Realm.io与改造

Question

我试图将我的改装对象存储在Realm.io db中。我已经关注了代码段here，但仍有问题。对此的任何帮助都将非常感激。

我的代码是

自定义GSON解析器

import com.google.gson.ExclusionStrategy;
import com.google.gson.FieldAttributes;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

import io.realm.RealmObject;

public class CustomGsonParser {

    public static Gson returnCustomParser(){
        Gson gson = new GsonBuilder()
                .setExclusionStrategies(new ExclusionStrategy() {
                    @Override
                    public boolean shouldSkipField(FieldAttributes f) {
                        return f.getDeclaringClass().equals(RealmObject.class);
                    }

                    @Override
                    public boolean shouldSkipClass(Class<?> clazz) {
                        return false;
                    }
                })
                .create();
        return gson;
    }
}

领域呼叫

private void requestData(){
    RestAdapter adapter = new RestAdapter.Builder()
            .setEndpoint(getResources().getString(R.string.app_url))
            .setLogLevel(RestAdapter.LogLevel.FULL)
            .setConverter(new GsonConverter(CustomGsonParser.returnCustomParser()))
            .build();

    BackendAPI api = adapter.create(BackendAPI.class);

    api.getColleges(new Callback<List<College>>() {
        @Override
        public void success(List<College> colleges, Response response) {
            mItems = colleges.toArray(new College[colleges.size()]);

            realm.beginTransaction();
            List<College> realmObjects = realm.copyToRealmOrUpdate(colleges);
            realm.commitTransaction();
        }


        @Override
        public void failure(RetrofitError error) {
            System.out.println(error);
        }
    });

和对象，我省略了setter和getter方法

import java.util.List;
import io.realm.RealmObject;
import io.realm.annotations.Ignore;

public class College extends RealmObject{
    private String name;
    private String shortName;
    private String mainColor;
    private String secondaryColor;
    private Boolean enabled;
    private float latitude;
    private float longitude;
    private int id;
