android - AVFile是否支持上传网络文件？
看到Android SDK里有AVFile(java.lang.String name, java.lang.String url)，但在doc中没有任何说明，url参数是指文件的URL路径吗？试了一下直接通过AVFile.saveInBackground()上传图片，报了如下错误：

请问是不是暂时没有这样的功能？我的调用代码很简单：
AVFile image = new AVFile("test.jpg", "http://img3.douban.com/icon/u81973751-1.jpg");
image.saveInBackground();
