6. Getting last user’s
   location
   //Manifest.permission.ACCESS_FINE_LOCATION
   
   
   private val client =
   
   
   LocationServices.getFusedLocationProviderClient(
   
   
   activity
   
   
   )
   
   
   client.lastLocation.addOnSuccessListener {
   
   
   location
   -> . ..
   
   }

7. Getting updates
   on user’s location
   private val locationCallback =
   
   
   object : LocationCallback() {
   
   
   override fun onLocationResult(r: LocationResult) {
   
   
   //
