How to create a fully unclosable ProgressDialog?

Question

How to show a ProgressDialog from a background service that is unclosable in any way, displayed above whole screen, above any app, including keys? I mean a dialog exactly like the "Power off.. shutting down" one that is displayed when phone is shutting down, when you can neither do anything to make it disappear nor click anything below it.

PS. If the app needs to be a system app to create such dialog, that's not a problem for me.

I've just found this, I'm trying to use it somehow https://developer.android.com/work/cosu.html — Nicofisi, Apr 05 '17 at 16:19

progressdialog from a service? – Simo Apr 05 '17 at 16:04
I'd be able to close this by using the back, home or app list button – Nicofisi Apr 05 '17 at 16:07
