Manually updated updates stop working in Eclipse

I am working on 1.5 android app. Development in Eclipse 3.4.2 on Windows XP. I have a MapView, requested updates, etc.

The problem is that after the first manually entered GPS coordinate, the app stops recognizing that a GPS coordinate has been sent.

LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);  
MapController mc = mapView.getController();

TextView locationText = (TextView) findViewById(R.id.LocationBar);

LocationListener locationListener = new MyLocationListener(mc, itemizedOverlay, locationText);

lm.requestLocationUpdates(
    LocationManager.GPS_PROVIDER, 
    0, 
    0, 
    locationListener);   

      

        
        
        
      

    

Then MyLocationListener just changes the value in the TextView to match the new GPS coordinate.

public void onLocationChanged(Location loc) {
        if (loc == null) {
            return;
        }
        double lat = loc.getLatitude();
        double lng = loc.getLongitude();

        GeoPoint p = new GeoPoint(
            (int) (lat * 1E6), 
            (int) (lng * 1E6));

        mc.animateTo(p);

        itemizedOverlay.addOverlay(new OverlayItem(p, "title", "snippet"));

        String location = String.format("%f lat %f long", lat, lng);

        locationText.setText(location);

    }

      

        
        
        
      

    

I've added a few protocols to the onLocationChanged method and it only ever sees the location the first time I try to send an update. All subsequent ones do not trigger onLocationChanged method.

Additional Information:

The logcat output looks like this:

10-02 17:22:34.423: INFO/gps(6671): Provider gps is has status changed to 1. Extras: Bundle[mParcelledData.dataSize=52]

      

        
        
        
      

    

First GPS update faked:

10-02 17:22:49.383: INFO/gps(6671): Location provided by location provider: Location[mProvider=gps,mTime=-1000,mLatitude=25.0,mLongitude=23.0,mHasAltitude=true,mAltitude=0.0,mHasSpeed=false,mSpeed=0.0,mHasBearing=false,mBearing=0.0,mHasAccuracy=false,mAccuracy=0.0,mExtras=Bundle[mParcelledData.dataSize=52]]
10-02 17:22:49.444: INFO/gps(6671): Provider gps is has status changed to 2. Extras: Bundle[mParcelledData.dataSize=52]

      

        
        
        
      

    

According to http://developer.android.com/reference/android/location/LocationProvider.html#AVAILABLE , this 2 corresponds to "Available".

Once set to Available, no other locations will pass. Seems a bit controversial.
