title: Android - Activity vs FragmentActivity?
body: <p>I am new in Android. I want to build an app with tab format. I found many documentation where <code>Activity</code> has been used. Also in many cases have used <code>FragmentActivity</code>. I am not sure which will be better to start. Please suggest me should I use <code>Activity</code> or <code>FragmentActivity</code> to start development in tab format?</p>
