Hello
I have created a mailing list for osmdroid, the open-source Android map engine that AndNav2 uses (org.andnav2.osm).
There are already at least 9 apps that use osmdroid. So far everyone has copied the code into their own repository but osmdroid can now be used as a convenient .jar file. By keeping the osmdroid source separated, all projects can take advantage of the common development.
You're welcome to stay in the loop on the continued osmdroid development by joining:
Regards
Anders Petersson
