Question

I have captured a screenshot of my current location from a mapview and import it to my application frm sd card.I integrated the map using a map view.So wen my application is ran and when the map is loaded some square boxes are coming in my map.after capturing the image.when open the image that crsses are coming.why its happening like that.anyone has an idea.my sample screen shot and code is mentioned below.

            ![public void onClick(View v) {
            getMapImage();
            saveMapImage();

            }
        });

        // enable Street view by default
        mapView.setStreetView(true);

        // enable to show Satellite view
        // mapView.setSatellite(true);

        // enable to show Traffic on map
        // mapView.setTraffic(true);
        mapView.setBuiltInZoomControls(true);

        mapController = mapView.getController();
        mapController.setZoom(16); 
    }
    private Bitmap getMapImage() {  
        /* Position map for output */  
        MapController mc = mapView.getController();  
//        mc.setCenter(SOME_POINT);  
        mc.setZoom(16);  

        /* Capture drawing cache as bitmap */  
        mapView.setDrawingCacheEnabled(true);  
        Bitmap bmp = Bitmap.createBitmap(mapView.getDrawingCache());  
        mapView.setDrawingCacheEnabled(false);  

        return bmp;

Answer 1

may you try mapView.setStreetView(false); , I once had the same issue and found out that it was because of setting the street view with true.
