I purchased an Android phone a few weeks ago. Part of the reason that I got it was that I wanted to see what the differences were between Android and iPhone.  This extends out to how to program them as well, so I had to write an application, just like I did for iPhone. Last night, I released my little application.  Its a usage meter for my ISP, Internode. I deliberately chose something quite simple so that I could cut my teeth on the platform, and I must say that I'm very impressed.
