Background location not tracking above android 11 device

Question

We cannot get latitude and longitude of location tracking. Please review the below code for background location tracking for android device. This same code is working in older android version. but the same code is not working for the latest android version 11. It returns null in android 11 device and above

private void fn_getlocation() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }

    locationManager = (LocationManager) getApplicationContext().getSystemService(LOCATION_SERVICE);
    isGPSEnable = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkEnable = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    if (!isGPSEnable && !isNetworkEnable) {

    } else {

        if (isNetworkEnable) {

            location = null;
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
 

              
                    return;
                }
 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 0, this);
          

            if (locationManager != null) {

                location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                if (location != null) {
                   
                    latitude = location.getLatitude();
                    longitude = location.getLongitude();

                    fn_update(location);
                }
            }

        }
        if (checkLocationPermission()) {

            if (isGPSEnable) {

                location = null;
               
                if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                    return;
                }
                
                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, this);
                if (locationManager != null) {
                    location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                    if (location != null) {
                      
                        latitude = location.getLatitude();
                        longitude = location.getLongitude();
                        fn_update(location);
                    }
                }
            }
        }


    }

}

manifest file:

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> <uses-permission android:name="android.hardware.location" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-feature android:name="android.hardware.location.gps" /> <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

From Android 11 onward, your app needs to request for the ACCESS_BACKGROUND_LOCATION permission.
