[jitsi-dev] contact-list with jitsi-android


hi ,
    I am trying to get the group and contactlist and show in a listview in CallContactFragment, i am trying to get rosters using:
but it won't work because the provider i got in CallContactFragment is the object of class->(ProtocolProviderService), it coudn't be tranformed to a (ProtocolProviderServiceJabberImpl)object, so i cann't use the method getConnection...
    Maybe it's not a good question, any clues?
