i've been doing research on can't figure out. contacts in phone in sample app downloaded duplicated, so:
i'm quite sure has contactscontract.contacts. i've read on don't know how implement in code. (or indeed if there's way of doing it). want each contact listed once, not multiple time.
according http://developer.android.com/reference/android/provider/contactscontract.contacts.html :
contactscontract.contacts constants contacts table, contains record per aggregate of raw contacts representing same person. i have 3 java files in project, mainactivity, selectuser , selectuseradapter, believe mainactivity 1 pertaining problem. line :
phones = getcontentresolver().query(contactscontract.commondatakinds.phone.content_uri, null, null, null, contactscontract.commondatakinds.phone.display_name + " asc"); if need more code let me know.
here's mainactivity.java :
