Default HtmlUnit for Android

I'm developing an app and I need to retrieve data from html code. In addition, i would like manage the event (for example, click the button and redirect in other page) in html code.
I searched on Google and I've found a beautiful library that meet my needs: HtmlUnit.
The problem is the compatibility with Android SDK: there are conflicts with Android classes and maybe, I must to recompile the source code for Android compatibility.
Are there alternative to HtmlUnit? I don't know how to build this library...Can you help me?

Any help would be most welcome...thank you!

PS: sorry for my poor english!
