Hi Mitch. Thanks for great tutorials. I am your big fan ;) Could you do course on bluetooth connections? To make it easier, maybe with other mobile phone and some interactions between them. Like some simple chat or some simple 2-player game. Also I would appreciate if you could do some course about Android services and how to use them. Maybe some mp3 player, even when app is minimized? I haven't gone through all of your courses yet, so maybe there is something like this already there. Anyway, thanks for good couses. Regards. Peter
