[hho]

You can get rid of the !! on the fragment:

progressDialogFragment?.let {
  if (!it.isAdded) it.show(fragmentManager!!, TAG_PROGRESS_DIALOG)
}

Notice however, that this doesn't throw if the fragment is not initialized (you could add a ?: error("not initialized") or similar at the end though)
