What should be the reaction of the application to such an action?

Question

Android

I made a splash screen in the application. In this activity, I go to the internet to get information from 30 pages and download 30 small pictures. The activity screen displays information that data is being downloaded. If the user minimizes the application during the download, the download will continue. Should this action be handled, like pause the download and then resume, or let it load in the background? Or how do normal, experienced people do it?
Additional information:
In general, such an operation does not occur every day and not every time, but approximately 1 time in 2 days. Download duration 30 sec on wifi internet.

Answer 1

It is better if you pause the download when you minimize the application.
If the user returns to the application, download further.
If closed - we are content with what was downloaded.
At the next startup - check the relevance and download only new ones.
