QuestionAndroid Homepage Link Touch Icon Problem Pin

We desperately need some help. We're having some terrible problems with a touch icon for Android. Everything works perfectly on an iPhone but we've been battling with Android for over a week and it absolutely refuses to work. The touch icon created on one Android appears pixelated and on another it appears very small.

Following Apple's guidelines we created the following touch icons - I've given the full URLs for the files so that you can see them - they're publicly available on a live web server:

http://www.faclair.com/apple-touch-icon-precomposed.png
http://www.faclair.com/apple-touch-icon-57x57-precomposed.png
http://www.faclair.com/apple-touch-icon-72x72-precomposed.png
http://www.faclair.com/apple-touch-icon-114x114-precomposed.png
http://www.faclair.com/apple-touch-icon-144x144-precomposed.png

As per Apple guidelines, each icon is the sise described in its filename.

The mobile version of our system

http://www.faclair.com/m/[^]

has the following HTML:
HTML
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link rel="apple-touch-icon-precomposed" href="http://www.faclair.com/apple-touch-icon-precomposed.png" />
<link rel="apple-touch-icon-precomposed" sizes="57x57" href="http://www.faclair.com/apple-touch-icon-57x57-precomposed.png" />
<link rel="apple-touch-icon-precomposed" sizes="72x72" href="http://www.faclair.com/apple-touch-icon-72x72-precomposed.png" />
<link rel="apple-touch-icon-precomposed" sizes="114x114" href="http://www.faclair.com/apple-touch-icon-114x114-precomposed.png" />
<link rel="apple-touch-icon-precomposed" sizes="144x144" href="http://www.faclair.com/apple-touch-icon-144x144-precomposed.png" />


We're aware that some versions of Android require the full URL to be specified so we've done that. We're also aware that some versions of iPhone and Android can't read the sizes attribute so we tried a default apple-touch-icon-precomposed.png file at both 144x144 and 57x57 but neither worked.

We suspect that Android might have some incorrect caching behavior because nothing we do can make Android change the favicon it is using (clearing the browser cache doesn't help). Even changing to a completely different image in the png file on the server it appears to be impossible to make Android change the image it uses - deleting the webpage link on the home screen, deleting the browser favorite, clearing the browser cache and re-creating the home screen link it still uses the same icon regardless of the icon file on the server.

The application has a favicon and we suspect that Android may be incorrectly using that instead of one of the touch icon files.

What makes the situation worse is that when we first tried this we didn't follow Apple's naming conventions and it worked on an iPhone and one out of two Androids. We changed to comply with Apple's recommendations in the hope of getting it to work on both Android devices. The above works on the iPhone but neither of the Android phones (on one the icon ix pixelated and on the other it is very small).

All devices are physical devices - not emulators.

We'd be very grateful for any help.
