Why I'm getting NULL

[amrmb09]

i have the following structure..please tell me how to do what have you told me

public class CarCurrentPositionActivity extends Activity implements LocationListener
{..
 ...

 LocationListener loclisten = new CarCurrentPositionActivity();
        loclisten.onLocationChanged((Location) loclisten);
......
......
......
locationManager.requestLocationUpdates(...,...,...., loclisten);
...
...
}

public void onLocationChanged(Location loc) // accepts only arguments of type Location
{
...
...
}

You are using the same listener in two places. Its strange that you are passing a reference to the listener to the listener itself:
loclisten.onLocationChanged((Location) loclisten);
I have no idea why you would do that. ????
Why do you cast the listener to a Location? That does not make sense.

You didn't post the definition for LocationListener. Is the onLocationChanged method in that interface?

The locationManager object is given a reference to the listener. When the locationManger has a Location event it will call the listener.
