Send Email Programmatically in Android

So I am trying to send an email in Android without using Intent because I need it to be sent in the background. I am following this post,

I have the .jars added as part of the build path.

And I have this code as the class

package cistoran.partyPlanner;

import java.util.Date; 
import java.util.Properties; 
import javax.activation.CommandMap; 
import javax.activation.DataHandler; 
import javax.activation.DataSource; 
import javax.activation.FileDataSource; 
import javax.activation.MailcapCommandMap; 
import javax.mail.BodyPart; 
import javax.mail.Multipart; 
import javax.mail.PasswordAuthentication; 
import javax.mail.Session; 
import javax.mail.Transport; 
import javax.mail.internet.InternetAddress; 
import javax.mail.internet.MimeBodyPart; 
import javax.mail.internet.MimeMessage; 
import javax.mail.internet.MimeMultipart; 


public class Mail extends javax.mail.Authenticator { 
  private String _user; 
  private String _pass; 

  private String[] _to; 
  private String _from; 

  private String _port; 
  private String _sport; 

  private String _host; 

  private String _subject; 
  private String _body; 

  private boolean _auth; 

  private boolean _debuggable; 

  private Multipart _multipart; 


  public Mail() { 
    _host = "smtp.gmail.com"; // default smtp server 
    _port = "465"; // default smtp port 
    _sport = "465"; // default socketfactory port 

    _user = ""; // username 
    _pass = ""; // password 
    _from = ""; // email sent from 
    _subject = ""; // email subject 
    _body = ""; // email body 

    _debuggable = false; // debug mode on or off - default off 
    _auth = true; // smtp authentication - default on 

    _multipart = new MimeMultipart(); 

    // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added. 
    MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap(); 
    mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html"); 
    mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml"); 
    mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain"); 
    mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed"); 
    mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822"); 
    CommandMap.setDefaultCommandMap(mc); 
  } 

  public Mail(String user, String pass) { 
    this(); 

    _user = user; 
    _pass = pass; 
  } 

  public boolean send() throws Exception { 
    Properties props = _setProperties(); 

    if(!_user.equals("") && !_pass.equals("") && _to.length > 0 && !_from.equals("") && !_subject.equals("") && !_body.equals("")) { 
      Session session = Session.getInstance(props, this); 

      MimeMessage msg = new MimeMessage(session); 

      msg.setFrom(new InternetAddress(_from)); 

      InternetAddress[] addressTo = new InternetAddress[_to.length]; 
      for (int i = 0; i < _to.length; i++) { 
        addressTo[i] = new InternetAddress(_to[i]); 
      } 
        msg.setRecipients(MimeMessage.RecipientType.TO, addressTo); 

      msg.setSubject(_subject); 
      msg.setSentDate(new Date()); 

      // setup message body 
      BodyPart messageBodyPart = new MimeBodyPart(); 
      messageBodyPart.setText(_body); 
      _multipart.addBodyPart(messageBodyPart); 

      // Put parts in message 
      msg.setContent(_multipart); 

      // send email 
      Transport.send(msg); 

      return true; 
    } else { 
      return false; 
    } 
  } 

  public void addAttachment(String filename) throws Exception { 
    BodyPart messageBodyPart = new MimeBodyPart(); 
    DataSource source = new FileDataSource(filename); 
    messageBodyPart.setDataHandler(new DataHandler(source)); 
    messageBodyPart.setFileName(filename); 

    _multipart.addBodyPart(messageBodyPart); 
  } 

  @Override 
  public PasswordAuthentication getPasswordAuthentication() { 
    return new PasswordAuthentication(_user, _pass); 
  } 

  private Properties _setProperties() { 
    Properties props = new Properties(); 

    props.put("mail.smtp.host", _host); 

    if(_debuggable) { 
      props.put("mail.debug", "true"); 
    } 

    if(_auth) { 
      props.put("mail.smtp.auth", "true"); 
    } 

    props.put("mail.smtp.port", _port); 
    props.put("mail.smtp.socketFactory.port", _sport); 
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
    props.put("mail.smtp.socketFactory.fallback", "false"); 

    return props; 
  } 

  // the getters and setters 
  public String getBody() { 
    return _body; 
  } 

  public void setBody(String _body) { 
    this._body = _body; 
  }
  public void setTo(String[] toArr) {
      this._to = toArr;
  }

  public void setFrom(String string) {
      this._from = string;
  }

  public void setSubject(String string) {
      this._subject = string;
  }

  // more of the getters and setters ….. 
} 

And I have this code as my sendEmail method that is activated by clicking a button in the menu.

public void sendEmail()
{
    EditText childNameBox = (EditText) findViewById(R.id.childNameBox);
    EditText parentNameBox = (EditText) findViewById(R.id.parentNameBox);
    EditText phoneNumberBox = (EditText) findViewById(R.id.phoneNumberBox);
    EditText ageBox = (EditText) findViewById(R.id.ageBox);
    EditText notesBox = (EditText) findViewById(R.id.notesBox);
    EditText colorsBox = (EditText) findViewById(R.id.colorsBox);
    EditText dateBox = (EditText) findViewById(R.id.dateBox);
    EditText timeBox = (EditText) findViewById(R.id.timeBox);

    childName = childNameBox.toString();
    parentName = parentNameBox.toString();
    childAge = ageBox.toString();
    phoneNumber = phoneNumberBox.toString();
    colorChoice = colorsBox.toString();
    notesText = notesBox.toString();
    dateDay = dateBox.toString();
    timeDay = timeBox.toString();

    emailCombined = childName + bN + parentName + bN + childAge + bN + phoneNumber + bN + colorChoice + bN + notesText + bN + dateDay + bN + timeDay;
    Mail m = new Mail("emailaddress", "password"); 

    String[] toArr = {"TOEMAIL@gmail.com.com", "FROMEMAIL@gmail.com"};
    m.setTo(toArr);
    m.setFrom("FROMEMAIL@gmail.com"); 
    m.setSubject("Party Booked"); 
    m.setBody(emailCombined); 

    try { 
      //m.addAttachment("/sdcard/filelocation"); 

      if(m.send()) { 
        Toast.makeText(PartyPlannerActivity.this, "Sent Email.", Toast.LENGTH_LONG).show(); 
      } else { 
        Toast.makeText(PartyPlannerActivity.this, "Email was not sent.", Toast.LENGTH_LONG).show(); 
      } 
    } catch(Exception e) { 
      //Toast.makeText(MailApp.this, "There was a problem sending the email.", Toast.LENGTH_LONG).show(); 
      Log.e("PartyPlannerActivity", "Could not send email.", e); 
    } 
}

And here is the LogCat I got from it

Any help would be greatly appreciated.

Add the INTERNET permission to your manifest.

Did you miss INTERNET permission at your AndroidManifest.xml file?

You probably need to add the INTERNET permission to your app.

You need the android.permission.INTERNET permission in your manifest to enable your application to open a network socket.

Insert this code in your manifest file:

<uses-permission android:name="android.permission.INTERNET"/>
