AWS Android SDK app for S3 Transfer Utility raises read exception

Question

I created an AWS S3 bucket. and I can access the bucket using https://github.com/awslabs/aws-sdk-android-samples/blob/master/S3TransferUtilitySample/S3TransferUtilityTutorial.md , TransferUtility SDK application is provided by Amazon.

I made some changes regarding the configuration of the corresponding region name and bucket, and then I was able to connect to S3.

I have the proper permission to read / write the S3 bucket, as granted to me by the server administrator. I successfully upload two images to an S3 bucket using code. Now I see two image files present in S3.

Now when I try to load this file, I get an exeception as

com.amazonaws.services.s3.model.AmazonS3Exception: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: 04800521FBB752B0)

I have read and write permissions, but I get this exception. This is only due to permission, or am I missing something.

Thanks in advance.

Answer 1

There was a problem with the previous conginto pool id, I think it had some permissions problems.

We changed the identifier of the cognito pool, and then it worked correctly.

Answer 2

I think there are other permissions to download. You need to establish who can download this file - reading is not enough. Right-click the file in your S3 bucket and check the permissions section - you will see it there.
