Multi Touch

With each new version of Android, new features are added to the platform. In this part, we'll concentrate on those newer features and on making your programs available to others.

In this chapter, we'll learn how to use the new multi-touch features in Android 2.0, warts and all. Then we'll cover home screen widgets, introduced in Android 1.6, and live wallpaper, introduced in Android 2.1. Android's popularity and its rapid pace of development have created a problem with fragmentation, so there's a whole chapter dedicated to dealing with all the different versions and screen sizes you'll encounter in the field. Finally, there's a chapter that discusses how to get your program into users' hands by publishing it on the Android Market.
