I am working on creating my first android code, and I am having some problems.
I was using a dexv article for help on the code: http://www.devx.com/wireless/Article/43005/1954

I am getting the following errors when I write the code in eclipse:
The type new LocationListener(){} must implement the inherited abstract methodLocationListener.onLocationChanged (Location)
and
- Location cannot be resolved to a type

Here is the code:
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.location.LocationListener;
import android.location.LocationManager;


public class flightnav extends Activity {

/** Called when the activity is first created. */
@Override

public void onCreate(Bundle savedInstanceState) {
LocationManager locMan;
locMan = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, gpsListener);
}

LocationListener gpsListener = new LocationListener(){
Location curLocation;
boolean locationChanged = false;
public void onLocationChanged(Location location)
{
if(curLocation == null)
{
curLocation = location;
locationChanged = true;
}

if(curLocation.getLatitude() == location.getLatitude() &&
curLocation.getLongitude() == location.getLongitude())
locationChanged = false;
else
locationChanged = true;

curLocation = location;
}
public void onProviderDisabled(String provider){}
public void onProviderEnabled(String provider){}
public void onStatusChanged(String provider, int status, Bundle extras){}

};
}

Any help would be greatly appreciated.

Try now with this code

Thanks for the help, that resolved the errors that I had.
I now get the following warning message "The field new LocationListener(){}.locationChanged is never read locally" at this line of code:
boolean locationChanged = false;

One of the suggestions by eclipse is to add:
@SuppressWarnings("unused")

Am I missing something in the code, or is it just a warning message that can be ignored?

its not at all a problem
warning is because u are not using the variable(Reading the variable)..
