what is best way to learn android [closed]

view story

http://stackoverflow.com – I have been programming for 40 years in COBOL, C++, C#, PHP, javascript, html, Visual Studio, etc. and am trying to learn programming for the Android platform. I always thought I could pick up anything but Android has me reeling trying to learn it using Eclipse. Does anyone have any recommendations on IDE's or books to buy to use for developing Android for someone not familiar with Android? The books I bought to learn Android mention terms like 'final' and I have no idea what the hell that means. I guess I need a basic primer. Am I getting senile or is Android a tough nut to crack? Any f (HowTos)
