当使用S3进行身份验证来自服务器端时，如何从android（客户端）调用AWS S3映像URL（php + aws sdk php v3）

Question

I have android as front-end, (php,mysql) as back-end and AWS as the infrastructure host. I am developing APIs using laravel to be consumed by the android app but having problem figuring out how to display images hosted on S3 in android.
I am able to fetch (private)resource URL from S3 using the AWS PHP SDK's getObjectURL method but I can't pass the URL alone as an image src in Android as the URL does not contain credentials and authentication is only happening from server side.
Should I first download images from S3 to my server, cache it and serve to Android or is there a way I can have android directly access the images from the URL i.e. can i append credentials with URL?

You can directly access images from s3 bucket using Andriod SDK see this : https://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/s3transferutility.html
