AndCooperANT release 0.1 is out, just download the source and follow directions in readme in how to set it up. I have not tested it with Android Library Projects yet but it does support the standard 3rd party library jars. default target to get the code reports is debug with it producing javadocs, checkstyle, pmd, and classycle reports.
Next up is to do Test Project support, Android Library Project support, and multiapkexport support. Two other issues. PMD 4.x is used right now but will be updated to use PMD 5 shortly. And there are two proguard config files included the one mentioned in the android dev blog post on Sept 21 and a longer one that includes options to strip out log statements.
