Login does not work with AsyncTask in Android

I am sitting an small Android app to check the user login information. I have been working on this with no luck. I appreciate if someone can help me with this. Thanks in advance. I am getting this error login_invalid_error with an okay button under.

this is my php.

    <?php 
    $emailAddress;
    $password;

    // Change the following settings based on your db
    // Im assuming your are using MySQL
    $dbHost = "localhost";

    $dbUser = "root";
    $dbPassword = "123456";
    $userTableName = "tb_users";

    // check if params 'emailAddress' and 'password' are set.
    if (isset($_REQUEST['emailAddress']) &&
        isset($_REQUEST['password']))
    {
        $con =  mysql_connect($dbHost ,$dbUser,$dbPassword);
        if(!$con) die('Error ' . mysqli_connect_error);

        mysql_select_db("andrioldlogin",$con) or die("can't select the database");
        $emailAddress = $_REQUEST['emailAddress'];
        // Compares passwords based on md5 encryption.
        $password = $_REQUEST['password'];



        // SQL statement assuming your user table has fields 
        // "email_address" and "password"
        $sql =  "SELECT id FROM tb_users WHERE email_address = '$emailAddress' AND password = '$password'";
        $result = mysql_query($sql);

        if($result)
        {
            $row = mysql_num_rows($result);
            if($row == 1)
            {
                // 202 header code response if there is a matching row.
                header("Status: 202 Accepted");
                // $row[0] will be id from user logging in
                die($row[0]);           
            }
            else
            {
                header("Status: 401 Unauthorized");
                echo "Error logging in 1.";
            }
        }
        else
        {
            header("Status: 401 Unauthorized");
            echo "Error logging in 2.";
        }
    }
    // if values are unset
    else
    {
        header("Status: 401 Unauthorized");
        echo "Invalid Data.";
    }

In doInBackground you cannot update any UI (basic Async fundamentals). So these lines progressDialog.setMessage("Logging in.. ("+(executeCount+1)+"/5)"); and Log.d("Sabawon You are here bro", "statusCode: " + responseCode); and e.printStackTrace(); need to go into a doProgressUpdate or a doPostExecute
