Cordova app cannot load any files in assets/www (only index.html)

I'm compiling a very simple Cordova app and deploying on Android. I want to test the smoothness of jQuery Mobile on various Android devices, so I'm compiling an app with the contents of the jQuery Mobile demo folder.

I created a new Cordova project and placed the contents of jQuery Mobile demo folder into my www folder.

I then used the Cordova binary to add the android platform, ran cordova build, and finally cordova run android.

The application opened on my phone, but no files other than the index.html will load. I connected up the app to the Chrome Inspector debugger to see what wasn't loading, here's what I saw:

All of the files that Cordova can't find, do exist in platforms/android/assets/www. Cordova can find index.html just find, but it cannot load anything else.

If I open that folder in a web browser, everything loads just fine.

Anyone know what could be causing this issue or what steps I might take to further troubleshoot and isolate the issue? I've Googled for hours and I cannot find anyone else facing a situation quite like this. For other people, it's the index.html file that won't load or they simply forgot to add the files they want into the www folder. In my case, index.html loads fine, but nothing else will (see screenshot above).

Here is my config.xml (mostly just the standard default):

<?xml version='1.0' encoding='utf-8'?>
<widget id="com.rand.jqmdemo" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
