Okay. I've read that in a few places, but never anything that seemed quite clear and authoritative enough to really trust it. For instance Google's docs [1] say:

    In addition to the $200 monthly free credit, all users get:
      
      Free Maps usage for iOS, Android, and Embed
      (for displaying maps only)

But in a section about Dynamic Maps and Street View they also say:

    This change affects the following Google Maps Platform APIs:
    Maps JavaScript API, Maps Static API, Street View API, Maps
    SDK for Android, and Maps SDK for iOS.

So are maps on Android only free if the user can't interact with them?
