How to Fetch the Background Location In Fragment in Android 11 in Kotlin?

Question

It will be a great help if someone can give a bit working demonstration with proper code. I want to fetch the background location every 2-3 minutes.

I have tried this below code, but it is showing toast message Permission Denied every time.

I have written this code inside a fragment,I have tried to search on medium, other sites, and youtube, all are showing the demonstration for foreground location,please help me.

 private var mFusedLocationClient: FusedLocationProviderClient? = null
    override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            mFusedLocationClient=LocationServices.getFusedLocationProviderClient(requireContext())

        if(ActivityCompat.checkSelfPermission(requireContext(),Manifest.permission.ACCESS_BACKGROUND_LOCATION)==PackageManager.PERMISSION_GRANTED)
        {
            Toast.makeText(requireContext(),"IF",Toast.LENGTH_SHORT).show()
            getTheCurrentLocation()
        }
        else
        {
            Toast.makeText(requireContext(),"Else",Toast.LENGTH_SHORT).show()
            requestPermissions(arrayOf(Manifest.permission.ACCESS_BACKGROUND_LOCATION)
                ,100)
        }
    }

    override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        if(requestCode==100 && grantResults.size>0 && (grantResults[0]==PackageManager.PERMISSION_GRANTED))
            getTheCurrentLocation()
        else
        {
            Toast.makeText(requireContext(),"Permission Denied",Toast.LENGTH_SHORT).show()
        }
    }

    private fun getTheCurrentLocation()
    {
        Toast.makeText(requireContext(),"In GetCurrentLocation Fun",Toast.LENGTH_SHORT).show()
       var locationManager:LocationManager?=null
        locationManager = requireActivity().getSystemService(Context.LOCATION_SERVICE) as LocationManager

        if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
        {
            //when location service is enabled
            //Get the last location
            if (ActivityCompat.checkSelfPermission(
                    requireContext(),
                    Manifest.permission.ACCESS_FINE_LOCATION
                ) != PackageManager.PERMISSION_GRANTED
                ) {
                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // here to request the missing permissions, and then overriding
                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                //                                          int[] grantResults)
                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.
                return
            }
            mFusedLocationClient?.lastLocation?.addOnCompleteListener(OnCompleteListener {
               var location:android.location.Location?=null

                {

                   var locationRequest:LocationRequest=LocationRequest().
                       setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                       .setInterval(1000)
                       .setFastestInterval(100)
                       .setNumUpdates(1)

                     var locationCallback:LocationCallback=object:LocationCallback()

                        Looper.myLooper())
                }

            })
        }
    }
