Android Question Send html email that include pictures

[le_toubib]

Hello there my friends
I do enjoy learning from this forum everyday.

I know how to send an html email, but How to send an html email that contains a local image (1.5mb) within the body ..
Thx

This question was discussed in the past without a reliable / working solution.

A simple solution is to send the image as an attachment.

Hi erel
Thanks for replying
I just found this code on stack
That supposedly works fine.
Could that help?
Is it possible to convert it to b4a?

   you have need three lib  of java mail 

    1.activation.jar
    2.additionnal.jar
    3.mail.jar




    public class AutomaticEmailActivity extends Activity {

        @Override 
        public void onCreate(Bundle savedInstanceState) { 
            super.onCreate(savedInstanceState); 
            setContentView(R.layout.main); 
            if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }



            final String fromEmail = "[email protected]"; //requires valid gmail id
            final String password = "abc"; // correct password for gmail id
            final String toEmail = "[email protected]"; // can be any email id 

            System.out.println("SSLEmail Start");
            Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.gmail.com"); //SMTP Host
            props.put("mail.smtp.socketFactory.port", "465"); //SSL Port
            props.put("mail.smtp.socketFactory.class",
                    "javax.net.ssl.SSLSocketFactory"); //SSL Factory Class
            props.put("mail.smtp.auth", "true"); //Enabling SMTP Authentication
            props.put("mail.smtp.port", "465"); //SMTP Port

            Authenticator auth = new Authenticator() {
                //override the getPasswordAuthentication method
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(fromEmail, password);
                }
            };

            final Session session = Session.getDefaultInstance(props, auth);
            Button send_email=(Button) findViewById(R.id.send_email);
            send_email.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {

                    sendImageEmail(session, toEmail,"SSLEmail Testing Subject with Image", "SSLEmail Testing Body with Image");

                }
            });

        }




        public static void sendImageEmail(Session session, String toEmail, String subject, String body){
            try{
                MimeMessage msg = new MimeMessage(session);
                msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
                msg.addHeader("format", "flowed");
                msg.addHeader("Content-Transfer-Encoding", "8bit");

                msg.setFrom(new InternetAddress("[email protected]", "NoReply-JD"));

                msg.setReplyTo(InternetAddress.parse("[email protected]", false));

                msg.setSubject(subject, "UTF-8");

                msg.setSentDate(new Date());

                msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail, false));

                MimeMultipart multipart = new MimeMultipart("related");

                BodyPart messageBodyPart = new MimeBodyPart();
                String htmlText = "<H1>Hello</H1><img src=\"cid:image\">";
                messageBodyPart.setContent(htmlText, "text/html");
                // add it
                multipart.addBodyPart(messageBodyPart);


                String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
                String filename = base + "/photo.jpg";

                messageBodyPart = new MimeBodyPart();
                DataSource fds = new FileDataSource(filename);

                messageBodyPart.setDataHandler(new DataHandler(fds));
                messageBodyPart.setHeader("Content-ID", "<image>");
                multipart.addBodyPart(messageBodyPart);  
                msg.setContent(multipart);


                // Send message
                Transport.send(msg);
                System.out.println("EMail Sent Successfully with image!!");
            }catch (MessagingException e) {
                e.printStackTrace();
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
        }
    }

I wouldn't use this code in an application as it sends the message on the main thread.

Check NetExtra library. I think that it allows you set the headers which is the part missing in SMTP object from the Net library.
