Consequences of isRouteDisplayed() on map view

I'm just wondering what consequences 开发者_Go百科the method

isRouteDisplayed()

has, regarding to functionality of a map view...

I have two activities, one displays a route and one doesn't. Is it mandatory to let the first isRouteDisplayed()-Method return true? What effects does it have?

greets, poeschlorn

From the docs:

For accounting purposes, the server needs to know whether or not you are currently displaying any kind of route information, such as a set of driving directions. Subclasses must implement this method to truthfully report this information, or be in violation of our terms of use.
