Joomla 2.5: Distinct based on the language website with navigator - joomla

Question

I have a joomla 2.5 bilingual website and I have the following code in index.php
<script type="text/javascript"> // <![CDATA[
if ( (navigator.userAgent.indexOf('Android') != -1) ) {
document.location = "a.html";
} // ]]>
</script>
As a result if you login from your Android phone/tablet it will lead you at the a.html link.
What I wanna do is:
Assume the website's url is the www.test.com/index.php?lang=en so when you login from android it leads you at the a.html and when you login from www.test.com/index.php?lang=fr should lead you at the b.html .
I need to distinct based on the language.
Thanks in advance.

You could maybe use something like this:
<?php
$app = JFactory::getApplication();
$menu = $app->getMenu();
if ($menu->getActive() == $menu->getDefault( 'en-GB' )) { ?>
<script type="text/javascript"> // <![CDATA[
if ( (navigator.userAgent.indexOf('Android') != -1) ) {
document.location = "a.html";
} // ]]>
</script>
<?php }
elseif ($menu->getActive() == $menu->getDefault( 'fr-FR' )) { ?>
<script type="text/javascript"> // <![CDATA[
if ( (navigator.userAgent.indexOf('Android') != -1) ) {
document.location = "b.html";
} // ]]>
</script>
<?php }
?>
Please note I haven't tested this so let me know if it work and if not, I can update it.
Update:
As Oriol said, it's better to redirect server side rather than javascript. I was messing around with the code yesterday and half of what I wrote worked:
<?php
$lang = JFactory::getLanguage();
$app = JFactory::getApplication();
$menu = $app->getMenu();
if ($menu->getActive() == $menu->getDefault( 'en-GB' )) {
?>
<script type="text/javascript">
alert("<?php echo $lang->getTag() ?>");
</script>
<?php
}
elseif ($menu->getActive() == $menu->getDefault( 'fr-FR' )) {
?>
<script type="text/javascript">
alert("<?php echo $lang->getTag() ?>");
</script>
<?php
}
?>
It basically gets the current language tags and alerts then, depending which language the website is being viewed in. So it will either alert en-GB or fr-FR. Try using a server side redirect inside the if and else else statements
