    MarkerViewManager markerViewManager = new MarkerViewManager((ViewGroup) findViewById(R.id.markerViewContainer));
    IconManager iconManager = new IconManager(nativeMapView);
    Annotations annotations = new AnnotationContainer(nativeMapView, annotationsArray);

when I break, I find nativeMapView object is null. Why and what I shuld solve with it ???

@hw118118 could you add the code from When I click a button, the map will load in a fragment. Without that information it will be hard to reproduce the same scenario. Thank you.

Maybe it's related but I'm using MapBox with its SupportMapManager within a viewPager and I get NPE on nativeMapView.destroy() ( @mapView.onDestroy() ) if I switch between the fragments in the viewPager.
Crash happening after updating from 5.1.5 to 5.2.0

@sictiru not related, fixed with #10589. Planning to ship that in a 5.2.1 patch release today.
