AWS Amplify. Use existing resources

I have followed the tutorial:

https://aws-amplify.github.io/docs/android/start?ref=amplify-android-btn

To integrate AWS S3 with my android application.

I'm able to download a file, and everything works fine.

I've notice that when i create a enviroment, it creates a new bucket, i don't want to create a new bucket, i want to use an existing one.

I've tried to change the bucket in the awsconfiguration.json. But it does not work.

"S3TransferUtility": {
    "Default": {
        "Bucket": "somebucket",
        "Region": "us-east-1"
    }
}

AmazonS3Exception: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: <ID>)

I don't want to create a new bucket, i want to be able to access crated buckets that share objects across other apps.

I solved. For anyone who is interested in.

For using an existing bucket, without creating a environment with amplify. The only thing i done was to add manually the file awsconfiguration.json inside the raw folder. I do not use amplify.

So, my awsconfiguration.json looks like:

{
"Version": "1.0",
"IdentityManager": {
    "Default": {}
},
"CredentialsProvider": {
    "CognitoIdentity": {
        "Default": {
            "PoolId": "cognito-pool-id",
            "Region": "region"
        }
    }
},
"S3TransferUtility": {
    "Default": {
        "Bucket": "somebucket",
        "Region": "region"
    }
}
}

And to download objects from S3 i make my TransferUtility like this:

val transferUtility = TransferUtility.builder()
        .context(context)
        .awsConfiguration(AWSMobileClient.getInstance().configuration)
        .s3Client(getAmazonS3Client())
        .build()

private fun getAmazonS3Client(): AmazonS3Client{
    if (amazonS3Client == null) {
        amazonS3Client = AmazonS3Client(
                CognitoCachingCredentialsProvider(
                    context, 
                    BuildConfig.S3_POOL_ID, 
                    Regions.US_EAST_2
                ),
                Region.getRegion(Regions.US_EAST_2)
                )
    }

    return amazonS3Client!!
}
