get the Latitude and Longitude in Blackberry
If you did an Andriod development then there is 1 function to get the latitude and longitude for perticular location called GeoPoint. Is it possible in blackberry where I placed the marker on the map: get lat and long for perticular location in the map, in any OS 5, 6 OR 7.
Alternative option is reverse - geocoding I wanted to get all of this if it is possible for any google or blackberry card
Thanks in advance
Hi Peter had u check the andriod functionality?
Its ok I use https://developers.google.com/maps/documentation/geocoding/
Thanks for your helpI tried to get it, but I don't have a good way to do that as an andriod.

How to convert latitude and longitude bb10 postal code?
Hi, I want to know how to get the zip code of North latitude and longitudein BB10. I had the latitude, longitude and now I need to convert it to a zip code.
I tried under document bb10 code
/Reverse GeoCoding QStringList serviceProviders = QGeoServiceProvider::availableServiceProviders(); if (serviceProviders.size()) { QGeoServiceProvider *serviceProvider = new QGeoServiceProvider( serviceProviders.at(0)); QGeoSearchManager *searchManager = serviceProvider->searchManager(); //searchManager->setProperty("boundary", "city"); reply = searchManager->reverseGeocode(QGeoCoordinate(lat,long)); bool finished_connected = QObject::connect(reply, SIGNAL(finished()), this, SLOT(readReverseGeocode())); bool error_connected = QObject::connect(reply, SIGNAL(error(QGeoSearchReply::Error, QString)), this, SLOT(reverseGeocodeError(QGeoSearchReply::Error, QString))); //Reverse GeoLocation void LocationHandler::readReverseGeocode() { QList

How can I get exact latitude and longitude by GPS to PhoneGap.
I use geolocation plugin to get lat, long but it still fluctuates after the fourth decimal place (means give fluctuation of 11 m from my current position). I tried to search on this problem and I got GPS (GPS + Glonass) Fixer (download mirror one... |) Samsung Galaxy Note II GT-N7100, N7105 , but do not know how to use it. So, can we use gps + glonass to phonegap to get the exact location if that please give me a better solution to get the right latitude longitude. Please suggest me.
Short answer: forget it.
Longer answer: as any geocacher known, the GPS is not reliable per metre (3 ft). May fluctuate, and once you're in the right place, you know that you could be several metres (20 ft) wide.

Problem during recovery latitude and longitude
Hello
I'm trying to get the latitude and longitude using LocationListener, but every time I try to seek always returns 0.0. I've implemented the locationUpdated method, but there it always returns 0.0 for i.e. latitude and longitude. After when I started with Blackberry Maps and start the GPS Navigation in Blackberry Maps menu, so I start receiving the latitude and longitude after awhile.
Can someone tell what I am doing wrong? Am I missing something?
import javax.microedition.location.LocationListener; import javax.microedition.location.Location; import javax.microedition.location.LocationProvider; import javax.microedition.location.LocationException; import javax.microedition.location.Coordinates; import javax.microedition.location.Criteria; public class GPSLocationListener { Location location = null; LocationProvider locationProvider = null; //Coordinates cords = null; //Criteria criteria = null; int interval = 90; //seconds - this is the period of position query int timeout = 90; //seconds - this is the timeout period. static double _lat = 0.0000; static double _lon = 0.0000; public GPSLocationListener() { try { locationProvider = LocationProvider.getInstance(null); if(locationProvider != null) { locationProvider.setLocationListener(new LocationListenerImpl(), interval, timeout, -1); } } catch(LocationException le) { System.out.println("Location Exception : "); } } private static void setLat(double lat) { _lat = lat; } public static double getLat() { return _lat; } private static void setLon(double lon) { _lon = lon; } public static double getLon() { return _lon; } /** * Implementation of the LocationListener interface */ private class LocationListenerImpl implements LocationListener { public void providerStateChanged(LocationProvider provider, int newState) { //no operation needs to be performed for this method. } public void locationUpdated(LocationProvider provider, Location location) { if(location.isValid()) { double latitude = location.getQualifiedCoordinates().getLatitude(); double longitude = location.getQualifiedCoordinates().getLongitude(); //set the latitude and longitude values fetched here. setLat(latitude); setLon(longitude); } } } }
I pasted the source code for the extraction of latitude and longitude. Please let me know if there is a problem.
Hello
I have solved the problem.
I was not any operation in the providerStateChanged method and I think of what he would always return 0.0 always. I modified the code today and as shown as below:
class LocationListenerImpl implements LocationListener { public void providerStateChanged(LocationProvider provider, int newState) { if(newState == LocationProvider.TEMPORARILY_UNAVAILABLE) { locationProvider.reset(); locationProvider.setLocationListener(null, interval, timeout, -1); //Make the thread to sleep for some time. try { Thread.sleep(2000); } catch(Exception e) { System.out.println("Exception while making the thread to sleep"); } startGpsNavigation(); } } public void locationUpdated(LocationProvider provider, Location location) { if(location.isValid()) { double latitude = location.getQualifiedCoordinates().getLatitude(); double longitude = location.getQualifiedCoordinates().getLongitude(); //set the latitude and longitude values fetched here. setLat(latitude); setLon(longitude); } } private void startGpsNavigation() { try { locationProvider = LocationProvider.getInstance(null); if(locationProvider != null) { locationProvider.setLocationListener(new LocationListenerImpl(), interval, timeout, -1); } } catch(LocationException le) { System.out.println("Location Exception : "); } } }
Once the LocationProvider is temporary unavailable I am reintializing it in startGpsNavigation.
I hope this is the right approach because it solved my problem. Now, I'm getting latitude and longitude without having to start Blackberry Maps.
Hope it would help someone else too.

GPS latitude and longitude are not when no signal
Hello
I am buliding a BB 9700 GPS application. I am able to get the latitude and longitude through cellTower (using the Service Provider signal), but I am unable to get the latitude and longitude when there is no signal. I tried the criteria to false, but the lattude and longitude do not come.
Please find the code below
private LocationProvider _provider; private Criteria _criteria; boolean deviceReciever,cellSignal; String longitude, latitude,altitude,speed; private void FixLocation() { resetProvider(); /** Initialize Criteria and LocationProvider instances. */ deviceReciever = true;//receiving lattitude and longitude to phone gps reciever cellSignal; = false;//Disabling ph signals setupCriteria(); createLocationProvider(); if(_provider!=null){ try{ _location = _provider.getLocation(5); locationUpdated(_provider, _location); }catch(InterruptedException e){ //log(e.getMessage()); System.out.println("Exception called --->"+e); }catch(LocationException e) { //log(e.getMessage()); System.out.println("Exception called --->"+e); } /*--> try { System.out.println("babaji"); System.out.println("The _interval="+_interval); _interval = -1; _provider.setLocationListener(this, _interval, 10, 20); } catch(Exception e) { System.out.println("Exception called-->"+e); } */ } } private void resetProvider() { if (_provider != null) { _provider.setLocationListener(null, 0, 0, 0); _provider.reset(); _provider = null; } } private void setupCriteria() { _criteria = new Criteria(); if( deviceReciever == true ) { _criteria.setCostAllowed(false); } else if( cellSignal == true ) { _criteria.setHorizontalAccuracy(Criteria.NO_REQUIREMENT); _criteria.setVerticalAccuracy(Criteria.NO_REQUIREMENT); _criteria.setCostAllowed(true); _criteria.setPreferredPowerConsumption(Criteria.POWER_USAGE_LOW); } } private void createLocationProvider() { /** * Initialize _provider using _criteria. */ try { _provider = LocationProvider.getInstance(_criteria); } catch (LocationException e) { } } public void locationUpdated(LocationProvider provider, Location location) { if (location != null && location.isValid()) { QualifiedCoordinates coordinates = location .getQualifiedCoordinates(); speed = Float.toString(location.getSpeed()); longitude = Double.toString(coordinates.getLongitude()); latitude = Double.toString(coordinates.getLatitude()); altitude = Float.toString(coordinates.getAltitude()); System.out.println("Longitude --->"+coordinates.getLongitude()); System.out.println("Latitude---->"+coordinates.getLatitude()); System.out.println("Altitude->"+coordinates.getAltitude()); } }
The longitude and latitude are coming as null always if we I'm reciving the gps via the mobile gps receiver. If the signal of the mobile service provider then uses the lang and lat come.
I don't want to use the service provier signal for lattitude and longitude.
Please suggest me the error I made in the above code and assistance.
Thanking you
Standalone GPS works best outdoors, with a clear view of the sky. At the very least, near a window.
You can experiment with the timeout.

How can I get my current coordinates (latitude and longitude)?
Hello world
I'm trying to design an application, but I don't know if I want to do is possible.
I want to choose the current place of residence and then display in a map.
Something like:
MapView mapview = new MapView();
Ask my current location lat and LNG somehow and save them in the lat, long variables.
mapview.setLatitude (lat);
mapview.setLongitude (lng);
mapview.setZoom (4);
Invoke.invokeApplication (Invoke.APP_TYPE_MAPS, new MapsArguments (mapview));
(I mean, I want to show a different mapView depending on where I am)
My problem: can be found my current latitude and longitude? How can I do?
I'm completely lost on how to start looking for information, then I'll be happy to receive any help.
Kind regards

How to get the width and height of Flex Mobile view?
Hello
The following instructions can get the width and height of the current Flex app:
var request: UIComponent = FlexGlobals.topLevelApplication as UIComponent;
trace (application. Width);
trace (application. Height);
But I don't know how to get the width and height of mobile display Flex current (i.e. the content size excludes bar action and the Navigation bar). Why the "this.width" always returns 0?

Values of latitude and Longitude
Hello
I am new to Oracle optional, if I need to store values of coordinates of latitude and logitude as Oracle Spatial.What the values of coordinates of latitude and logitude should be?
Y at - it standard latitude and longitude for Oracle Spatials format.
Usually what format I have to do and what conversion I must used to store on the SDO_GEOMETRY object.
If you give examples, it would be really useful.
Thank you
VinoThe ordered values are stored as decimal numbers.
For example, the value of longitude 147 degrees, 30 minutes is stored as 147,5.
In addition, lat/long data is actually stored in a SDO_GEOMETRY object in longitude, latitude order (latitude, longitude, not).
Thus, a point 147.5 long and-32,5 latitude is stored:
SDO_GEOMETRY(2001,8311,SDO_POINT_TYPE(147.5,-32.5,NULL),NULL,NULL)
I hope this helps.
