HtmlUnit on Android

Question

I have been coding a web scraping application on Android, using HtmlUnit. But, when I build the app, the build error occur \"Conversion to Dalvik format failed with error 1\

Answer 1

I just ran into this, and saw a lot of other errors triggered by XML-related jars, including this:

trouble processing "javax/xml/XMLConstants.class":

Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.

This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.

The problem went away after I removed the xalan, xercesImpl and xml-apis jars from the project (I usually include them with any projects using HtmlUnit on the desktop). Presumably they are colliding with the versions included in the SDK.
