg0) {
  Properties props = new Properties();
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.socketFactory.port", "465");
  props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.port", "465");

  Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
  return new PasswordAuthentication("dipakkeshariya@android.com", "dipakkeshariya");
  }
  });

  try {
  Message message = new MimeMessage(session);
  message.setFrom(new InternetAddress("dipak.keshariya@android.com"));
  message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("dipak.keshariya@mobileappdeveloper.com"));
message.setSubject("Testing Subject");
  message.setContent("Hi Dipak Keshariya (Android Developer)", "text/html; charset=utf-8");

  Transport.send(message);

  } catch (MessagingException e) {
  throw new RuntimeException(e);
  }
            }
