Javascript 为什么detect mobile js在我的网站上不适用于android？

不用赌www.nshaiku.net，我的android浏览器上有一大堆行话似的积垢：适用于iPhone

<script type="text/javascript" src="js/detectmobile.js"></script>
<script>
    try {
        // This is the URL where mobile
        detectmobile.defaultMobileURL = "http://www.nsahaiku.net/mobile.php";
        detectmobile.process();
    } catch (e) {
        // Make sure that in the fault modes
        // we do not interrupt execution of other Javascript code
    }
</script>
