What should a developer know before building cellphone apps? [closed]

Question

I want to start making cellphone apps with Android as first choice but not the only one. I have 10 years of experience with Java, C#, C++ in commercial applications and I know that many things and practices for this applications are not valid for cellphones. Where do I start reading? How do I adapt my way of thinking to this new environment as quickly as posible? I plan to make some money with it sometime in the future as an extra income or a career change maybe, who know. Any resource or advice you could recommend will be very welcome. Thanks in advance.

Just start with Android Developer site http://developer.android.com/index.html. It contains all you need for the beginning. Also take a look onto Commonsware android books, those are really great both for beginners and experienced programmers - http://commonsware.com/books.html.
