I cant see map ın the screen.Markers are seen but not map?

import java.util.List; import android.content.Intent; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.util.Log; import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.Overlay; import com.google.android.maps.OverlayItem; public class PlacesMapActivity extends MapActivity { // Nearest places PlacesList nearPlaces; // Map view MapView mapView; // Map overlay items List<Overlay> mapOverlays; AddItemizedOverlay itemizedOverlay; GeoPoint geoPoint; // Map controllers MapController mc; double latitude; double longitude; OverlayItem overlayitem; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.map_places); // Getting intent data Intent i = getIntent(); // Users current geo location String user_latitude = i.getStringExtra("user_latitude"); String user_longitude = i.getStringExtra("user_longitude"); // Nearplaces list nearPlaces = (PlacesList) i.getSerializableExtra("near_places"); mapView = (MapView) findViewById(R.id.mapView); mapView.setBuiltInZoomControls(true); mapOverlays = mapView.getOverlays(); // Geopoint to place on map geoPoint = new GeoPoint((int) (Double.parseDouble(user_latitude) * 1E6), (int) (Double.parseDouble(user_longitude) * 1E6)); // Drawable marker icon Drawable drawable_user = this.getResources() .getDrawable(R.drawable.mark_red); itemizedOverlay = new AddItemizedOverlay(drawable_user, this); // Map overlay item overlayitem = new OverlayItem(geoPoint, "Your Location", "That is you!"); itemizedOverlay.addOverlay(overlayitem); mapOverlays.add(itemizedOverlay); itemizedOverlay.populateNow(); // Drawable marker icon Drawable drawable = this.getResources() .getDrawable(R.drawable.mark_blue); itemizedOverlay = new AddItemizedOverlay(drawable, this); mc = mapView.getController(); // These values are used to get map boundary area // The area where you can see all the markers on screen int minLat = Integer.MAX_VALUE; int minLong = Integer.MAX_VALUE; int maxLat = Integer.MIN_VALUE; int maxLong = Integer.MIN_VALUE; // check for null in case it is null if (nearPlaces.results != null) { // loop through all the places for (Place place : nearPlaces.results) { latitude = place.geometry.location.lat; // latitude longitude = place.geometry.location.lng; // longitude // Geopoint to place on map geoPoint = new GeoPoint((int) (latitude * 1E6), (int) (longitude * 1E6)); // Map overlay item overlayitem = new OverlayItem(geoPoint, place.name, place.vicinity); itemizedOverlay.addOverlay(overlayitem); // calculating map boundary area minLat = (int) Math.min( geoPoint.getLatitudeE6(), minLat ); minLong = (int) Math.min( geoPoint.getLongitudeE6(), minLong); maxLat = (int) Math.max( geoPoint.getLatitudeE6(), maxLat ); maxLong = (int) Math.max( geoPoint.getLongitudeE6(), maxLong ); } mapOverlays.add(itemizedOverlay); // showing all overlay items itemizedOverlay.populateNow(); } // Adjusting the zoom level so that you can see all the markers on map mapView.getController().zoomToSpan(Math.abs( minLat - maxLat ), Math.abs( minLong - maxLong )); // Showing the center of the map mc.animateTo(new GeoPoint((maxLat + minLat)/2, (maxLong + minLong)/2 )); mapView.postInvalidate(); } @Override protected boolean isRouteDisplayed() { return false; } }

My problem is map doesn't display on screen. Apis are opened, key was taken, I have given permissions in the manifest . Problem may be mapView but i couldn't solve it. Where can the problem be?

Thanks for your helps
