I was recently able to solve this problem. I displayed an image saved
on the local file system in a WebView, the steps are same for html
file as well.

I wrote about it step by step here
http://www.techjini.com/blog/2009/01/10/android-tip-1-contentprovider-accessing-local-file-system-from-webview-showing-image-in-webview-using-content/

you dont need to implement the ContentProvider in so much details just
one method.
