Xavier Le Vourch had made a post describing how to modify the PMD ruleset to be more Android specific. My AndCooper-modified-pmd with his ruleset enclosed(jar download). For AndCooper 0.2 the mdoified PMD will have some more rules specific to Android. You will refer to the ruleset as andcooper.xml in your pmd ant task and you need the ruleset in the jar hence the modified PMD jar download. Sorry for the delay in gettting this out.
