低连接上的领域对象服务器同步。

Question

我有一个领域对象服务器，并尝试与 Android 设备同步数据，例如：

SyncCredentials syncCred = SyncCredentials
            .usernamePassword(username, password, false);
SyncUser.loginAsync(syncCred, url, new SyncUser.Callback() {
        @Override
        public void onSuccess(SyncUser user) {
        ...some code...
        }

        @Override
        public void onError(ObjectServerError error) {}

它与wi-fi 一起工作得很好，但在互联网连接较低的情况下（例如为模拟器设置GSM 网络类型）我得到一个错误（onError (ObjectServerError error) 调用）：

是否可以通过低 Internet 连接来同步数据？
