ZXing Barcode Scanner for Webapps

I am trying to use http://zxing.appspot.com/scan to call a barcode scanner from WebApp, but I cannot get it to work. Even after unnecessarily updating and reinstalling, all it does is show the default zxing webpage, which asks me to install a barcode scanner on my phone. Did I miss something?

Here's the javascript that I use to invoke the ZXing scanner. For testing purposes, I even tried to make a simple HTML hyperlink without success. I use Android WebViewto download the application.

window.location.href = 
"http://zxing.appspot.com/scan?ret=http://192.168.1.33:3000/pallet/{CODE}/change_position/"+positionId+"&SCAN_FORMATS=CODE_39";

And this is the manifest of the barcode scanner that identifies and launches the scanner through the browser:

<intent-filter>
    <action android:name="android.intent.action.VIEW"/>
    <category android:name="android.intent.category.DEFAULT"/>
    <category android:name="android.intent.category.BROWSABLE"/>
    <data android:scheme="http" android:host="zxing.appspot.com" android:path="/scan"/>
</intent-filter>

It's funny http://www.google.com/m/products/scanthat doing the same thing works great. Any help or idea is greatly appreciated! Many thanks!

It looks like you are sending an image URL on your local network (192.168 ... IP address) that zxing.appspot.com will not be able to access over the Internet.
