Problema Maps

Salve ragazzi,
ho provato la mia prima applicazione con le mappe di google maps, ma non riesco a visualizzare la mappa (quadratini grigi) nonostante abbia l'uses-permission di INTERNET e abbia la mia personale api-key.

Posto il codice:

public class GPS extends MapActivity
{
private LocationManager lm;
private LocationListener locationListener;

private MapView mapView;
private MapController mc;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map);

mapView = (MapView) findViewById(R.id.mapView);
mapView.setBuiltInZoomControls(true);

//---use the LocationManager class to obtain GPS locations---
lm = (LocationManager)
getSystemService(Context.LOCATION_SERVICE);

locationListener = new MyLocationListener();

lm.requestLocationUpdates(LocationManager.GPS_PROV IDER, 0, 0, locationListener);

mapView = (MapView) findViewById(R.id.mapView);
mc = mapView.getController();

}

@Override
protected boolean isRouteDisplayed() {

return false;
}

private class MyLocationListener implements LocationListener
{
@Override
public void onLocationChanged(Location loc) {
if (loc != null) {
Toast.makeText(getBaseContext(), "Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show();

GeoPoint p = new GeoPoint((int) (loc.getLatitude() * 1E6), (int) (loc.getLongitude() * 1E6));
mc.animateTo(p);
mc.setZoom(16);
mapView.invalidate();
}
}

@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
}
}

Questo è l'xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<com.google.android.maps.MapView
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:enabled="true"
android:clickable="true"
android:apiKey="0uXHhhRqm2iW_YBAtU3-gL_nwXYgIZvf5RAB83w"
/>

<LinearLayout android:id="@+id/zoom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
/>

</RelativeLayout>

Mentre il manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.Childroid.UI" android:versionCode="1" android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Main" android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<uses-library android:name="com.google.android.maps"></uses-library>
<activity android:name="com.prova.MAPS.GPS"></activity>
</application>
<uses-sdk android:minSdkVersion="7" />

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCAT ION"></uses-permission>
</manifest>

Idee a riguardo?
Ovviamente ho impostato i comandi nel eclipse.ini per la lingua in modo da non avere sempre 0,0 come coordinate.....

ora non ho sottomano le mie prove ma quella apikey mi pare strana...

Anchio voto per la apikey
