Detect Android phone via Javascript / jQuery

Take a look at that : http://davidwalsh.name/detect-android

JavaScript:

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid) {
  // Do something!
  // Redirect to Android-site?
  window.location = 'http://android.davidwalsh.name';
}

PHP:

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(stripos($ua,'android') !== false) { // && stripos($ua,'mobile') !== false) {
  header('Location: http://android.davidwalsh.name');
  exit();
}

Edit : As pointed out in some comments, this will work in 99% of the cases, but some edge cases are not covered. If you need a much more advanced and bulletproofed solution in JS, you should use platform.js : https://github.com/bestiejs/platform.js
