title: FragmentActivity vs managing Fragment using FragmentTransaction?
body: <p>many tutorials on <code>Fragment</code> found on the web (like <a href="http://android-developers.blogspot.com.es/2011/02/android-30-fragments-api.html" rel="nofollow">this one</a>) use <code>FragmentActivity</code>. It seems to be the static way of using <code>Fragment</code>, as opposed to the dynamic way using <code>FragmentTransaction</code> to load <code>Fragment</code> s in a container in a normal <code>Activity</code>.</p>
  
  <p>I'm using API 12 and <code>FragmentActivity</code> is not there (it's in <code>android.support.v4.app</code>).</p>
  
  <p>So if I don't use the Android support package, I can only manage <code>Fragment</code> dynamically, right? Why has <code>FragmentActivity</code> disappeared?</p>
  
  <p>Thanks</p>
