I have used the code below for uploading an image to the s3 bucket using Android.
AmazonS3 s3client = new AmazonS3Client(new BasicAWSCredentials(context.getString(R.string.accesskey),context.getString(R.string.secretkey)));
PutObjectResult result = s3client.putObject(new PutObjectRequest(bucketName, amazonfilepath, file).withAccessControlList(acl));
When I create bucket in Asia Pacific (Singapore) regions then it works fine. But I have to change regions of bucket to Asia Pacific (Mumbai) then it throws below error.
Amazon s3 image uploading:com.amazonaws.services.s3.model.AmazonS3Exception: The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256. (Service: Amazon S3; Status Code: 400; Error Code: InvalidRequest; Request ID: 85D0346520B14007), S3 Extended Request ID: gC67avqeowqS4+X+2qkBxzLxfj9ABVV22zWgPcm/rZBKC0RIso201+eMsvBsqdnH+8n0V9RI0J8=
I was used below SDK for same.
compile 'com.amazonaws:aws-android-sdk-s3:2.2.13'
now used below version of sdk than it will work fine.
compile 'com.amazonaws:aws-android-sdk-s3:2.4.0'
Confirmed, Updating the sdk to latest version fixed it. in my case,
implementation 'com.amazonaws:aws-android-sdk-core:2.6.13'
implementation 'com.amazonaws:aws-android-sdk-s3:2.6.13'
if you have the same issue, check the aws sdk version in your app level build.gradle file.
Just answering incase someone comes here searching for it.
