It was working normally. Now when I run the program the following error appears:

    Could not connect to SMTP host: smtp.gmail.com, port: 465;

This is my method

public void enviaEmail() {
    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(
                            "[email protected]", "1111111");
                }
            });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[email protected]"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[email protected]"));
        message.setSubject("Novo Cadastro efetuado na Ouvidoria!!!");
        message.setText("Nome do Beneficiário: ," + "" + nome);
        System.out.println("Nome email:"+nome);

        Transport.send(message);

        System.out.println("Done");

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

}

You need to tell him that you are using SSL:

props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

Below a working source code:

String  d_email = "[email protected]",
        d_uname = "Name",
        d_password = "urpassword",
        d_host = "smtp.gmail.com",
        d_port  = "465",
        m_to = "[email protected]",
        m_subject = "Indoors Readable File: " + params[0].getName(),
        m_text = "This message is from Indoor Positioning App. Required file(s) are attached.";
Properties props = new Properties();
props.put("mail.smtp.user", d_email);
props.put("mail.smtp.host", d_host);
props.put("mail.smtp.port", d_port);
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.port", d_port);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

SMTPAuthenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
session.setDebug(true);

MimeMessage msg = new MimeMessage(session);
try {
    msg.setSubject(m_subject);
    msg.setFrom(new InternetAddress(d_email));
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to));

Transport transport = session.getTransport("smtps");
            transport.connect(d_host, Integer.valueOf(d_port), d_uname, d_password);
            transport.sendMessage(msg, msg.getAllRecipients());
            transport.close();

    } catch (AddressException e) {
        e.printStackTrace();
        return false;
    } catch (MessagingException e) {
        e.printStackTrace();
        return false;
    }

Switch:

Transport transport = session.getTransport("smtps");

To:

Transport transport = session.getTransport("smtp");
