MapSettings v MockSettings Persistence

[johnnymoralez]

Context: Android Tests for App Lifecycle Callbacks and Checking for updates

TLDR - Can I still use MapSettings to persistent Settings like MockSettings did in previous versions or should I move to something else?

I'm moving from 0.6.2 to 1.0.0 and see that MockSettings has changed to MapSettings. I have some tests that are now failing and I'm trying to figure out how to move forward.

MockSettings used to persist the data I'm testing, i.e. app version has been updated. However, using MapSettings, I see when I go to check the app version the second time around, it's null instead of version one.
