In this chapter, you'll move past the basics, loosen the leash, and let Android stretch its legs a little bit. More and more as the mobile software field progresses, it's become less and less possible to make an application that doesn't rely heavily on the Web. In many ways, fully featured Internet access has become one of the essentials in the mobile world. The depth and breadth of Android's network layer makes it impossible to cram into one small chapter of one small book. With this in mind, I'll try to, as I have before, arm you with the basics you'll need to make production-level applications. Along the way, as in previous examples, you'll explore a few tangential pieces of Android's technology.
