email + JS will work as it is pure javascript

http://emailjs.org/

I have also tried to use it, but when using the IMAP or the POP3 client can not be ported to Cordova due to its node dependencies. Also, as an alternative is to use browserify or webpack, but with this components all dependencies are not included when the whole project is built and every dependency inside emailjs project is not discovered, so that options are useless too.

I used the following to send emails:

https://docs.oracle.com/javaee/7/api/javax/mail/package-summary.html

Here's an example:

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class OperacionesCorreo {

public boolean enviarEmail(String para,String asunto,String mensaje){

boolean estado=false;

final String Username="[email protected]";

final String PassWord="your_pass";

Properties properties = System.getProperties();

properties.put("mail.smtp.starttls.enable", "true");

properties.put("mail.smtp.host", "smtp.gmail.com");

properties.put("mail.smtp.user", Username); // User name

properties.put("mail.smtp.password", PassWord); // password

properties.put("mail.smtp.port", "587");

properties.put("mail.smtp.auth", "true");

try{

Session session = Session.getInstance(properties,

new javax.mail.Authenticator() {

@Override

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(Username, PassWord);

}

});

MimeMessage message = new MimeMessage(session);

message.setFrom(new InternetAddress(Username));

message.addRecipient(Message.RecipientType.TO,

new InternetAddress(para));

message.setSubject(asunto);

message.setText(mensaje);

Transport.send(message);

//Message sent

estado=true;

}catch (MessagingException mex) {

mex.printStackTrace();

estado=false;

}

return estado;

}

}

Thank you. That's useful only for Android or other OS Java based. That's why I am looking for something in higher layer.
