How do you load Javascript into android webview?

Question

HTML code:

<!DOCTYPE html>
    <html>
        <head>
            <script src="resource://jquery.min.js"></script>
        </head>
        <body>
        </body>
    </html>

I want to intercept the protocol(resource://) and manual load Javascript into the webview. So I can store third party libs in android assets.

I tried override onLoadResource of WebViewClient and then use webView.loadData(data, mimeType, encoding); But it didn't work because the app went into a endless loop.

I'd suggest reading through the PhoneGap (Now Cordova) source code. They've been doing this for a while now. — jmcdale
@jamn224 I tested phonegap but it does't work. I move the index.html to my web server and modify the script tag like this: <script type="text/javascript" src="file:///android_asset/www/cordova-2.6.0.js"></script> — Seaborn Lee

Found the answer, and it works perfectly! I have searched this question many times via google and stackoverflow but haven't got the right answer. And finally my roommate made it happen with just the first trying.
