从uri创建的文件不能被transferutility占用

Question

我正在尝试使用TransferUtility将文件上传到S3。我通过ACTION_OPEN_DOCUMENT目的获得Uri。我得到一个uri，从中创建一个文件。但是s3 transferutility给出了invalidArgumentsException

uri = resultData.getData();
File file = new File(uri.getPath());
final String split[] = file.getPath().split(":");
String file_path = split[1];
File fp = Environment.getExternalStorageDirectory();
File f = new File(fp,file_path);

AmazonS3 s3Client = new AmazonS3Client(new BasicAWSCredentials(my_access_id,my_secret_key));
s3Client.setRegion(Region.getRegion(Regions.US_EAST_1));
TransferUtility transferUtility = new TransferUtility(s3Client, getApplicationContext());
TransferObserver transferObserver = transferUtility.upload(bucket,"samp.png",f);
if (TransferState.COMPLETED == transferObserver.getState()) {
Toast.makeText(getApplicationContext(),"Transfer complete",Toast.LENGTH_SHORT).show();
                }

发生以下错误：
