One final question, Karl, and I will leave you be... for now. :-) So I do have Felix working on Android and see things starting to work with bundles being resolved and activated, which is good, so I know I can get a static container running (once I modify my jars for commons logging).
Is it possible to refresh a bundle under Felix on Android so that a new version of the bundle comes in from the outside and gets itself properly setup? Or, because of the way that Dalvik works, can you only run a static OSGi container with a set of start bundles and maybe a deploy of a new bundle, but no updating an old bundle?
