locationmanager

HI I tried to implement a simple GPS tracker. Therefore is used lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, this); Then i used the public void onLocationChanged(Location location) { method to read the altitude of my current location. But i dont really know what Location.getAltitude() returns. The document says it returns the altitude. But is this in meters? or feets? if i put the phone on the desk next to me, this value changes between 500 and -500?? How does this really work??? The altitude value you get

This question is directly related to the same prevailing stackoverflow question at " Android: get current location of user without using gps or internet " where the accepted answer is actually not answering the question. I should be able to get the current location name (eg:city name, village name) of the device via network provider not with GPS or internet. Following is the accepted answer in that question. (The following code parts should be included in the onCreate() method) // Acquire a reference to the system Location Manager LocationManager locationManager = (LocationManager) this

How do you get the current location of iPhone through code? I need to track the location using GPS. You're looking for the "CoreLocation" API. Here's a tutorial Roger There is (as always for core functionality) comprehensive documentation on the developer site and you may find this example useful; The key points to remember are; 1) Once you start receiving location updates, they arrive asynchronously and you need to respond to them as and when they come in. Check the accuracy and timestamps to decide if you want to use the location or not. 2) Don't forget to stop receiving updates as soon as

I'm trying to fix GPS programmatically when the GPS signal is not available. I want to do this in order to provide mock coordinates to other apps like google maps and others. I tried to use GPS_PROVIDER and NETWORK_PROVIDER but only with the latter I can get a new location valid for google maps. But this works only the first tima and if I want to re-fix more mock locations google maps doesn't see any change... why?? I have to do a service for what I want to do? public void setLocation(double latitude, double longitude) { //mocLocationProvider = LocationManager.GPS_PROVIDER; mocLocationProvider

I'm trying to retrieve location using LocationManager following this tutorial. I'm running the code on an android device running Marshmallow and I have checked the permission and running below code once the permission is granted. Here's my code: public Location getLocation() { try { locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); // getting GPS status isGPSEnabled = locationManager .isProviderEnabled(LocationManager.GPS_PROVIDER); // getting network status isNetworkEnabled = locationManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (!isGPSEnabled &&

This is my GPSTracker constructor class: public GPSTracker(Context context) { this.mContext = context; locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); Location gpsLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); Location networkLocation = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); } gpsLocation and networkLocation are always NULL. getLastKnowLocation method doesn't return me any Location... even if I'm sure that few second before lunching activity (and creating GPSTracker object) the device had network
