Stop Location Listener in Android

Question

In my android app I need to get current GPS location of the user at the start of the application only if location has change from the previous location. But the problem is when I inside the application if location change (ie If user was traveling while using the app) app is starting from the beginning.

I need to stop location listener after getting user current location. removeUpdates method didn't work for me.

Please help me on this issue. thanks in advance !

removeUpdates is the way to go, can you show some code as to why it did not work. – Bathe

Answer 1

mLocManager.removeUpdates(locationListenerObject);
mLocManager = null;

Call this inside your onLocationChange Method when lat and long has been captured by the listener.

Hope I helped..

It might take some time for the onLocationChange method to be called. Around 1 sec might be. Right? – Discus

thx this works. the weird thing is that the .removeUpdates() wants us to ask for permissions! – Cookout

Answer 2

You can stop the LocationListener by making its object to null after stoping LocationListener locationManager.removeUpdates(mLocListener);, that is mLocListener = null; when you want it to stop fetching the Latitudes and Longitudes.

Reflect

I just tried this on a actual device and it does not remove the listening for updates – Cookout

Out of curiosity, why is setting the listener to null necessary if we already called removeUpdates(locationListener l)? – Batson

Answer 3

You can stop continuous location updating by calling method locationManager.removeUpdates(locationListener).

Here is an example :

LocationManager locationManager; 
LocationListener locationListener;

// for location updates 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

// stop location updating
locationManager.removeUpdates(locationListener);

Answer 4

locationManager.requestSingleUpdate(String provider, LocationListener listener, Looper looper);

If you only need to get the current location once, try this method instead using

locationManager.requestLocationUpdates(String provider, long minTimeMs, float minDistanceM, LocationListener listener)

and stop the update using locationManager.removeUpdates(LocationListener listener)

hope this works and help others with same problem.

Try This

locationManager = activity!!.getSystemService(Context.LOCATION_SERVICE) as LocationManager

locationListener = object : LocationListener {
            override fun onLocationChanged(location: Location) {
                if (location != null) {
                    Log.e(
                        "LOCATION",
                        "Latitude " + location.latitude.toString() + "  | Longitude :" + location.longitude.toString()
                    )
                    if (locationListener != null)
                        locationManager!!.removeUpdates(locationListener!!)
                }
                //Toast.makeText(getApplicationContext(),location.toString(),Toast.LENGTH_SHORT).show();
            }

            override fun onStatusChanged(provider: String, status: Int, extras: Bundle) {
            }

            override fun onProviderEnabled(provider: String) {
            }

            override fun onProviderDisabled(provider: String) {
            }
        }
