title: Fragment or Support Fragment?
body: <p>I am developing an app that supports Android >= 4.0. It uses fragments from the <code>android.app</code> package. As I am facing problems with the older fragment implementation in 4.0, like <a href="https://stackoverflow.com/questions/13540712/app-crashes-on-super-onsaveinstancestate">this one</a>, that are already fixed in the support library, I am considering switching back to the fragment implementation from the support library to get a more reliable and consistent implementation.</p>
  
  <p>What is your opinion on this? Are you using fragments from the support library, even though they are already available, when developing for Android 4?</p>
