The following is the first few sections of a chapter from The Busy Coder's Guide to Android Development, plus headings for the remaining major sections, to give you an idea about the content of the chapter.


NFC

NFC, courtesy of high-profile boosters like Google Wallet, is poised to be a significant new capability in Android devices. While at the time of this writing, only a handful of Android devices have NFC built in, other handsets are slated to be NFC-capable in the coming months. Google is hoping that developers will write NFC-aware applications to help further drive adoption of this technology by device manufacturers.

This, of course, raises the question: what is NFC? Besides being where the Green Bay Packers play, that is?

(For those of you from outside of the United States, that was an American football joke. We now return you to your regularly-scheduled chapter.)
