Current location on map using WIFI in android - android-maps

Question

i just need to find the current location on maps using WIFI.I used tha below code to do that.
My code:
public class LocationActivity extends MapActivity implements LocationListener {
private MapView mapView;
private LocationManager locationManager;
private String latitude,longtitude;
#Override
protected boolean isRouteDisplayed() {
return false;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle bundle = this.getIntent().getExtras();
latitude = bundle.getString("latitude");
longtitude = bundle.getString("longtitude");
setContentView(R.layout.locationtab);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
locationIdentifier();
}
private void createMyLocOverlay(Double latitude, Double longtitude) {
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = this.getResources().getDrawable(
R.drawable.mylocation);
GeoPoint point = new GeoPoint((int) (latitude * 1E6),
(int) (longtitude * 1E6));
OverlayItem overlayitem = new OverlayItem(point, null, "You are here!");
MyLocationOverlay itemizedoverlay = new MyLocationOverlay(drawable,
this);
itemizedoverlay.addOverlay(overlayitem);
MyLocationOverlay overlayToRemove = null;
for (Overlay overlay : mapOverlays) {
if (overlay instanceof MyLocationOverlay) {
overlayToRemove = (MyLocationOverlay) overlay;
}
}
if (overlayToRemove != null) {
mapOverlays.remove(overlayToRemove);
}
mapOverlays.add(itemizedoverlay);
}
public void locationIdentifier() {
locationManager = (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);
String provider = locationManager.getBestProvider(criteria,true);
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
createMyLocOverlay(location.getLatitude(), location.getLongitude());
Toast.makeText(
this,
"Latitude : " + location.getLatitude() + " : Longtitude : "
+ location.getLongitude(), Toast.LENGTH_LONG)
.show();
} else {
Toast.makeText(this, "Latitude/Longtitude not found",
Toast.LENGTH_LONG).show();
}
}
#Override
public void onLocationChanged(Location location) {
if (location != null) {
createMyLocOverlay(location.getLatitude(), location.getLongitude());
Toast.makeText(
this,
"LocationChanged Latitude : " + location.getLatitude()
+ " Longtitude : " + location.getLongitude(),
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Location is null", Toast.LENGTH_LONG).show();
}
}
#Override
public void onProviderDisabled(String provider) {
Toast.makeText(this, "Disabled provider " + provider, Toast.LENGTH_LONG)
.show();
}
#Override
public void onProviderEnabled(String provider) {
Toast.makeText(this, "Enabled new provider " + provider,
Toast.LENGTH_LONG).show();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}
How could i check it on emulator whether its working or not.?

Answer 1

For now, It is not possible to simulate it using emulator because it is simply doesn't support it. As alternative, you may put a flag constant (e.g. DEBUG=false/true) then if DEBUG=true, use the constant location otherwise use WIFI location.
Or use location provider which can support IP Address location. Which you can use as alternative if DEBUG=true.
