Show physical address in Google Maps API

Using the same function:

private fun getAddress(lat: LatLng): String? {
        val geocoder = Geocoder(this)
        val list = geocoder.getFromLocation(lat.latitude, lat.longitude,1)
        return list[0].getAddressLine(0)
    }

I’ve solved. Only I converted the objetcs to LatLng data. and I encapsulated to my mapOnReady

If anyone has the same issue this is my mapOnReady code:

mMap.setOnMapLongClickListener { latlng →
//mMap.clear(); -Let only one marker
mMap.animateCamera(CameraUpdateFactory.newLatLng(latlng))
//mMap.setOnInfoWindowClickListener()
getcoordinates = LatLng(latlng.latitude, latlng.longitude) //catch coordinates from maps API

        val markerOptions = MarkerOptions().position(getcoordinates)
        /*val titlesr = getAddress(getcoordinates)
        markerOptions.title(titlesr)*/
        val titlesr = getAddress(getcoordinates)
        markerOptions.title(titlesr)

        //.title(mMap.addMarker(markerOptions).toString()))
        mMap.addMarker(MarkerOptions()
            .position(getcoordinates)
            //.title(getcoordinates.toString()) -->ONLY SHOW THE LATITUDE AND LONGITUDE
            .title(getAddress(getcoordinates))
            .snippet("La ubicación puede ser precisa más no exacta."))
        //.title("Hola") --Basic marker interaction with user
    }

And put correctly the objects with correct encapsulation, and declaration on each other.

Thank you.
