API Map Google Maps does not Render on mobile, only in Android Studio

I'm learning Android alone, over the internet and I'm working this time with the Google Maps API. I've done several things with it in Android Studio, displaying, using marker, geolocation, among other functions. But when I did the APK yesterday and rode the NOX virtual machine or mobile phones, the API map is not rendering. It runs the application, does the application's functions, just does not render the map.

Forexample,inthisapplicationbelow,whenyouclickonthemap(evenifitisnotrendered)itdisplaysthelocationdata(country,neighborhood,city,etc.)onthescreen.

ps:Hegivesnoerroratallinnotime.Onlythemapdoesnotrenderonthephone.AndroidStudioworksnormally.
