Problem of getting my current location.

Hallo, i have tried to get my current location using osmdroid, then getting the location of the client address from database.

First, i make it sure that i have the permissions inside manifestfile.xml:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

I am implementing the map related code inside a Fragment. My problem is that i can not get my current location, i have tried the following:

private void trackingMyLocationTow() { locationProvider = new GpsMyLocationProvider(this); myLocationoverlay = new MyLocationNewOverlay(locationProvider, mapView); myLocationoverlay.enableMyLocation(); myLocationoverlay.setDrawAccuracyEnabled(true); myLocationoverlay.runOnFirstFix(new Runnable() { public void run() { myLatitude = myLocationoverlay.getMyLocation().getAltitude(); myLongitude = myLocationoverlay.getMyLocation().getLongitude(); } }); mapView.getOverlays().add(myLocationoverlay); mapView.invalidate(); }

Then i got 0 for both myLatitude and myLongitude.

I have also tried to get my current location using another code:

`import android.app.Service; import android.content.Context; import android.content.Intent; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.os.IBinder; import android.util.Log; import android.widget.Toast;

public class LocationService extends Service { public static final String BROADCAST_ACTION = “Hello World”; private static final int TWO_MINUTES = 1000 * 60 * 2; public LocationManager locationManager; public MyLocationListener listener; public Location previousBestLocation = null;

Intent intent;
int counter = 0;

@Override
public void onCreate()
{
    super.onCreate();
    intent = new Intent(BROADCAST_ACTION);
}

@Override
public void onStart(Intent intent, int startId)
{
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    listener = new MyLocationListener();
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 4000, 0, listener);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 4000, 0, listener);
}

@Override
public IBinder onBind(Intent intent)
{
    return null;
}

protected boolean isBetterLocation(Location location, Location currentBestLocation) {
    if (currentBestLocation == null) {
        // A new location is always better than no location
        return true;
    }

    // Check whether the new location fix is newer or older
    long timeDelta = location.getTime() - currentBestLocation.getTime();
    boolean isSignificantlyNewer = timeDelta > TWO_MINUTES;
    boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES;
    boolean isNewer = timeDelta > 0;

    // If it's been more than two minutes since the current location, use the new location
    // because the user has likely moved
    if (isSignificantlyNewer) {
        return true;
        // If the new location is more than two minutes older, it must be worse
    } else if (isSignificantlyOlder) {
        return false;
    }

    // Check whether the new location fix is more or less accurate
    int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy());
    boolean isLessAccurate = accuracyDelta > 0;
    boolean isMoreAccurate = accuracyDelta < 0;
    boolean isSignificantlyLessAccurate = accuracyDelta > 200;

    // Check if the old and new location are from the same provider
    boolean isFromSameProvider = isSameProvider(location.getProvider(),
            currentBestLocation.getProvider());

    // Determine location quality using a combination of timeliness and accuracy
    if (isMoreAccurate) {
        return true;
    } else if (isNewer && !isLessAccurate) {
        return true;
    } else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) {
        return true;
    }
    return false;
}



/** Checks whether two providers are the same */
private boolean isSameProvider(String provider1, String provider2) {
    if (provider1 == null) {
        return provider2 == null;
    }
    return provider1.equals(provider2);
}

@Override
public void onDestroy() {
    // handler.removeCallbacks(sendUpdatesToUI);
    super.onDestroy();
    Log.v("STOP_SERVICE", "DONE");
    locationManager.removeUpdates(listener);
}

public static Thread performOnBackgroundThread(final Runnable runnable) {
    final Thread t = new Thread() {
        @Override
        public void run() {
            try {
                runnable.run();
            } finally {

            }
        }
    };
    t.start();
    return t;
}


public class MyLocationListener implements LocationListener {

    public void onLocationChanged(final Location loc) {
        if(isBetterLocation(loc, previousBestLocation)) {
            Toast.makeText( getApplicationContext(), "Your Lat is:"+loc.getLatitude(), Toast.LENGTH_LONG).show();
            Toast.makeText( getApplicationContext(), "Your Lng is:"+loc.getLongitude(), Toast.LENGTH_LONG).show();
            loc.getLatitude();
            loc.getLongitude();
            intent.putExtra("Latitude", loc.getLatitude());
            intent.putExtra("Longitude", loc.getLongitude());
            intent.putExtra("Provider", loc.getProvider());
            sendBroadcast(intent);
        }
    }

    public void onProviderDisabled(String provider) {
        Toast.makeText( getApplicationContext(), "Gps Disabled", Toast.LENGTH_LONG).show();
    }


    public void onProviderEnabled(String provider) {
        Toast.makeText( getApplicationContext(), "Gps Enabled", Toast.LENGTH_LONG).show();
    }


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

    }

}

} ` And again i got 0 for both lat and lng.

are you outside with gps service? does the device even have gps? is the gps turned on?

Hmm, did you do the whole permissions thing?
