In this video it shows the steps for downloading an image file from AWS (Amazon Web Services) S3 (Amazon Simple Storage Service) in your Android App. It uses the signed URL of the file which is valid for a limited period (max 12 hours). In this demo the signed URL was generated with a validity of 1 hour post which the URL would expire. Signed URL is a publicly accessible URL for any resource on S3.
