Altitude always 0. I cannot obtain the altitude above sea level

Question

I get the altitude always 0. I want to obtain the altitude above sea level in Android using GPS. My code is: ``` public void onLocationChanged(Location location) { double lat = (double) (location.getLatitude()); double lng = (double) (location.getLongitude()); double alt = (double) (location.getAltitude()); latitudine = (int) (lat * 1e6); longitudine = (int) (lng * 1e6); altitudine = (int) (alt * 1e6); } ```

Accepted Answer

Did you check if this is device specific? Are you working in an emulator?

I would at first check, if your device supports the altitude determination with:

```
LocationManager locationManager; LocationProvider locationProvider;

/* Get LocationManager and LocationProvider for GPS */
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationProvider = locationManager.getProvider(LocationManager.GPS_PROVIDER);

/* Check if GPS LocationProvider supports altitude */
locationProvider.supportsAltitude();
```

If you want to know if a location has a valid altitude set, use the following:

```
Location location;

/* Get current location from GPS */
location = Location(LocationManager.GPS_PROVIDER);

/* Check if the requested Location has its altitude set */
location.hasAltitude();
```

Altitude always 0. I cannot obtain the altitude above sea level
