I spent half of the day getting my Android app, "Tag Your World", to download locations from my Google App Engine application! And it works!
Okay, it's not perfect, mind you. I'm not authenticating or anything so I'm just pulling down the "public" info. However, Lenza just posted some code on how to do that so I should have no problem! Thank you, Lenza!
Now I can finish my presentation for this Thursday (although I'd really like to hack some more ;-)!
