Try this, it will worked. I used it for Hashtable.

public static Hashtable parseModifued(String json) {
    JsonObject object = (JsonObject) new com.google.gson.JsonParser().parse(json);
    Set> set = object.entrySet();
    Iterator> iterator = set.iterator();

    Hashtable map = new Hashtable();

    while (iterator.hasNext()) {
        Map.Entry entry = iterator.next();

        Integer key = Integer.parseInt(entry.getKey());
        KioskStatusResource value = new Gson().fromJson(entry.getValue(), KioskStatusResource.class);

        if (value != null) {
            map.put(key, value);
        }

    }
    return map;
}

Replace KioskStatusResource to your class and Integer to your key class.
