Smack 4.4.0: Roster class #getInstaceFor() method uses XMPPConnection, an interface class as passing parameter

[cmeng]

In Roster class the method: public static synchronized Roster getInstanceFor(XMPPConnection connection) defines XMPPConnection interface class as its passing parameter.

This is flagged as error when a calling routine uses an interface class as passing parameter in Roster.getInstanceFor().

I am sorry, I have a hard time figuring out this issue report.

Yes, Roster.getInstanceFor() declares an interface type as its sole paramater, as do most getInstanceFor() methods in Smack.

@cmeng

This is flagged as error

Flagged where? By whom? Could you show us the text of the error?

“interface class”?

My apology, I think it is my mistake.
Last week, android studio flagged this as error in aTalk source; However I just recheck again, seem it is no more flagged as error.
Sorry for inconvenience cause to everybody.
