Android WebView not loading a JavaScript file, but Android Browser loads it fine

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.

More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.

Also for this application I've slimmed my landing page, so I could give you the source to offer me aid.

The background Application is my app, running in an emulator. The top application is the browser. You'll see the browser has the firebug icon, and can activate the firebug, but the application does not have the firebug icon. http://img413.imageshack.us/img413/9628/myapp.gif

My Application is running in the background, and as you can see n开发者_开发知识库o Firebug in the lower right hand corner. However the browser (the emulator on top) has the same page but shows the firebug. What am I doing wrong? I'm assuming its either not enough memory allocated to the application, process power allocation, or a physical memory thing. I can't tell, all I know is the results are strange.

I get the same thing form my android device, the application shows no firebug but the browser shows the firebug.

I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.

Works just great for me. I can see FireBug icon in WebView.

This line is evil, I guess you should remove it:

webview.getSettings().setUserAgentString(OverideUserAgent_IE);
