Can you please explain as to when should one use Fragments and when to use Activities ?
Also, I tried creating a multi choice dialog for choosing a phone to connect via bluetooth (which turned out to be a pain on its own), but for some reason the UI look and integration took me quite a while. Does your book provide a walkthrough of the various mobile UI elements that one may require while creating mobile applications? Also, can you suggest any alternative resources for these as the android website although informative, lacks the step by step guidance required for people who are new to android and trying to self learn the fundamentals.
