Question

我们有几个广泛使用S3的Android应用。我们使用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”

我们尝试过使用0.1.0和0.2.1版本的SDK，两者都在大型（200MB +）上传时遇到同样的问题。

以下是我们的代码段：

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：

通过设置以下系统属性，使用S3时似乎可以解决很多这些SAX解析器错误。

System.setProperty（“org.xml.sax.driver”，“org.xmlpull.v1.sax2.Driver”）;
