A ListFragment Application in Android

In this article we will create an application which displays a list of countries using ListFragment. ListFragment is a subclass of Fragment class which can display a set of items in a listview and facilitates to exist as a fragment. We are building this application for Android 4.0 in which fragments are supported by default.
