Install Android Compatibility package

A few weeks ago, Dianne Hackborn wrote about the new Fragments API, a mechanism that makes it easier for applications to scale across a variety of screen sizes.

The new Fragments API, which is part of Honeycomb, does not help developers whose applications target earlier versions of Android.

Today Google have released a static library that exposes the same Fragments API (as well as the new LoaderManager and a few other classes) so that applications compatible with Android 1.6 or later can use fragments to create tablet-compatible user interfaces. it’s called “Android Compatibility package”.

This library is available through the SDK Updater.
