java.lang.IllegalArgumentException：JSON对象没有主键字段“ id”

Question

I use realm to parse this JSON, but I get this error: java.lang.IllegalArgumentException: JSON object doesn't have the primary key field 'id'.

LINK of Json

this is my method :

    Realm r = Realm.getDefaultInstance();
        r.beginTransaction();
        r.createOrUpdateObjectFromJson(Application.class,result);
        r.commitTransaction();

my Application class is :

public class Application extends RealmObject {

    @PrimaryKey
    private int id;
    private RealmList<girl> girls;


    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public RealmList<girl> getGirls() {
        return girls;
    }

    public void setGirls(RealmList<girl> girls) {
        this.girls = girls;
    }

    public Application() {
    }

    public Application(int id, RealmList<girl> girls) {
        this.id = id;
        this.girls = girls;
    }
}

my class girl is

public class girl extends RealmObject {

    @PrimaryKey
    private int id;
    private String name;
    private String ville;
    private String tel;
    private String photo;
         //getters and setters and constructors with and without params
}
