Sending HTTP POST Request TO WEBSITE from Android

I'm trying to connect this site : http://ift.tt/ox9627 via android studio. My goal is to authenticate email addresses. so i'd like to use the form in this site in order to do so. Notice : it is not mine.

This is the Form part :

<form id="myForm" method="get" class="form-inline searchform form-validate" action="index.php">
                            <input id="checkemail" type="email" value="" name="check" class="required validate-email span5" placeholder="emailtoverify@domain.com" required="">
                            <input type="hidden" name="option" value="com_emailverifier">
                            <input type="hidden" name="view" value="emailverifier">
                            <input type="hidden" name="layout" value="verify">
                            <input type="hidden" name="format" value="raw">
                            <input type="hidden" name="d046d088e65dec63e8fd1cd1db4c32db" value="1">                         <input class="submit btn btn-large btn-danger span3" id="btn" type="submit" name="submitEmail" value="Verify">
<!--                            <a class="btn btn-small btn-success" href="http://ift.tt/2cAC8Qw">More about this email...</a>-->
                            <div id="loading" style="display: none;">Verifying... Please wait...</div>
                        </form>

<form action="/#result" method="post">
