Make my XMPP gateway accounts (for MSN,AOL,ICQ,..) connection invisible


I am using Smack API version 2.2.1

I couldn’'t find a way to not show the Toaster popup for the roaster of my register XMPP accounts?

I would like make my XMPP gateway accounts (for MSN,AOL,ICQ,…) connection invisible ?

Any help would be kindly appreciated.

Best whises.
