How do I load my site without the side bars? This is for an app

Do you have access to the theme files? If so, try replacing <?php get_sidebar() ?>; with this:

<?php
if( stristr($_SERVER['HTTP_USER_AGENT'],'android') === FALSE ) {
    get_sidebar();
}
?>

Otherwise, what about access to the theme’s javascript file?

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1;
if(isAndroid) {
    // Do something!
    // Perhaps target the CSS to hide the sidebar (display:none;)?
}

EDIT:

You can also try loading a stylesheet after the default one that targets mobile devices. Use the media attribute when loading the stylesheet:

<link href="https://wordpress.stackexchange.com/questions/31285/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 480px)" />

Alternatively you can just add some declarations into your existing stylesheet:

// target small screens (mobile devices or small desktop windows)  
@media only screen and (max-width: 480px) {  
    /* CSS goes here */  
}
