Hello Dave and Satya, I really enjoy the fact that you are here to respond to some of the questions about your book,
because I'm really interested in starting right in these days to learn Android programming.

My way of learning is focused primarily on practice, what kind
of example have you choosen for this book? I mean, are they practical examples or much more teaching?

Thank you!

Marco,

For good or bad these are "teachable" simple examples that demonstrate the concepts of that particular chapter. They are stand alone and simple.

Here is a list of these samples: Pro Android 3 Downloadable Projects

I would say that we have a mixture of sample apps, but most are purely for teaching. For example, I have an app in the Touchscreen chapter that is meant to demonstrate how the events fire as fingers touch the screen, touch buttons, and drag. Definitely *not* a practical sample app. But in the Services chapter, there's an app that will convert a text string from one language to another (using the Google Translate API in service calls). There's a drag and drop example on the Android Developer web site that is very simple and takes some shortcuts. I did a sample drag and drop application for chapter 31 that is more like a real app in that there are several objects that can be dragged, and I discovered some useful information that is shared in the book, information you don't get by running Android's sample app.

The main thing we tried to do in our samples was really demonstrate the concept of the chapter topic, to show how it really works, in as close to a real situation as we could for that particular feature. The reason they're not true practical applications is because they're missing all the other stuff that a truly practical app should have. We just couldn't build them all this way or the book would have 2000+ pages, and it would be harder to see how the one feature really works.
