Congratulations on your book; the TOC look very impressive!
My question to you is -
1. With Android being ported to an array of devices from playstations to set-top boxes, have you tried developing Android applications for platforms other than cell phones?
2. Do you think for such platforms a separate SDK would be written or will the same SDK suffice?
3. If same SDK is going to be used, I am not sure how screen densities and sizes will be handled by the runtime. Presently, these are general categorization of resources specific to mobile phones.
4. Any special considerations you can think of, for such a development exercise?
