[FIXED] Location not working after activate via code Android

Issue

i have an issue. My app has required location service, so i run the code above to show a dialog to the user and if the user clicks "OK" I activate the location and save the event.

Code to check and show the dialog if the location is deactivated:

private void createLocationRequest() {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(10000);
    mLocationRequest.setFastestInterval(5000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

}

private void askForLocationChange() {
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(mLocationRequest);
    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());

    task.addOnSuccessListener(new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            getLastKnownLocation(); //Works fine
        }
    });

    task.addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            //Shows the dialog
            if (e instanceof ResolvableApiException) {
                try {
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException ignored) {
                }
            }
        }
    });
}

@EDIT I changed a little and it works pretty well... if location is activated previously...

I'm using a listener and get the location only in the onLocationChanged function... but if the location is deactivated, after active (above code), the location has a delay very large, what google uses on the google maps? because if u enter google maps with the location off, and active it, the location is show on the map after a few seconds.

Solution

I have used the same listener, if the user activates the location i create the listener and remove it before i get the location on the onLocationChange method, because sometimes it takes around 10 seconds to get the user location.

@Override
public void onLocationChanged(@NonNull Location location) {
        //Save Event

        stopUsingGPS();

    }

public void stopUsingGPS(){
    if(locationManager != null){
        locationManager.removeUpdates(GPSTracker.this);
    }
}

And after i get the location i remove the listener.
