title: about working with Fragment in Android 2.1 updated
body: <p>My first question I'd like to ask is that is it so that <strong>Fragment</strong> is only supported by <strong>android 3.0</strong> ? If I am developing <strong>Android 2.1</strong> application, can I use <strong>Fragment</strong>?</p>
  
  <p>My second question is, I am implementing <a href="https://stackoverflow.com/questions/6675747/how-to-inflate-a-activity-in-my-case">this</a> simple feature, <strong>Fragment</strong> is a good choice, but I am developing <strong>Android 2.1</strong> application, if the answer of my first question is negative, what could be the workaround to implement the feature I need?</p>
