The Android Support Library provides backward-compatible versions of Android framework APIs as well as features that are common for multiple Android versions like Fragments and Loaders. It was first released in March 2011 and is currently in version 11 released in November 2012. It includes classes for Fragments, FragmentManager, LoaderManager, and more that provide consistent behavior across Android versions.
