Best place to learn android

[nmpku]

I have been programming for almost 9 years now. I am really looking at developing my first android app. Was wondering what is the best tool (tutorial) for learning Android, be it book, online, etc.?

http://code.google.com/android for the sdk and some introduction tutorials.

http://code.google.com/p/apps-for-android/ has some sample open source applications showcasing Android features.

I bought the Pragmatic Programmers book "Hello Android" (http://www.pragprog.com/titles/eband/hello-android) (currently beta PDF only). It is quite good as a intro and a bit further.
