旧的SDK的AVFILE部分都不能用 换上最新的但是一运行就报错 unity4.6.9版本

AVFILE的上传是不是有问题
byte[] data = System.Text.Encoding.UTF8.GetBytes("LeanCloud is a great cloud service!");
AVFile file = new AVFile("mytxtFile.txt", data,);
file.SaveAsync();
这种情况下是上传成功而且后台有数据
AVFile file = AVFile.CreateFileWithLocalPath("files.txt", Path.Combine(Application.streamingAssetsPath, "files.txt"));
file.SaveAsync()；
这种情况出现上传成功 但是后台没有数据
