NullPointerException calling activity using DialogFragment

Question

I am in the process of converting my dialogs to DialogFragments. I\'m following the instructions here but it looks like they are using it in an Activity<

Answer 1

Shouldn't you use getSupportFragmentManager() and add (.add(fragment, tag)) the new instance of your fragment to the FragmentTransaction by doing .beginTransaction() and then call commit()? I guess thats what you are trying to do.

getActivity() returns null since your new Fragment instance is not attached to the Activity (native FragmentActivity/Activity or SherlockFragmentActivity/SherlockActivity, whatever it is).

Do some readings about using fragments. Instantiantion of the fragment is not enough. Find about underlying operations after instantiation.
