I’m sorry if the question is not understood correctly.
This is my case:
I have a back-end service with an API that returns a json object as usual. Also I have a mobile application that consumes that API, the response of one of the calls is a json that can contain several images url. my mobile application after getting the response from the API, download each image. These can be a lot of images to download, that is, many requests to the server for those images. What is the best thing to do, how can you manage these multiple downloads, is there a method, is there a technology, what is the best approach?
I guess it has been understood.
