【问题描述】：
我们有几个广泛使用 S3 的 Android 应用。我们正在使用 Android SDK 中的 TranferManager 类将文件上传到 S3。它说：“E/HttpClient(6081): com.amazonaws.AmazonClientException: 无法初始化 XMLReader 的 sax 驱动程序”
我们已尝试使用 SDK 的 0.1.0 和 0.2.1 版本，但在大型 (200MB+) 上传时都会出现相同的问题。
下面是我们的代码sn-p：
ObjectMetadata attMetaData = new ObjectMetadata();
attMetaData.setContentLength(attachment.getFileSize());
TransferManager tm = new TransferManager(Utility.getInstance().getAWSInstance(OutboxService.this));
Transfer myUpload = tm.upload(Constants.S3.BUCKET, Attachment.mediaFolders.get(attachment.getFileType())+ attachment.getFileName(), is, attMetaData);
异常日志是：
