Use the below code- Function get Latitude, Longitude from Address- fun getLatLngFromAddress (context: Context, mAddress: String): String { val coder = Geocoder(context) lateinit var address: List<Address> try { address = coder.getFromLocationName(mAddress, 5 ) if (address == null ) { return "Fail to find Lat,Lng" } val location = address[ 0 ] return " Latitude: ${location.latitude}\n Longitude: ${location.longitude}" } catch (e: Exception...
