Click On Button Then Automaticly Send Email In Android

I have an xml file which user will enter an email into it, then when click on the submit button, I want the application to automatically send an email with specific content to that

Solution 1:

In my case I used Java Mail API and the code below you can use. Please add the necessary details like user name,password, email ids etc Use this tutorial http://www.jondev.net/articles/Sending_Emails_without_User_Intervention_%28no_Intents%29_in_Android

publicclassMailextendsjavax.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; 

  privateboolean _auth; 

  privateboolean _debuggable; 

  private Multipart _multipart; 


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

    _user = "username"; // username 
    _pass = "password"; // password 
    _from = "emailsentfrom@gmail.com"; // email sent from

    _to = newString[] {"toemail@gmail.com"}; 
    _subject = "subject"; // email subject 
    _body = "test"; // email body 

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

    _multipart = newMimeMultipart(); 

    // There is something wrong with MailCap, javamail can not find a handler for the multipart/mixed part, so this bit needs to be added. MailcapCommandMapmc= (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); 
  }  
  publicMail(String user, String pass) { 
    _user = user; 
    _pass = pass; 
  } 

  publicbooleansend()throws Exception { 
    Propertiesprops= _setProperties(); 

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

      MimeMessagemsg=newMimeMessage(session); 

      msg.setFrom(newInternetAddress(_from)); 

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

      msg.setSubject(_subject); 
      msg.setSentDate(newDate()); 

      // setup message body BodyPartmessageBodyPart=newMimeBodyPart(); 
      messageBodyPart.setText(_body); 
      _multipart.addBodyPart(messageBodyPart); 

      // adding attachment
      addAttachment("filename");//replace with file name u need// Put parts in message 
      msg.setContent(_multipart); 

      // send email Transporttransport= session.getTransport("smtps");
      transport.connect(_host, 465,_user, _pass);
      Transport.send(msg); 

      returntrue; 
    } else { 
      returnfalse; 
    } 
  } 

  publicvoidaddAttachment(String filename)throws Exception { 
    BodyPartmessageBodyPart=newMimeBodyPart(); 
    DataSourcesource=newFileDataSource(filename); 
    messageBodyPart.setDataHandler(newDataHandler(source)); 
    messageBodyPart.setFileName(filename); 

    _multipart.addBodyPart(messageBodyPart); 
  } 

  @Overridepublic PasswordAuthentication getPasswordAuthentication() { 
    returnnewPasswordAuthentication(_user, _pass); 
  } 

  private Properties _setProperties() { 
    Propertiesprops=newProperties(); 

    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"); 
    props.put("mail.smtp.starttls.enable", "true");

    return props; 
  } 

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

  publicvoidsetBody(String _body) { 
    this._body = _body; 
  } 

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

and write an Async task to send mail

publicclassSendTaskextendsAsyncTask<String, Integer, Integer> {

privateProgressDialog dialog;
privateContext mContext;

publicSendTask(Context mContext){
    this.mContext = mContext;

}

protectedvoidonPreExecute() {
    this.dialog = newProgressDialog(mContext);
    this.dialog.setCancelable(false);
    this.dialog.setMessage("sending");
    this.dialog.show();
}

protectedIntegerdoInBackground(String... ids) {

    Mail mail = newMail();
    try {
        mail.send();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return1;
}

}

Solution 2:

In the xml file for your button, define android:onClick="SendMail"

This will call the SendMail function inside your activity when your button is clicked.

Next, get a reference to the EditText view where the user enters the email body.

E.g.: If the resource id of your EditText view is edittext1, then in your activity you need to do the following:

EditText ed=(EditText)findViewById(R.id.edittext1);

String emailBody=ed.getText().toString();

Now the emailBody string consists of the body of the mail that the user has typed in.

Next, inside your activity, you need to define a function SendMail() as shown below:

voidSendMail(String body) {
   String recipient="usrname@mail.com";
   String subject="Your subject here";
   Intenti=newIntent(Intent.ACTION_SEND);
   i.setType("message/rfc822");
   i.putExtra(Intent.EXTRA_EMAIL  , recipient);
   i.putExtra(Intent.EXTRA_SUBJECT, subject);
   i.putExtra(Intent.EXTRA_TEXT   , body);
   try {
      startActivity(Intent.createChooser(i, "Send mail..."));
    } catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
    }
}

This approach has helped me, hope it helps you also.
