your code working fine in browser not in mobile.

on checking source code seems you're specifying sensor parameter false.

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> 

you missed while checking documentation.

specifying sensor parameter

use of google maps api requires indicate whether application using sensor (such gps locator) determine user's location. especially important mobile devices. applications must pass required sensor parameter tag when including maps api javascript code, indicating whether or not application using sensor device.

applications determine user's location via sensor must pass sensor=true when loading maps api javascript.

hope understand.
