Android SupportMapFragment inside Fragment

If you want to have map in fragment, you need to use MapView instead of SupportMapFragment How to use MapView in android using google map V2?

Works in 2017 (Kotlin):

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        val mapFragment = childFragmentManager.findFragmentById((R.id.map)) as SupportMapFragment
        mapFragment.getMapAsync(this)
    }
