you can use now FragmentCompat for this purpose in a fragment
http://developer.android.com/reference/android/support/v13/app/FragmentCompat.html

@pantos27 FragmentCompat does not have support for v4.Fragment. Do you have any code for using FragmentCompat ?

Hi, thank you for the code.
Would be also helpful the gist with example how to use it in main activity for example.
