Chapter 8: Programming with the Device H... > Getting Turn-by-Turn Directions

Getting Turn-by-Turn Directions

I'm sure that by now, you are thinking that Android has great features in the operating system, and you are ready to start using them. So, let's take two features presented in the chapter, voice recognition and the sensors, to produce a turn-by-turn set of driving directions, or navigation from the current point.

One of the great features of mobile devices is that they are, in fact, mobile. This opens myriad options. Imagine that the user is getting into his or her car. You want the phone to provide a set of turn-by-turn directions, but only once the device is on a magnetic plate in the user's car. Once the device is placed on that magnetic plate, the user is presented with driving directions to the location from the current location.
