java - Realm query for latest record for each user -


how accomplish similar query in realm java 1 asked in question: how query sql latest record date each user cause seems realm lacks group method when fetching queries

here's realmobject:

public class memo extends realmobject {     @ignore     public static final int sent = 1;     @ignore     public static final int unread = 2;     @ignore     public static final int read = 3;     @ignore     public static final int pending = 4;     private static final string tag = memo.class.getname();     @primarykey     public string id = "";     @index     public string connection = "";     public string subject = "";     public string body = "";     public int status = 0;     public date date;     public boolean sentbyme = false;     public string remoteid = "";     public boolean isfile = false;     public string filepath = ""; }

this represents user:

public string connection 

realmresults<memo> latestmemos = realm.where(memo.class)                                       .findallsorted("date", sort.descending)                                       .distinct("connection");
