misaligned coordinates android

Hi I am making an android app which uses an OpenStreetMap. I have my own tile server which serves the street map.

When I tell the app to centre on a specifc area on the map by passing in the coordinates as a GeoPoint, it centres somewhere around Africa when it should centre on Edinburgh.

Here is the code:

// osm map view 
MapView osmMap;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    osmMap = (MapView) findViewById(R.id.mapview);
    osmMap.setMultiTouchControls(true);

    // Create custom map source pointing to Tile Server
    XYTileSource myMapSource = new XYTileSource("myMap", null, 0, 16, 256, ".png", Constants.LOCAL_SERVER_URL);

    // Set the source and default map coordinates/zoom
    osmMap.setTileSource(myMapSource);

    osmMap.getController().animateTo(new GeoPoint(55.95223359877632*1e6, -3.188550710678032*1e6));
    osmMap.getController().setZoom(Constants.DEFAULT_ZOOM); 
}

Anyone know how I can get the coorindates to align with the map correctly?

Thanks
