Android : Way To Access Google Products Search Within Droid-App?

I wanna use the Gdata Apis within my Android Application. Being more specific I wanna give the user the ability to search for keywords, use the Gdata api to search for products within googleproducts for these keywords and parse the xml that I get back. I know how to parse xml files via an org.xml.sax.helpers.DefaultHandler but I guess that I am not suppose to use such a Handler but rather rely on the Gdata api to parse the xml for me. My Problem is that I dont know how to integrate the api in my App. There is a similiar topic within stackoverflow (hier) but I am not at all satisfied with the answer they gave. Just giving someone the information to "look at our recently announced version 2.1.0-alpha of the GData Java library which supports Android" doesnt quite help me to integrate gdata in my app. I would very appreciate if someone could give a step-by-step guide how to integrate the gdata api within my app, including code examples to make a search-request and parsing back the results from google products.
