Android contact info update with intent?

阅读更多关于 Android contact info update with intent?

I can create new contact with Intent by passing info as extra data with putExtra, is it possible to create Intent with info and if contact is already in phonebook it will be update with new info? Actually you can use intents to create new contacts with ContactsContract and it's not deprecated. http://developer.android.com/reference/android/provider/ContactsContract.Intents.Insert.html example that works for me: Intent i = new Intent(Intent.ACTION_INSERT_OR_EDIT); i.setType(ContactsContract.Contacts.CONTENT_ITEM_TYPE); i.putExtra(Insert.NAME, "TESTTEST"); i.putExtra(Insert.PHONE, "209384");
