android - Realm: Field Map inside another Map as RealmObject -

i need parse json incoming external system. here json example:

{     "address": "my address",     "contacts": "my contacts",     "exchangeratesmap": {         "chf": {             "field1": "7.103",             "field2": "11.003"          },         "eur": {             "field1": "90.123",             "field2": "1.003"         },         "usd": {             "field1": "0.103",             "field2": "20.123"          }     },     "name": "name of organization",     "id": 1 } 

as result create java pojo (not realm) in android application:

public class exchangerate {     private int id;         private string name;         private string address;         private string contacts;         private map<string, map<string, string>> exchangeratesmap = new hashmap<string, map<string, string>>();      } 

and work fine. ok.

and need migrate java pojo realm object.

question: how object exchangerates realmobject?

realm doesn't support maps yet (see https://github.com/realm/realm-java/issues/759), can convert list hand doing this:

public class exchangerateitem extends realmobject {     public string key;     public double field1;     public double field2; 

}

public class exchangerate {     private int id;     private string name;     private string address;     private string contacts;     private realmlist<exchangerateitem> exchangerates; } 

you need find way convert exchangerate blocks 1 object though. how depend on kind of json deserializer use or if use json directly.
