View Full Version : [Android] SKNavigationType.REAL - reportNewGPSPosition

Hey Forum,

iam new in the Skobbler SDK world.

Ive followed the instructions of ""How to" for the Android SDK". The map is showed and i can rotate, zoom,...
Then i tryed the navigation module with "Navigating a route". When i use the example code snippet (see below), everything works fine.

public void onAllRoutesCompleted() {
SKNavigationSettings navigationSettings = new SKNavigationSettings();
navigationSettings.setNavigationType(SKNavigationS ettings.SKNavigationType.SIMULATION);

SKNavigationManager navigationManager = SKNavigationManager.getInstance();
navigationManager.setNavigationListener(ActivityMa p.this);
navigationManager.startNavigation(navigationSettin gs);
skToolsNavigationInProgress = true;

After changing to SKNavigationType.REAL there is only the route displayed. Ive implemented my on location listener for adjusting LocationManager.requestLocationUpdates with different Criteria. After i received an location update i use the following code:

public void positionUpdate(LatLng currentPosition, float accuracy) {
SKPosition skPosition = new SKPosition(currentPosition.longitude, currentPosition.latitude, (double) 0.0, (double) accuracy, (double) 0.0, 0.0D, 0.0);
SKPositionerManager.getInstance().reportNewGPSPosi tion(this.currentPosition);

But now nothing happens with the initial current position of the calculated and displayed route. What am I doing wrong?

Im getting updates regularly with onUpdateNavigationState - it seems that something is working in the background but just without position updates.

As you can see in my attachments the current position is updated and showed as a SKAnnotation (left image is the first update (gps, very bad accuracy), right image the second (via wlan with good accuracy))

Best regards,

Hey Forum,

if i move with GPS in the real word the SDK perform location updates at the map view.

But if i want to emulate several updates at the position far away, nothing happens (see Attachment). Why? :/ I there a threshold for a minimum distance or a minimum count of position update until the map gets updated?

You shouldn't do that by yourself .. SKMaps can do this good enough without your assistance ..

public void onCurrentPositionUpdate(SKPosition curpos) {

if (curpos != null && mapView != null) {
mapView.reportNewGPSPosition(this.currentPosition) ;
* Current position provider
private SKCurrentPositionProvider currentPositionProvider;

protected void onCreate(Bundle savedInstanceState) {
currentPositionProvider = new SKCurrentPositionProvider(this);
currentPositionProvider.setCurrentPositionListener (this);
currentPositionProvider.requestLocationUpdates(tru e, true, true);
currentPositionProvider.requestUpdateFromLastPosit ion();

Anyway, I'm facing the huge GPS position "jumps" at home as well .. sometimes even around 500-800m from my current position with WLAN .. I think that's because of poor device ..
My colleague hasn't such problems with iPhone.
