FusedLocationProviderClient takes up to 30 seconds to retrieve first location updates

Question

When I first boot my app, it takes FusedLocationProviderClient up to 30 seconds to start providing location updates (i.e. up to 30 seconds before the blue dot shows up). I have a FusedLocationProvider that encapsulated in a LiveData as seen below and I'm trying to figure out what's wrong but can't.

public class LocationLiveData extends LiveData<Location> {

    private final static int LOCATION_REQUEST_INTERVAL_SECONDS = 5;
    private final static int MIN_DISPLACEMENT_REQUEST_METRES = 0;
    private final String TAG = this.getClass().getName();

    private final Context context;

    private FusedLocationProviderClient fusedLocationProviderClient = null;
    private LocationCallback locationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            setValue(locationResult.getLastLocation());
        }
    };

    public LocationLiveData(Context context) {
        this.context = context;
    }

    @Override
    protected void onActive() {
        super.onActive();
        FusedLocationProviderClient locationProviderClient = getFusedLocationProviderClient();
        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        locationRequest.setInterval(TimeUnit.SECONDS.toMillis(LOCATION_REQUEST_INTERVAL_SECONDS));
        locationRequest.setSmallestDisplacement(MIN_DISPLACEMENT_REQUEST_METRES);
        locationProviderClient.requestLocationUpdates(locationRequest, locationCallback, null);
        Log.d(TAG, "Getting location...");
    }

    @NonNull
    private FusedLocationProviderClient getFusedLocationProviderClient() {
        if (fusedLocationProviderClient == null) {
            fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(context);
        }
        return fusedLocationProviderClient;
    }

    @Override
    protected void onInactive() {
        if (fusedLocationProviderClient != null) {
            fusedLocationProviderClient.removeLocationUpdates(locationCallback);
        }
    }
}

Here is my fragment that holds another MapFragment and calls getMapAsync() on it. Here is the pertaining code:

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup viewGroup, Bundle bundle) {
        mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_map, viewGroup, false);

        mBinding.setView(this);

        mBinding.setViewModel(ViewModelProviders.of(this).get(MapsViewModel.class));

        FragmentManager fragmentManager = getChildFragmentManager();
        SupportMapFragment mapFragment = (SupportMapFragment) fragmentManager
                .findFragmentById(R.id.map_fragment);
        mapFragment.getMapAsync(this);

        return mBinding.getRoot();
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        mMap.setMyLocationEnabled(true);
        mMap.getUiSettings().setMyLocationButtonEnabled(false);
        mMap.setInfoWindowAdapter(new InfoWindowAdapter(getLayoutInflater()));
        animateCameraToUserLocation();
    }

What is the value of `LOCATION_REQUEST_INTERVAL_SECONDS`. Is it 30? if yes then it may take 30 seconds to get your first location. TO get it sooner you can use `setFastestInterval` to lower than `LOCATION_REQUEST_INTERVAL_SECONDS` — NinjaCoder, Nov 01 '17 at 20:06

What you can do is before the gps location is retrieved you could used the cached location with getLastLocation() , this will give you the last known location and will be faster than waiting for gps signal and get the updated location, you can always put a timer and if in 5 seconds the location has not been fetched with the gps, you can use getLastLocation()

An option could be retrying the operation, this was useful to me to get the location in background.

private suspend fun getLocation(context: Context): Location? {
    return suspendCoroutine { continuation ->
        try {
            if (!isLocationPermissionGranted(context)) {
                return@suspendCoroutine continuation.resume(null)
            }
            LocationServices.getFusedLocationProviderClient(context).run {
                var remainingTries = MAX_RETRIES_PER_LECTURE
                var location: Location? = null
                while (remainingTries > 0 && location == null) {
                    val locationTask = getCurrentLocation(priority, cancellationTokenSource.token)
                    location = Tasks.await(locationTask, 60, TimeUnit.SECONDS)
                    remainingTries--
                }
                continuation.resume(location)
            }
        } catch (e: Exception) {
            continuation.resumeWithException(e)
        }
    }
}
