A blog with code examples on developing for Android -> RESTLet (hosted on Google App Engine): http://broschb.blogspot.com/, really nice page, and good examples.
RESTLet have also done an Android example of their own: http://wiki.restlet.org/docs_2.0/13-restlet/275-restlet/266-restlet/269-restlet.html
The general RestLet API http://wiki.restlet.org/docs_2.0/13-restlet/27-restlet.html
Discoveries
It seems that we need to get in depth with the philosophy behind the REST principals, since the frameworks uses a lot of terms derived from the philosophy to describe the inner workings of their framework, like Connectors (Essential), and Ressources.
I think this should be described in the report aswell.
