Use S3 TransferUtility with Content Uri

Question

im trying to upload a file to S3 using the TransferUtility. I get the Uri via the ACTION_GET_CONTENT Intent. The Result of the Intent looks something like content://com.android.externalstorage.documents/document/0000-0000:DCIM/Camera/20170811_105420_HDR.jpg

I managed to Upload the File via a AmazonS3Client using PutObjectRequest and InputStream but I'd like to use TransferUtility and the TransferObserver for convenience and the ability to pause the upload.

My Code:

TransferUtility tU = TransferUtility.builder()
    .context(mActivity.getApplicationContext())
    .awsConfiguration(AWSMobileClient.getInstance().getConfiguration())
    .s3Client(new AmazonS3Client(AWSMobileClient.getInstance().getCredentialsProvider()))
    .build();

File f = new File(_uri.getPath());
TransferObserver tO = tU.upload("test.jpg", f);

crashes with:

Caused by: java.lang.IllegalArgumentException: Invalid file: /document/0000-0000:DCIM/Camera/20170811_105420_HDR.jpg

File f = new File(_uri.getPath());

A Uri is not a file, and TransferUtility seems to demand a file. So, either:

• Stop using ACTION_GET_CONTENT, and instead integrate a file chooser library, so you can limit yourself to actual files, or

• Use the Uri and openInputStream() on ContentResolver, then use that stream to make a copy of the data to some file that you control, then upload that file.
