Answer 1

Since you are using nested fragments, you should use getChildFragmentManager()

SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);

And I recommend you to use getMapAsync method, because getMap is deprecated

mapFragment.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap googleMap) {
        setupMap(googleMap);
    }
});
