Why might MapView not respond to marker updates?

Question

Java

Hello.
A strange bug has come out - if the application has been minimized for a long time, then after it is expanded, MapView does not react to updating markers in any way (for example, if the set of markers has changed).
Moreover, if it was curtailed for a short time - everything works in the normal mode.
I suspect that the matter is in some features of the MapView life cycle, tk. manually calling mvMap.invalidate() did nothing.
What do you advise?

Most likely, you lose the marker objects, so you can neither delete nor update them. Explicitly clear the map in onPause() and restore its state in onResume().
