is a library to implement common UIs easily. Available UI types are: tabbed UI (TabActivity), master/metail flow (SectionActivity) and their hybrid (HybridActivity). These activity classes wrap everything you need to create your UI with just a few lines of code or even load tabs/sections and instaniate fragments from XML file. HybridActivity allows you to have tabs on phones and MDF on tablets. This way you can easily make your app tablet and phone friendly without torturing phone users with multiple activities.
Library comes with JavaDocs, multiple examples, in open source form, 2-clause BSD license and pre-ICS support (!). Pre-ICS devices are supported with the help of ActionBarSherlock
