Support android.util classes to assist with development of applications for android API level 4 or later. The main features here are a variety of classes for handling backwards compatibility with views (for example {@link android.support.v4.view.MotionEventCompat} allows retrieving multi-touch data if available), and a new {@link android.support.v4.view.ViewPager} widget (which at some point should be moved over to the widget package).
