FusedLocationClient not calling onLocationResult

Before requesting location updates, your app must connect to location services and make a location request. Some thing like this:

private static LocationRequest createLocationRequest() {
    LogHelper.trace("createLocationRequest");
    LocationRequest mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(200000);
    mLocationRequest.setFastestInterval(300000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    return mLocationRequest;
}

public static void checkLocationService(final Fragment fragment, final FusedLocationProviderClient client, final OnSuccessListener<LocationSettingsResponse> successListener, OnFailureListener failureListener) {

    LogHelper.trace("checkLocationService");
    final LocationRequest request = createLocationRequest();
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(request);

    SettingsClient settingsClient = LocationServices.getSettingsClient(fragment.getActivity());
    Task<LocationSettingsResponse> task = settingsClient.checkLocationSettings(builder.build());

    task.addOnSuccessListener(fragment.getActivity(), new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            LogHelper.trace("onSuccess");
            startLocationService(client, request, new LocationCallback());
            successListener.onSuccess(locationSettingsResponse);
        }
    });

    task.addOnFailureListener(fragment.getActivity(), failureListener);
}

try to active/desactive location from android settings.
