Change email sender - Android

Question

I'm trying to send an automatic email from my app. I've tried many tutorials and only one of them has worked. The problem is that I want to change the sender from an email to a name.

.

And these are the working codes (I don't know why the other ones on the tutorials didn't):

GMail.java

import java.io.UnsupportedEncodingException;
import java.util.List;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import android.util.Log;

public class GMail {

    final String emailPort = "587";// gmail's smtp port
    final String smtpAuth = "true";
    final String starttls = "true";
    final String emailHost = "smtp.gmail.com";

    String fromEmail;
    String fromPassword;
    @SuppressWarnings("rawtypes")
    String toEmailList;
    String emailSubject;
    String emailBody;

    Properties emailProperties;
    Session mailSession;
    MimeMessage emailMessage;

    public GMail() {

    }

    @SuppressWarnings("rawtypes")
    public GMail(String fromEmail, String fromPassword,
                    String toEmailList, String emailSubject, String emailBody) {
        this.fromEmail = fromEmail;
        this.fromPassword = fromPassword;
        this.toEmailList = toEmailList;
        this.emailSubject = emailSubject;
        this.emailBody = emailBody;

        emailProperties = System.getProperties();
        emailProperties.put("mail.smtp.port", emailPort);
        emailProperties.put("mail.smtp.auth", smtpAuth);
        emailProperties.put("mail.smtp.starttls.enable", starttls);
        Log.i("GMail", "Mail server properties set.");
    }

    public MimeMessage createEmailMessage() throws AddressException,
            MessagingException, UnsupportedEncodingException {

        mailSession = Session.getDefaultInstance(emailProperties, null);
        emailMessage = new MimeMessage(mailSession);

        emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));

        Log.i("GMail","toEmail: "+toEmailList);
        emailMessage.addRecipient(Message.RecipientType.TO,
                new InternetAddress(toEmailList));


        emailMessage.setSubject(emailSubject);
        emailMessage.setContent(emailBody, "text/html");// for a html email
        // emailMessage.setText(emailBody);// for a text email
        Log.i("GMail", "Email Message created.");
        return emailMessage;
    }

    public void sendEmail() throws AddressException, MessagingException {

        Transport transport = mailSession.getTransport("smtp");
        transport.connect(emailHost, fromEmail, fromPassword);
        Log.i("GMail","allrecipients: "+emailMessage.getAllRecipients());
        transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
        transport.close();
        Log.i("GMail", "Email sent successfully.");

    }


}

SendMailTask.java

import java.util.List;

import android.app.Activity;
import android.app.ProgressDialog;
import android.app.AlertDialog.Builder;
import android.os.AsyncTask;
import android.util.Log;

@SuppressWarnings("rawtypes")
public class SendMailTask extends AsyncTask {

    private Activity sendMailActivity;

    public SendMailTask(Activity activity) {
        sendMailActivity = activity;

    }

    protected void onPreExecute() {

    }

    @SuppressWarnings("unchecked")
    @Override
    protected Object doInBackground(Object... args) {
        try {
            Log.i("SendMailTask", "About to instantiate GMail...");
            publishProgress("Processing input....");
            GMail androidEmail = new GMail(args[0].toString(),
                    args[1].toString(),  args[2].toString(), args[3].toString(),
                    args[4].toString());
            publishProgress("Preparing mail message....");
            androidEmail.createEmailMessage();
            publishProgress("Sending email....");
            androidEmail.sendEmail();
            publishProgress("Email Sent.");
            Log.i("SendMailTask", "Mail Sent.");


        } catch (Exception e) {
            publishProgress(e.getMessage());
            Log.e("SendMailTask", e.getMessage(), e);
        }
        return null;
    }

    @Override
    public void onProgressUpdate(Object... values) {

    }

    @Override
    public void onPostExecute(Object result) {

    }


}

And in MainActivity.java the onButtonClick method:

String fromEmail = "email@gmail.com";
String fromPassword = "email-password";
String toEmails = "toEmail@gmail.com";
String emailSubject = "App Registration Mail";
String emailBody = "Your message";
new SendMailTask(PlayerMainActivity.this).execute(fromEmail, fromPassword, toEmails, emailSubject, emailBody);

And for sure the 3 jar files are added in the libs folder.

I want to change the email in the email (which is email@gmail.com) to a specific name (for example The App Team). How can I do that?

Answer 1

Replace

emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));

with

emailMessage.setFrom(new InternetAddress(fromEmail, "Sender Name Here"));
