No option to get the URL of item in S3 bucket using key.

I have files(pictures) in my S3 bucket and I am displaying them on screen. I don’t want to use the Amplify.Storage.downloadFile(...) as it takes a lot of time to download and then render. I want to use a picture loading library like glide and to do that I need to get the URL of the picture (probably by using the key). Currently there is no such option in android.

But I think there should be a simpler way to do it in near future.

There will be! Please continue to follow our project for the upcoming changes and thank you for using Amplify 😃

Amplify Storage internally constructs a “service key”, which is a combination of StorageDownloadFileOptions, AWSMobileClient#getIdentityId(), and S3 key. This service key can be constructed using S3RequestUtils and be passed directly as a key along with the bucket name to generatePresignedUrl(). I imagine the sample code for temporary workaround would look like the following:

StorageDownloadFileOptions options = StorageDownloadFileOptions.defaultInstance(); // This is your download file options
String identityId = AWSMobileClient.getInstance().getIdentityId();
String serviceKey = S3RequestUtils.getServiceKey(
    options.getAccessLevel(),
    identityId,
    key,
    options.getTargetIdentityId()
);

AmazonS3Client s3 = Amplify.Storage.getEscapeHatch();
URL url = s3.generatePresignedUrl(
    bucketName, 
    serviceKey, 
    null
);
