gps activity stuck at onStart() - gps

Question

I wanted to call an activity to get the current gsp location and return the longitude and latidute but nothing happens, so i tried the simple following code from an programming book:
{private static final String TAG = GetGps.class.getSimpleName();
private LocationManager manager;
private LocationListener listener;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gps);
// LocationManager-Instanz ermitteln
manager = (LocationManager) getSystemService(LOCATION_SERVICE);
// Liste mit Namen aller Provider erfragen
List<String> providers = manager.getAllProviders();
// Infos zu Location Providern ausgeben
for (String name : providers) {
LocationProvider lp = manager.getProvider(name);
Log.d(TAG,
lp.getName() + " --- isProviderEnabled(): "
+ manager.isProviderEnabled(name));
Log.d(TAG, "requiresCell(): " + lp.requiresCell());
Log.d(TAG, "requiresNetwork(): " + lp.requiresNetwork());
Log.d(TAG, "requiresSatellite(): " + lp.requiresSatellite());
}
// Provider mit grober Auflösung
// und niedrigen Energieverbrauch
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
criteria.setPowerRequirement(Criteria.POWER_LOW);
// Namen ausgeben
String name = manager.getBestProvider(criteria, true);
Log.d(TAG, name);
// LocationListener-Objekt erzeugen
listener = new LocationListener() {
public void onStatusChanged(String provider, int status,
Bundle extras) {
Log.d(TAG, "onStatusChanged()");
}
public void onProviderEnabled(String provider) {
Log.d(TAG, "onProviderEnabled()");
}
public void onProviderDisabled(String provider) {
Log.d(TAG, "onProviderDisabled()");
}
public void onLocationChanged(Location location) {
Log.d(TAG, "onLocationChanged()");
if (location != null) {
String s = "Breite: " + location.getLatitude()
+ "\nLänge: " + location.getLongitude();
Toast.makeText(GetGps.this,
s,
Toast.LENGTH_LONG).show();
}
}
};
}
#Override
protected void onStart() {
super.onStart();
Log.d(TAG, "onStart()");
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 3000, 0,
listener);
}
#Override
protected void onPause() {
super.onPause();
Log.d(TAG, "onPause()");
manager.removeUpdates(listener);
}}
As i said, nothing happens, so here is the catlog:
