android - MyLocationListener implements LocationListener - removeUpdates doesnt work -

i want put locationlistener in seperate class this:

public class mylocationlistener implements locationlistener{  @override public void onlocationchanged(location location) {  }  @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  }} 

it works, when trigger:

        locationmanager.removeupdates(mlistener); 

with mlistener mylocationlistener object, doesnt remove registered updates. onlocationchanged gets called on , on , on......

any help?
