The Android SDK version 1.5 has been “pre-released”. Pros: lots of cool stuff in there including both new features and improvements on existing functionality. Cons: moving target!
All in all, Android continues to impress me. I am working on a project presently which uses the different Hardware “Sensors” in the device. Very cool to have access to this kind of stuff.
Fortunately, it looks like the contents of the Unlocking Android book are still quite applicable.
