Send email through App without opening mail App in Android

so I searched a lot to send an email throught my app, but without the user having to log in in an email app and send it himself. I would like to just let him write it in an editText and then just press a button and send it to me. So that's what I did: 2 classes for the mail thing, my activity which calls it, add the 3 libraries and the internet permission. What did I do wrong?
Here is where I call the email process :
private View.OnClickListener btnMode1Listener = new
View.OnClickListener() {
#Override
public void onClick(View v) {
suggestionText = entre_suggestion.getText().toString();
Log.i("SendMailActivity", "Send Button Clicked.");
String fromEmail = "fromEmail#gmail.com";
String fromPassword = "frompassword";
String toEmails = "toEmail#gmail.com";
List toEmailList = Arrays.asList(toEmails
.split("\\s*,\\s*"));
Log.i("SendMailActivity", "To List: " + toEmailList);
String emailSubject = "Suggestion";
String emailBody = suggestionText;
new SendMailTask(suggestions.this).execute(fromEmail,
fromPassword, toEmailList, emailSubject, emailBody);
}
};
This is the first class "GMail":
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;
List toEmailList;
String emailSubject;
String emailBody;
Properties emailProperties;
Session mailSession;
MimeMessage emailMessage;
public GMail() {
}
public GMail(String fromEmail, String fromPassword,
List 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));
for (Object toEmail : toEmailList) {
Log.i("GMail","toEmail: "+toEmail);
emailMessage.addRecipient(Message.RecipientType.TO,
new InternetAddress((String) toEmail));
}
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.");
}
}
And this is the second class "SendMailtask":
public class SendMailTask extends AsyncTask {
private ProgressDialog statusDialog;
private Activity sendMailActivity;
public SendMailTask(Activity activity) {
sendMailActivity = activity;
}
protected void onPreExecute() {
statusDialog = new ProgressDialog(sendMailActivity);
statusDialog.setMessage("Getting ready...");
statusDialog.setIndeterminate(false);
statusDialog.setCancelable(false);
statusDialog.show();
}
#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(), (List) args[2], 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) {
statusDialog.setMessage(values[0].toString());
}
#Override
public void onPostExecute(Object result) {
statusDialog.dismiss();
}
}
And finally, the 3 librairies I added:
compile files('libs/activation.jar')
compile files('libs/additionnal.jar')
compile files('libs/mail.jar')
So yeah, I searched a lot and didn't find how to debug it. I tried a lot of different ways but it never sent the email. I just want to be clear that I don't want to open the mail app, I want the email to be sent without the user having to do something.

msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(message);
// sends the e-mail
Transport.send(msg);
}
}

add this block in your Class EmailUtility
BodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
try {
messageBodyPart.setContent(message, "text/html; charset=utf-8");
//messageBodyPart.setText(MessageContent);
multipart.addBodyPart(messageBodyPart);
} catch (MessagingException e) {

then replace
msg.setText(message);
with
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setContent(multipart);

Sending mail from service using smtp

My app runs a service which sends and email, this must be transparent for the user, so I use javax.mail.
These are the classes I implement:
JSSEProvider.java
public final class JSSEProvider extends Provider {
private static final long serialVersionUID = 1L;
public JSSEProvider() {
super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");
AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() {
#Override
public Void run() {
put("SSLContext.TLS",
"org.apache.harmony.xnet.provider.jsse.SSLContextImpl");
put("Alg.Alias.SSLContext.TLSv1", "TLS");
put("KeyManagerFactory.X509",
"org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");
put("TrustManagerFactory.X509",
"org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");
return null;
}
});
}
}
MailSender.java
public class MailSender extends javax.mail.Authenticator {
private final String mailhost = "smtp.gmail.com";
private final String user;
private final String password;
private final Session session;
static {
Security.addProvider(new JSSEProvider());
}
public MailSender(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.socketFactor.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");
session = Session.getDefaultInstance(props, this);
}
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
public synchronized void sendMail(String subject, String body, String sender, String recipients) throws Exception {
MimeMessage message = new MimeMessage(session);
DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));
message.setSender(new InternetAddress(sender));
message.setSubject(subject);
message.setDataHandler(handler);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
Transport.send(message);
}
public class ByteArrayDataSource implements DataSource {
private final 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;
}
#Override
public String getContentType() {
if (type == null)
return "application/octet-stream";
else
return type;
}
#Override
public InputStream getInputStream() throws IOException {
return new ByteArrayInputStream(data);
}
#Override
public String getName() {
return "ByteArrayDataSource";
}
#Override
public OutputStream getOutputStream() throws IOException {
throw new IOException("Not Supported");
}
}
}
And finally, this is how I send the email from service:
private void sendEmail(String email) {
String from = "mymail#gmail.com";
String pass = "mypass";
String to = email;
String subject = getString(R.string.email_subject);
String body = text_i_want_to_send;
MailSender mail = new MailSender(from, pass);
try {
mail.sendMail(subject, body, from, to);
Log.d("EMAIL", "Email sent!");
} catch (Exception e) {
Log.d("EMAIL", "Error: " + e.getMessage());
}
}
Now, the problem is that, when it should send the email, I can see in the LogCat the exception refered to the catch statement, but it does not give any details, it just says:
EMAIL Error: null
Have to say that I have goten the JSSEProvider and the MailSender clases from the diferent tutorials around the net about using javax.mail to send mails using smtp.
So, I have no clue about what I'm doing wrong
EDIT --
I have chaught the exception, and it was related to doing network operation on the main thread. So I'm using now an AsyncTask and this part is solved.
But now, I have another exception, related to authentication this time. I have received an email in my email account telling that some has tried to access to my account (me) and that gmail has blocked it. So, how can I solve this authentication issue?

Can you add a catch for a NullPointerException?
(and add throw e).
I guess you have a null pointer somewhere and like this you can have more data.
Therefor it's a bad habit to catch "Exception" as everything will be caught.

How I can instantiate of this appender on my log4j.properties configuration ??

Do you need to programatically add the Appender?

....................... thanks in advance.

Just follow this code; it is really useful to send email into java desktop and it works.

message.setContent(textBody, "text/html");
Transport.send(message);
System.out.println("Done");
}
catch (MessagingException e)
{
e.printStackTrace();
}
}
}

Here is the code snippet to send email.
try {
String host = "yourHostName";
String from = "test#test.com";
String to[] = {"test123#test123.com"};
String subject = "Test";
String message = "Test";
Properties prop = System.getProperties();
prop.put("mail.smtp.host", host);
Session sess1 = Session.getInstance(prop, null);
MimeMessage msg = new MimeMessage(sess1);
msg.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++) {
toAddress[i] = new InternetAddress(to[i]);
}
msg.setRecipients(Message.RecipientType.TO, toAddress);
msg.setSubject(subject);
//Fill the message
msg.setText(message);
Transport.send(msg);
} catch (MessagingException me) {
me.printStackTrace();
}
What exceptions are you getting while sending emails? Are you sure your SMTP server is listening at default port 25? Are you able to manually send the email via Telnet? Also, turn off any firewall while testing this just to be sure.
