showNow
Display the dialog, immediately adding the fragment to the given FragmentManager. This is a convenience for explicitly creating a transaction, adding the fragment to it with the given tag, and calling commitNow. This does not add the transaction to the fragment back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.
Parameters
manager
The FragmentManager this fragment will be added to.
tag
The tag for this fragment, as per FragmentTransaction.add.
