I try to realize a small app in codename one for iOS. I show a Google map in a dialoge. I want to show my actual and real location on the embedded map. I m shown on the map near 0N 0E - somewhere in the ocean. Here s the code I m using:
private void putMeOnMap(MapComponent map) {
Location loc;
try {
loc = LocationManager.getLocationManager().getCurrentLocation();
lastLocation = new Coord(loc.getLatitude(), loc.getLongitude());
Image i = Image.createImage(10, 10, 0xff00ff00); //("/red_pin.png");
PointsLayer pl = new PointsLayer();
pl.setPointIcon(i);
PointLayer p = new PointLayer(lastLocation, "aktueller Standort", i);
p.setDisplayName(true);
pl.addPoint(p);
pl.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
PointLayer p = (PointLayer) evt.getSource();
System.out.println("pressed " + p);
Dialog.show("Details", "Du bist hier" + "\n" + p.getLatitude() + "|" + p.getLongitude(), "Ok", null);
}
});
map.addLayer(pl);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Thanks for help
You need to explicitly ask and accept Location tracking when utilizing it in an iOS app.
It will look something like this:
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.locationServicesEnabled
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
...
var shouldIAllow = false
switch status {
case CLAuthorizationStatus.Restricted:
locationStatus = "Restricted Access to location"
case CLAuthorizationStatus.Denied:
locationStatus = "User denied access to location"
case CLAuthorizationStatus.NotDetermined:
locationStatus = "Status not determined"
default:
locationStatus = "Allowed to location Access"
shouldIAllow = true
}
if (shouldIAllow == true) {
NSLog("Location to Allowed")
// Start location services
locationManager.startUpdatingLocation()
} else {
NSLog("Denied access: \(locationStatus)")
}
I suggest using native mapping which looks much better on the device and also highlights your location as an option.
You should also use getCurrentLocationSync() rather than getCurrentLocation(). Notice that you must define the build hint ios.locationUsageDescription as explained here.

A short and simple question someone hopefully has an awnser to:
How can I navigate with the Here Android SDK Premium through road elemts that have the attributes DIR_NO_CARS, NO_THROUGH_TRAFFIC, DIR_NO_TRUCKS in the TRUCK transport mode? Like I am a special car and I can drive on these roads.
My code looks like the following:
public class Scratch extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
AndroidXMapFragment mapFragment = (AndroidXMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapfragment);
boolean success = com.here.android.mpa.common.MapSettings.setIsolatedDiskCacheRootPath(
getApplicationContext().getExternalFilesDir(null) + File.separator + ".here-maps",
"MainActivity");
System.out.println(success);
mapFragment.init(new OnEngineInitListener() {
#Override
public void onEngineInitializationCompleted(
OnEngineInitListener.Error error) {
if (error == OnEngineInitListener.Error.NONE) {
// now the map is ready to be used
Map map = mapFragment.getMap();
for (String sheme : map.getMapSchemes()) {
Log.d("Custom", sheme);
}
map.setMapScheme("pedestrian.day");
map.setMapDisplayLanguage(Locale.GERMANY);
//Show current position marker
PositioningManager.getInstance().start(PositioningManager.LocationMethod.GPS_NETWORK);
mapFragment.getPositionIndicator().setVisible(true);
//Routing
GeoCoordinate start = new GeoCoordinate(50.992189, 10.999966);
GeoCoordinate target = new GeoCoordinate(51.001224, 10.990920);
//Start - End marker for routing
MapLabeledMarker markerStart = new MapLabeledMarker(start)
.setLabelText(map.getMapDisplayLanguage(), "Start")
.setIcon(IconCategory.ALL);
markerStart.setZIndex(12);
map.addMapObject(markerStart);
MapLabeledMarker markerTarget = new MapLabeledMarker(target)
.setLabelText(map.getMapDisplayLanguage(), "End")
.setIcon(IconCategory.ALL);
markerTarget.setZIndex(12);
map.addMapObject(markerTarget);
CoreRouter router = new CoreRouter();
router.setDynamicPenalty(NewPenaltyForStreetArea(
router.getDynamicPenalty(),
new GeoCoordinate(51.001137, 10.989901),
new GeoCoordinate(50.992582, 10.999338),
map.getMapDisplayLanguage(),
"Im Geströdig",
DrivingDirection.DIR_BOTH,
70
));
RouteOptions routeOptions = new RouteOptions();
routeOptions.setTransportMode(RouteOptions.TransportMode.TRUCK);
routeOptions.setRouteType(RouteOptions.Type.FASTEST);

routePlan.addWaypoint(new RouteWaypoint(target));
class RouteListener implements CoreRouter.Listener {
// Method defined in Listener
public void onProgress(int percentage) {
// Display a message indicating calculation progress
Log.d("Custom", percentage + "");
}
// Method defined in Listener
#Override
public void onCalculateRouteFinished(List<RouteResult> routeResult, RoutingError error) {
// If the route was calculated successfully
if (error == RoutingError.NONE) {
// Render the route on the map
Log.d("Custom", routeResult.size() + " Routes calculated");
for (RouteResult result : routeResult) {
MapRoute mapRoute = new MapRoute(result.getRoute());
mapRoute.setColor(Color.argb(100, 201, 42, 42));
mapRoute.setZIndex(10);
if (routeResult.indexOf(result) == 0) {
//Best route
mapRoute.setColor(Color.argb(255, 201, 42, 42));
mapRoute.setZIndex(11);
}
map.addMapObject(mapRoute);
}
}
else {
// Display a message indicating route calculation failure
}
}
}
router.calculateRoute(routePlan, new RouteListener());
} else {
System.out.println("ERROR: Cannot initialize AndroidXMapFragment");
System.out.println(error);
}
}
});
}
private DynamicPenalty NewPenaltyForStreetArea(DynamicPenalty dynamicPenalty, GeoCoordinate cord1, GeoCoordinate cord2, String marcCode, String streetName, DrivingDirection drivingDirection, int speed){
List<GeoCoordinate> penaltyArea = new ArrayList<>();
penaltyArea.add(cord1);
penaltyArea.add(cord2);
List<RoadElement> roadElements = RoadElement.getRoadElements(GeoBoundingBox.getBoundingBoxContainingGeoCoordinates(penaltyArea), marcCode);
for (int i = 0; i < roadElements.size(); i++) {
//Log.d("Custom", roadElements.get(i).getRoadName());
if (!roadElements.get(i).getRoadName().equals(streetName)){
roadElements.remove(i);
i--;
}
else
Log.d("Custom", roadElements.get(i).getAttributes().toString());
}
Log.d("Custom", "Set penalty for " + roadElements.size() + " road elements - " + streetName);
for (RoadElement road : roadElements) {
dynamicPenalty.addRoadPenalty(road, drivingDirection, speed);
}
return dynamicPenalty;
}
}
And this is what I get
But this is what I need
So I want to say the navigation API that the road "Im Geströdig" is accessible for my car.
Road Element Attributes I need to change somehow:
[DIR_NO_CARS, DIRT_ROAD, NO_THROUGH_TRAFFIC, DIR_NO_TRUCKS]
The solution to the use case is not trivial. The functionality of updating Road Element attributes is available via the HERE Custom Route API, where you would need to upload an overlay with a shape, that matches the road you want to modify. The attributes which can be updated are also limited. ("VEHICLE_TYPES":"49" indicates road is open for Cars, Truck, Pedestrian)
GET http://cre.api.here.com/2/overlays/upload.json
?map_name=OVERLAYBLOCKROAD
&overlay_spec=[{"op":"override","shape":[[50.10765,8.68774],[50.10914,8.68771]],"layer":"LINK_ATTRIBUTE_FCN","data":{"VEHICLE_TYPES":"49"}}]
&storage=readonly
&app_id={YOUR_APP_ID}
&app_code={YOUR_APP_CODE}
Make sure to use the same AppId, Appcode as being used with HERE Premium Mobile SDK.
Now this overlay can be used in HERE Premium Mobile SDK with FTCRRouter (still Beta feature)
FTCRRouter ftcrRoute = new FTCRRouter();
FTCRRouter.RequestParameters parmaters =new
FTCRRouter.RequestParameters(routePlan,"OVERLAYBLOCKROAD",true);
ftcrRoute.calculateRoute(parmaters, new FTCRRouter.Listener() {
#Override
public void onCalculateRouteFinished(List<FTCRRoute> list,
FTCRRouter.ErrorResponse errorResponse) {
if (errorResponse.getErrorCode() == RoutingError.NONE) {
List<GeoCoordinate> shape = list.get(0).getGeometry();
MapPolyline polyline = new MapPolyline();
polyline.setGeoPolyline(new GeoPolygon(shape));
polyline.setLineWidth(10);
m_map.addMapObject(polyline);
}else{
// Error
}
}
});
As the FTCRRouter is still in Beta, there are some limitation like Dynamic Penanlity is not supported and also the FTCRRouter always prefers to take the roads available in HERE Map data and uses the Roads from the overlay if necessary.
Hello so I though I was getting user location through this code but im actually getting the server's location, any idea how can I change it so I get the user location?
public void geolocate() {
try {
GeolocationPayloadBuilder payloadBuilder = new GeolocationPayload.GeolocationPayloadBuilder();
GeolocationPayload payload = payloadBuilder.createGeolocationPayload();
//GeoApiContext context = new GeoApiContext.Builder().apiKey("my api key").build();
// I guess the payload needs to be build in a different way but no clue how it should be :/
GeolocationApiRequest req = (GeolocationApiRequest) GeolocationApi.geolocate(context, payload);
GeolocationResult res = req.await();
String location = res.location.toString();
String[] latLngArray = location.split(",");
com.google.maps.model.LatLng latLng = new com.google.maps.model.LatLng(Double.parseDouble(latLngArray[0]),
Double.parseDouble(latLngArray[1]));
GeocodingApiRequest geoReq = GeocodingApi.reverseGeocode(context, latLng);
GeocodingResult[] geoRes = geoReq.await();
// Setting the user location for view
System.out.println(geoRes[0].formattedAddress);
origen.setValue(geoRes[0].formattedAddress);
} catch (Exception e) {
System.out.println("Exception in NetClientGet:- " + e);
}
}
this is the dependency where im getting the objects from:
<dependency>
<groupId>com.google.maps</groupId>
<artifactId>google-maps-services</artifactId>
<version>0.9.3</version>
</dependency>
hope somebody can help me with this, thanks in advance
EDIT:
I have been searching and found out how to build the payload with help of https://developers.google.com/maps/documentation/geolocation/intro#cell_tower_object
But I have a couple of question which is how will I get my users mac address to create the wifiAccessPoint and also where do I find info of cell towers in my city (Cali, Colombia)? Just an update will keep searching any help is appreciated..
#POST
#Path("/geolocate")
public String geolocate() {
try {

.MobileCountryCode(310).MobileNetworkCode(410).Age(0).createCellTower();
WifiAccessPoint newWifiAccessPoint = new WifiAccessPoint.WifiAccessPointBuilder()
.MacAddress("00:25:9c:cf:1c:ac").createWifiAccessPoint();
WifiAccessPoint newWifiAccessPoint2 = new WifiAccessPoint.WifiAccessPointBuilder()
.MacAddress("00:25:9c:cf:1c:ad").createWifiAccessPoint();

.ConsiderIp(false).AddCellTower(newCellTower).AddWifiAccessPoint(newWifiAccessPoint)
.AddWifiAccessPoint(newWifiAccessPoint2);
GeolocationPayload payload = payloadBuilder.createGeolocationPayload();
GeoApiContext context = new GeoApiContext.Builder().apiKey("my api key")
.build();
GeolocationApiRequest req = (GeolocationApiRequest) GeolocationApi.geolocate(context, payload);
GeolocationResult res = req.await();

GeocodingResult[] geoRes = geoReq.await();
// Setting the user location for view
return geoRes[0].formattedAddress;
} catch (Exception e) {
System.out.println("Exception in NetClientGet:- " + e);
}
return "XD";
}
The Geolocation API of Google Maps Platform is not intended for getting user location, what I can suggest is that you use the HTML5 Geolocation instead, there's also a sample of that in the Google Maps Platform documentation. But please note that this is not supported by Google as this is using HTML5 Geolocation and not Google APIs, if you wish to get the address of the user location as well, you may Geocode the coordinates that will be returned by the HTML5 Geolocation. You may see the sample below (without the Geocoding function). Here's a working sample - https://jsfiddle.net/w2sad5pn/
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
infoWindow.setPosition(pos);
infoWindow.setContent('Location found.');
infoWindow.open(map);
map.setCenter(pos);
}, function() {
handleLocationError(true, infoWindow, map.getCenter());
});
} else {
// Browser doesn't support Geolocation
handleLocationError(false, infoWindow, map.getCenter());
}
}
I'm looking for one way to share a non-parcelable item from my application and my current Service. This is the situation:
I have a Service to store all the media data from a camera application, photos, videos etc. The mission of this service is continue saving the media when the user go to background. When I did this in a first instance, I had a lot of SIGSEGV errors:
08-22 10:15:49.377 15784-15818/com.bq.camerabq A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8c3f4000 in tid 15818 (CameraModuleBac)
This was because the Image item that I recover from my imageReaders are not parceable, I fix this saving the Bytebuffers from the image instead of the whole image item.
But, now I'm getting the same problem with DNG captures, because from my imageReader I got a CaptureResult item that I need to use to create a DngCreator item to write the dng image.
CaptureResults and DngCreators are not parcelables or Serializables, so I don't find a way to save my data from the application to recover it in the service if I'm in background.
I have tried to copy the reference when calling the Service and it didn't worked. Also I saw in other posts as Object Sharing Between Activities in Android and Object Sharing Between Activities in Android that I can save the item in a static reference in my application context to be able to recover it in different activities. So finally I tried this:
public class DngManager extends Application {
public static DngManager sDngManagerInstance;
protected Hashtable<String, CaptureResult> dngCaptureResults;
private static String DNG_KEY_PREFIX = "dngResult_";
public DngManager(){
super();
createDNGCaptureResults();
}
public void createDNGCaptureResults() {
dngCaptureResults = new Hashtable<String, CaptureResult>();
}
public boolean addDNGCaptureResultToSharedMem(long dateKey, CaptureResult value) {
dngCaptureResults.put(DNG_KEY_PREFIX + dateKey, value);
return true;
}
public CaptureResult getFromDNGCaptureResults(long dateKey) {
return dngCaptureResults.get(DNG_KEY_PREFIX + dateKey);
}
private boolean containsDNGCaptureResults(long dateKey) {
return dngCaptureResults.containsKey(DNG_KEY_PREFIX + dateKey);
}
public void clearDNGCaptureResults(long dateKey) {
String partKey = String.valueOf(dateKey);
Enumeration<String> e2 = dngCaptureResults.keys();
while (e2.hasMoreElements()) {
String i = (String) e2.nextElement();
if (i.contains(partKey))
dngCaptureResults.remove(i);
}
}
public static DngManager getInstance(){
if (sDngManagerInstance == null){
sDngManagerInstance = new DngManager();
}
return sDngManagerInstance;
}
}
And later I recover it in my service:
CaptureResult dngResult = ((DngManager)getApplication()).getFromDNGCaptureResults(mDngPicture.getDateTaken());
if (dngResult == null) {
return;
}
DngCreator dngCreator = new DngCreator(mCameraCharacteristics, dngResult);
path = Storage.generateFilepath(title, "dng");
file = new File(Uri.decode(path));
try {
Log.e(TAG, "[DngSaveTask|run] WriteByteBuffer: Height " + mDngPicture.getSize().getHeight() + " Width " + mDngPicture.getSize().getWidth());
OutputStream os = new FileOutputStream(file);
dngCreator.writeByteBuffer(os, mDngPicture.getSize(), mDngPicture.getDngByteBuffer(), 0);
} catch (IOException e) {
Log.d(TAG, "[DngSaveTask|run] " + e);
e.printStackTrace();
}
dngCreator.close();
Log.e(TAG, "[DngSaveTask|run] Cleaning Result from shared memory");
DngManager.getInstance().clearDNGCaptureResults(mDngPicture.getDateTaken());
MediaScannerConnection.scanFile(getApplicationContext(), new String[]{file.getAbsolutePath()}, null, null);
Anyway, it still giving me back a SIGSEGV error. What else can I try?
I would like to get back results in a variable of type String. The contents of what the user tells his smartphone via Google now that is: "OK google claptrap " I would like to do this so I could get back 'claptrap'. I have already searched but have been unsuccessful. I found how to return my selectable application in Google now like, for example write a note in my app but in this case the person has to say " OK google note at me claptrap " so that I can get back claptrap. It is not proceeding well … I am pretty sure that it is possible because the app "commandr" already makes it for commands as "turn on the torch".
Excuse my bad english.
Thank you in advance Good evening :D

can anyone please tell me how to use google places api in android. I am developing this application in eclipse where i need to find the nearest petrol stations and garages near my area. I went through numerous websites. i didnt find a proper answer. I need a sample code since i am new to json concepts.
public class place {

private static final boolean PRINT_AS_STRING = false;
public void performSearch() throws Exception {
try {
System.out.println("Perform Search ....");
System.out.println("-------------------");
HttpRequestFactory httpRequestFactory = createRequestFactory(transport);
HttpRequest request = httpRequestFactory.buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
request.url.put("key", "api key");
request.url.put("location", lat + "," + lng);
request.url.put("radius", 500);
request.url.put("sensor", "false");
if (PRINT_AS_STRING) {
System.out.println(request.execute().parseAsString());
} else {
PlacesList places = request.execute().parseAs(PlacesList.class);
System.out.println("STATUS = " + places.status);
for (Place place : places.results) {
System.out.println(place);
}
}
} catch (HttpResponseException e) {
System.err.println(e.response.parseAsString());
throw e;
}
}//StoresNearMe
You can use Google API Java Client for Google Places API in Android . See my answer for a short snippet https://stackoverflow.com/a/12824796/1147466
