I forgot to ask this question previously, but does the book also talk about designing applications to handle orientation changes? I did not see a specific chapter on this; perhaps it is discussed within another chapter. I know that the book isn't focused on layout, but handling orientation changes is applicable to both phones and tablets.
Yes! We do cover orientation changes. Really configuration changes since the current activity can be restarted for any change in configuration, not just orientation changes. The Services chapter talks about it in detail, with examples.
