Missing method on Smack 4.4.6

I’m working to integrate XMPP-based chat into our Android app. For starting point, we use Influence (which uses Smack). So far it works OK.

It doesn’t have OMEMO encryption enabled, though. The doc says:

//set path in case we want to use a file-based store (default)
OmemoConfiguration.setFileBasedOmemoStoreDefaultPath(new File("path/to/your/store"));

BTW, I’m using Smack 4.4.6 and Android Studio complained that it couldn’t find

OmemoConfiguration.setFileBasedOmemoStoreDefaultPath()

So what’s the replacement?
