I used this tutorial to send emails from inside my app. I used the same code to 3 different apps and it all worked well. But now, a few months later, it stopped working. I have searched all the possible sites, but none of them helped me. I tried setting a lower security from my Gmail account and also changing the properties for my session, but nothing worked. I would really appreciate some help.
Log.d("EmailSender","sending message");
Properties props = new Properties();
props.put("mail.smtp.host", host);
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(user,pass);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(user));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(SharedPreferenceUtils.getUserEmail(getActivity())));
message.setSubject(subject);
message.setContent(content, "text/html; charset=utf-8");
//Transport.send(message);
Transport transport = session.getTransport("smtps");
transport.connect (host, Integer.parseInt(port), user, pass);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
Log.d("EmailSender", "message sent");
} catch (MessagingException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
My error:

From the logs:
java.net.ConnectException: failed to connect to smtp.gmail.com/2a00:1450:4013:c01::6d (port 465) after 90000ms: isConnected failed: ENETUNREACH (Network is unreachable)
Network is unreachable. The code looks okay, therefore the issue must be with the network. Please check your connectivity. Possible causes could be:
For future, you can add a network-check before sending network requests. This thread has some good answers for checking the network connectivity: How to check internet access on Android? InetAddress never times out
