### Question:
Api { @NonNull @WorkerThread public CallResult<List<ActiveOrder>> getActiveOrders() { JsonObject response = authApi.makeRequest(AuthApi.TradeMethod.ACTIVE_ORDERS, null); CallResult<List<ActiveOrder>> result = new CallResult<>(); if (response == null || (response.has(SUCCESS_KEY) && response.get(SUCCESS_KEY).getAsInt() == 0)) { result.isSuccess = false; result.error = response == null ? generalErrorText : response.get(ERROR_KEY).getAsString(); return result; } result.isSuccess = true; List<ActiveOrder> activeOrders = new ArrayList<>(); Set<String> orderIds = response.getAsJsonObject(RETURN_KEY).keySet(); for (String item : orderIds) { long orderId = Long.parseLong(item); activeOrders.add(ActiveOrder.create(orderId, response.getAsJsonObject(RETURN_KEY).getAsJsonObject(item))); } result.payload = activeOrders; return result; } Api(@NonNull Context appContext, @NonNull String hostUrl,
