I am converting my app to use the v4 compatibility package and fragments. I have done well so far, but I need to launch a DialogFragment from a preference click in a PreferenceActivity. Since there isn't a PreferenceFragment in the compatibility library, I'm stuck with using PreferenceActivity. Is it possible to get a reference to the fragment manager and call the DialogFragment or do I just have to continue using the old dialog if I need a dialog from a preference?

To create a DialogFragment , first create a class that extends DialogFragment , and override onCreateDialog() , as shown in the following example. Similar to how onCreateView() should create a root View in an ordinary fragment, onCreateDialog() should create a Dialog to display as part of the DialogFragment .
Dialog: A dialog is a small window that prompts the user to make a decision or enter additional information. DialogFragment: A DialogFragment is a special fragment subclass that is designed for creating and hosting dialogs.
Android DialogFragments. DialogFragment is a utility class which extends the Fragment class. It is a part of the v4 support library and is used to display an overlay modal window within an activity that floats on top of the rest of the content. Essentially a DialogFragment displays a Dialog but inside a Fragment.
tl;dr: The correct way to close a DialogFragment is to use dismiss() directly on the DialogFragment.
Not without jumping through hoops.
You could make a very simple activity with the sole purpose of launching the DialogFragment. If you do this you will need to finish() that activity when the DialogFragment dialog has been dismissed.
