Hi ,
This is the code written to get the current location....
private boolean getCordinates() {
// TODO Auto-generated method stub
locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
locationManager.removeUpdates(locationListener);
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
};
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
0,
0, locationListener);
location = locationManager.getLastKnownLocation("gps");
if(location != null){
latitude = location.getLatitude();
longitude = location.getLongitude();
return true;
} else {
return false;
}
}
Have used getlastKnownLocation() to get the recently updated lat and
longt values....My doubt is how abt the user switches off the gps at
location A and further moving to another location B switch on the gps
gets what value in getLastKnownLocation()....
Like to have your suggestion on how to get the user's current
location.....
Thankful for your reply...
regards,
sheik
