import   import android support v4 app FragmentActivity  import android support v4 app FragmentManager

Instead of  extends Fragment   use  extends android support v4 app Fragment    This works for me  for  API14 and above

Your activity doesn t extend FragmentActivity from the support library  therefore the method is not present in the superclass  If you are targeting api 11 or above  you could use Activity getFragmentManager instead
