Android SDK + eBay SDK

I haven't done anything with Android in a while, so I thought I would see whether I could get my phone talking to eBay. I grabbed the eBay SDK for Java, stuck it in my project, wrote a small demo app, tried it out, and BOOM!

It looks like it depends on a Swing class (EventListenerList), but Swing isn't available on Android. I guess I'm rolling it by hand then. It's actually unfortunate that EventListenerList is a part of Swing - it looks generic enough that maybe it should be promoted to the core library. For that matter, I'm a little surprised that this made it past the apk builder. Perhaps that is outside the scope of the apk builder.
