Sending Android (tablets and phones) to custom tailored pages (or direct links to video that is optimized for their screens) is a really good idea.

Redirect Android:

Here’s a few methods. One tactic, and a nice simple code (not written by us) is to start with splitting android phones from tablets then moving on to redirecting by operating system.

Javascript Redirect: Split Android phones from Android tablets

*******************************************

First, let’s split the phones from the tablets. Here’s a script that allows you to seperate android phones from android tablets:

<!-- android phone or tablet? better figure it out, or everything degrades  into chaos... -->
&lt; script language="javascript"&gt; <!--
var mobile = (/iphone|ipad|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent.toLowerCase()));
if (mobile) {
alert("MOBILE DEVICE DETECTED");
document.write("<b>----------------------------------------
")
document.write("<b>" + navigator.userAgent + "
")
document.write("</b><b>----------------------------------------
")
var userAgent = navigator.userAgent.toLowerCase();
if ((userAgent.search("android") > -1) &#038;&#038; (userAgent.search("mobile") > -1))
document.write("</b><b> ANDROID MOBILE 
")
else if ((userAgent.search("android") > -1) &#038;&#038; !(userAgent.search("mobile") > -1))
document.write("</b><b> ANDROID TABLET 
")
}
else
alert("NO MOBILE DEVICE DETECTED"); //--> 
<!-- android phone or tablet? now we know, and we will not fall into the abyss... --></b>

Simple Android redirect

*******************************************


Here’s a simple redirect, if your needs are straightforward, simple is good:

1

<!-- <span class="hiddenSpellError" pre="">javascript android redirect example 1 -->
<a>text/javascript</a>'&gt;
var ua = navigator.userAgent.toLowerCase();
 var isAndroid = ua.indexOf("android") &gt; -1; //&amp;&amp; ua.indexOf("mobile");
 if(isAndroid) {
 // you know you have an android that just hit your page, where you going to send it?
 window.location = 'http://gravlab.com/rockandroll/';
 }
 
<!-- END javascript android redirect example 1 -->

So that one’s nice and easy. If you just need Android phones and tablets to get their own special webpage… Why overcomplicate it? Here’s the one that gravitylab usually uses, we can send a few devices to different players, and some devices directly to a video or video metafile like m3u8. It’s nice to have options!

<!-- <span class="hiddenSpellError" pre="">javascript android redirect example 2 -->start here: detect device   <script type="text/javascript">// < ![CDATA[
// < ![CDATA[     if (navigator.userAgent.indexOf('iPhone') != -1) {         document.location = "http://client.gravlab.net/009999/auto_encoded/iOS/video/yourHLSvideo.m3u8";     }     if (navigator.userAgent.indexOf('iPad') != -1) {         document.location = "http://client.gravlab.net/009999/auto_encoded/iOS/video/yourHLSvideo.m3u8";     }     if (navigator.userAgent.indexOf('iPod') != -1) {         document.location = "http://client.gravlab.net/009999/auto_encoded/iOS/video/yourHLSvideo.m3u8";     }     if (navigator.userAgent.indexOf('Blackberry') != -1) {         document.location = "http://client.gravlab.net/009999/auto_encoded/blackberry/yourHLSvideo.mp4";     }     if (navigator.userAgent.indexOf('Android') != -1) {         document.location = "html5.html";     }
// ]]></script><!-- END javascript android redirect example 2 -->

Here’s one that is basically a mini database of phones, quite impressive. Available on Google Code, and developed by MobileESP:

/* *******************************************
// Copyright 2010-2012, Anthony Hand
//
// File version date: April 23, 2012
// Update:
// - Updated DetectAmazonSilk(): Fixed an issue in the detection logic.
//
// File version date: April 22, 2012 - Second update
// Update: To address additional Kindle issues...
// - Updated DetectRichCSS(): Excluded e-Ink Kindle devices.
// - Created DetectAmazonSilk(): Created to detect Kindle Fire devices in Silk mode
// - Updated DetectMobileQuick(): Updated to include e-Ink Kindle devices and the Kindle Fire in Silk mode.
//
// File version date: April 11, 2012
// Update:
// - Added a new variable for the new BlackBerry Curve Touch (9380): deviceBBCurveTouch.
// - Updated DetectBlackBerryTouch() to support the new BlackBerry Curve Touch (9380).
//
// File version date: January 21, 2012
// Update:
// - Moved Windows Phone 7 to the iPhone Tier. WP7.5's IE 9-based browser is good enough now.
// - Added a new variable for 2 versions of the new BlackBerry Bold Touch (9900 and 9930): deviceBBBoldTouch.
// - Updated DetectBlackBerryTouch() to support the 2 versions of the new BlackBerry Bold Touch (9900 and 9930).
// - Updated DetectKindle() to focus on eInk devices only. The Kindle Fire should be detected as a regular Android device.
//
// File version date: August 22, 2011
// Update:
// - Updated DetectAndroidTablet() to fix a bug introduced in the last fix! The true/false returns were mixed up.
//
// File version date: August 16, 2011
// Update:
// - Updated DetectAndroidTablet() to exclude Opera Mini, which was falsely reporting as running on a tablet device when on a phone.
// - Updated the user agent (uagent) init technique to handle spiders and such with null values.
