Shared Pref Data in App1 should fetch the latest data I,ve stored in other App?

Question

I have two apps, App1 and App2. I,m saving some data in App2 and accessing in App1. So when i,m coming back to App1 from App2 using backpress, shared pref data will not refresh that i,m accessing from App2. On removing App1 from background and coming back to same page will do the work.

So, what should I do such that, Shared Pref Data in App1 will fetch the latest data I,ve stored in App2 ?
