This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
The book is focused on helping new Android developers get-to-grips with good user interface design within the confines of the Android platform. While there is a fair amount of "good design" practiced in the book, it's always related to some part of the Android platform. For example: the chapter on animation details where you want animations, timing, and how it relates to user experience. That said: the example is entirely specific to how Android builds and renders animations.
So while you might well get some useful generic design tricks and information out of it, you'll also be reading a lot that has nothing to do with your target platform.
