This page explains best practices for cleaning up instances after they are no longer needed.
Use Navigator#clearDestinations
and Navigator#cleanup
when navigation sessions are completed
To prevent memory leaks and ensure proper cleanup, use
Navigator#clearDestinations
and Navigator#cleanup
after the navigation
session is completed and the Navigator instance is no longer needed. This can be
done when the user has navigated away from the map and when onDestroy()
of the
associated activity is invoked.
Clean up GoogleMap
elements when they are no longer needed
If your app uses a GoogleMap
instance for non-navigation maps experiences, be
sure to clean up this instance when it is no longer needed. For example, clean
up the Polygon, Polyline, and Marker elements associated with GoogleMap
by
calling the Polygon#remove
, Polyline#remove
, and Marker#remove
methods,
respectively. Then, to free up the GoogleMap
instance after it is not longer
needed, call GoogleMap#clear
assign the instance to null
.

instance in your app, see

interaction best
practices.
