[android-developers] Lat, Longs are not changing even for new locations

Hi Friends,

This is kiran new to android. I am trying to find latitude and
longitude through NetworkProvider.

I got values for lat and langs when i am executing the applicarion
first time and the values are not changing even i am moving 200
meters far from current location.(I am executing newly in the new
location ie after 200 mt ) .

My code is as fallowing

public class WhereAmI extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LocationManager locationManager;
String context = Context.LOCATION_SERVICE;
locationManager = (LocationManager)getSystemService(context);
String provider = LocationManager.NETWORK_PROVIDER;
Location location =
locationManager.getLastKnownLocation(provider);

updateWithNewLocation(location);
}
private void updateWithNewLocation(Location location) {

String latLongString;
TextView myLocationText;

myLocationText = (TextView)findViewById(R.id.myLocationTxt);
if (location != null) {

double lat = location.getLatitude();
double lng = location.getLongitude();
double alt=location.getAltitude();
latLongString = "Lat:" + lat + "\nLong:" + lng+"\naltitude"+alt;
} else {
latLongString = "No location found";
}
myLocationText.setText("Your Current Position is:\n"
+latLongString);

}

}

what can i do for getting updated lat ,longs for new locations?

Can any one help me?

Thanks and Regards,

Kiran.
