Location returns always null from this code. Please check my codes and tell me whats wrong. When I run the project on debug mode, provider="network" but location always null. I send latitude and longitude values by using DDMS but doesn't change. I don't understand whats is the problem
This part in the onCreate method
lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
criteria.setPowerRequirement(Criteria.POWER_LOW);
provider = lm.getBestProvider(criteria, true);
location = lm.getLastKnownLocation(provider);
updateLocation(location);
This part in the onResume method
@Override
protected void onResume() {
super.onResume();
lm.requestLocationUpdates(provider, 5000, 10, this);
}
I use LocationListener (MapActivity implements LocationListener) and this is onLocationChanged part
public void onLocationChanged(Location location) {
updateLocation(location);
}
finally this is my updateLocation()
private void updateLocation(Location location){
if (location != null) {
Double lat = location.getLatitude()*1E6;
Double lng = location.getLongitude()*1E6;
point = new GeoPoint(lat.intValue(), lng.intValue());
mapView = (MapView) findViewById(R.id.mapView);
mc = mapView.getController();
mapView.setBuiltInZoomControls(true);
//List<Overlay> overlays = mapView.getOverlays();
myLocOverlay = new MyLocationOverlay(this, mapView);
//overlays.add(myLocOverlay);
mapView.getOverlays().add(myLocOverlay);
myLocOverlay.enableMyLocation();
myLocOverlay.runOnFirstFix(new Runnable() {
public void run() {
mc.animateTo(myLocOverlay.getMyLocation());
}
});
mc.setZoom(15);
mapView.invalidate();
}
}
I gave essential permissions and I use google maps library
