Yep! Not exactly a huge advancement, but hey, it's something else to show off. Unit listing and detail views were the first thing I wanted to get running, partially to make sure I was actually getting the right info from the server, and partially to have something to look at for encouragement as I start getting into the actual difficult parts.
After some TIGSource forum members generously helped me figure out that the stat-graph-thing I wanted to do is a radar chart, I found a couple Android libraries that might make generating those a pretty easy prospect, which I will definitely look into.
So yeah, nothing terribly exciting, but another step in the right direction. I think I'm going to start working on the battle system next, just to sink my teeth into something really difficult and interesting; it'll really push the issue of efficiency in request and response handling on both ends.
