Android app development

I have been thinking of this for quite sometime, and I guess this is the right time. I have designed a small step by step course to setup and learn android. Srishti was interested in going ahead with it. My plan is to give links here in this thread, and discuss all the specific problems that we face during the development here. I thought it would be a great way for all of us to guide (and little bit misguide :)) each other.
