Email-SMTP in Android | BackgroundMail

Here in this Android tutorial, we will reuse that same code which used to send email using GMail from Java.

Call Method:

GMailSender sender = new GMailSender("email", "psw");

       

String strBody = "Name:- "+name.getText().toString()+"\nEmail Address:-"+Fromemail.getText().toString()+"\nSubject:-+sub.getText().toString()+"\nMessage:-"+body.getText().toString();

sender.sendMail(sub.getText().toString(),strBody,Fromemail.getText().toString(),"toemail");

public class GMailSender extends javax.mail.Authenticator

{

    private String mailhost = "smtp.gmail.com";

    private String user;

    private String password;

    private Session session;

    static

    {

   //Security.addProvider(new com.efp.harmony.xnet.provider.jsse.JSSEProvider());

    }

    public GMailSender(String user, String password)

    {

        this.user = user;

        this.password = password;

        Properties props = new Properties();

        props.setProperty("mail.transport.protocol", "smtp");

        props.setProperty("mail.host", mailhost);

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

        props.put("mail.smtp.port", "465");

        props.put("mail.smtp.socketFactory.port", "465");

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

        props.put("mail.smtp.socketFactory.fallback", "false");

        props.setProperty("mail.smtp.quitwait", "false");

        session = Session.getDefaultInstance(props, this);

    }

    protected PasswordAuthentication getPasswordAuthentication()

    {

        return new PasswordAuthentication(user, password);

    }

    public synchronized void sendMail(String subject, String body, String fromEmail, String ToEmail) throws Exception {

        try

        {        

         MimeMessage message = new MimeMessage(session);

          DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));         

         message.setSender(new InternetAddress(fromEmail));    

      

         message.setSubject(subject);

         message.setDataHandler(handler);

         if (ToEmail.indexOf(',') > 0)

             message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(ToEmail));

         else

             message.setRecipient(Message.RecipientType.TO, new InternetAddress(ToEmail));

         Transport.send(message);

        }

        catch(Exception e)

        {

        }

    }

    public class ByteArrayDataSource implements DataSource

    {

        private byte[] data;

        private String type;

        public ByteArrayDataSource(byte[] data, String type)

        {

            super();

            this.data = data;

            this.type = type;

        }

        public ByteArrayDataSource(byte[] data)

        {

            super();

            this.data = data;

        }

        public void setType(String type)

        {

            this.type = type;

        }

        public String getContentType()

        {

            if (type == null)

                return "application/octet-stream";

            else

                return type;

        }

        public InputStream getInputStream() throws IOException

        {

            return new ByteArrayInputStream(data);

        }

        public String getName()

        {

            return "ByteArrayDataSource";

        }

        public OutputStream getOutputStream() throws IOException {

        

            throw new IOException("Not Supported");

        }

    }

}
