i want search contact list particular contact using _id or lookup_key. 1 of these 2 better , reason. helpful if give main differences of both. android doc says- _id - row id. consider using lookup_key instead. lookup_key - opaque value contains hints on how find contact if row id changed result of sync or aggregation. so when in case contacts rowid change reason lookup_key our way go. check this link on how find not there on docs guess.
