App run in background?

Is there a way to have my Android/IOS game always run in the background? It’s a clicker and uses an idle counter. I’d like users to not need to leave the app open in order to collect things.

I know how to use notifications, but how would that make the app run in the background? Is it even possible?

you are really new to UE4 you asked like 3 questions but there isnt acctuly any way to do it without a notification to be all the time on the phone and i dont think thats nice

not in UE4

Onesignal.com exist for that . Its a push notification
