android-discuss, geo fix in emulator - strange pattern in gps fix timestamps

1. GPS code works in HTC machines but fails in MOTO's

Excellent advice!

(though, a nit: in your first bullet, perhaps you mean onCreate() for
the activity, since there is no onCreate() for View)

2. GPS code works in HTC machines but fails in MOTO's

My code to obtain GPS coordinate works perfect in HTC cells. But I
find it doesn't work in Moto Droid. I debug it and find eveything
seems fine. But the coordinate never obtained. Please read my code
first:

/////////// defining listener
        LocationListener locationListener = new LocationListener() {

                @Override
                public void onStatusChanged(String provider, int status, Bundle
extras) {
                }

                @Override
                public void onProviderEnabled(String provider) {}

                @Override
                public void onProviderDisabled(String provider) {}

                @Override
                public void onLocationChanged(Location location) {
                        stateGPS = PR.Types.SERVICE_ACTION_STATE_UPDATED;
                        currentPosition.latitude = location.getLatitude();
                        currentPosition.longitude = location.getLongitude();

                        locationManager.removeUpdates(locationListener);
                }
        };

.....
//////////updating location information
boolean gpsEnabled = false;
                if 
(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
{
                        new Handler(getMainLooper()).post(new Runnable() {

                                public void run() {
        
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
0, 0, locationListener);
                                }
                        });

                        gpsEnabled = true;
                }

                if
(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
{
                        new Handler(getMainLooper()).post(new Runnable() {

                                public void run() {
        
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
0, 0, locationListener);
                                }
                        });

                        gpsEnabled = true;
                }
.....
//////////////fetching coordinate
Location l = null;
                                if
(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                                        l =
locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                                }

                                if (l == null &&
locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
                                        l =
locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                                }

                                locationManager.removeUpdates(locationListener);

                                if (l == null) {
                                        //gps unknown
                                        stateGPS = 
PR.Types.SERVICE_ACTION_STATE_OTHER;
                                        return;
                                } else {
                                        currentPosition.latitude = 
l.getLatitude();
                                        currentPosition.longitude = 
l.getLongitude();
                                        stateGPS = 
PR.Types.SERVICE_ACTION_STATE_UPDATED;
                                }
....

No error message, No fatal return. Every things invoked well, but
onLocationChanged() never be run, getLastKnownLocation() always return
null ----- No GPS information get at all. I check all the settings.
GPS device is opened and every thing is OK. The same code works in my
HTC magic, G2.

Please help me. Thank you!
