NullPointer exception while try to draw a quite big polygon #551

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When I try to draw a quite big polygon that comes from a GeoJson, it crashes
With the smaller ones I have no problems if I turn off hardware accelation

This is my source code:

    private void inicializarMapa() {
        final DisplayMetrics dm = context.getResources().getDisplayMetrics();
        mResourceProxy = new ResourceProxyImpl(getActivity().getApplicationContext());

        mPrefs = context.getSharedPreferences(Constants.PREFS_NAME, Context.MODE_PRIVATE);

        mMapController = mMapView.getController();
        mMapController.setZoom(5);
        // only do static initialisation if needed
        if (CloudmadeUtil.getCloudmadeKey().length() == 0) {
            CloudmadeUtil.retrieveCloudmadeKey(context.getApplicationContext());
        }

        this.mCompassOverlay = new CompassOverlay(context, new InternalCompassOrientationProvider(context), mMapView);

        mScaleBarOverlay = new ScaleBarOverlay(context);
        mScaleBarOverlay.setCentred(true);
        mScaleBarOverlay.setScaleBarOffset(dm.widthPixels / 2, 10);

        mMapView.setBuiltInZoomControls(true);
        mMapView.setMultiTouchControls(true);

        mMapView.getOverlays().add(this.mCompassOverlay);

        mMapView.getController().setZoom(mPrefs.getInt(Constants.PREFS_ZOOM_LEVEL, 10));
        mMapView.scrollTo(mPrefs.getInt(Constants.PREFS_SCROLL_X, 0), mPrefs.getInt(Constants.PREFS_SCROLL_Y, 0));

        mCompassOverlay.enableCompass();

        geoJsonService = new GeoJsonService(MapaIncidenciasFrgmt.this);
        //I get the geoJson from a restfull service
        geoJsonService.execute();
    }

    public void stopWaitForGeoJsonResponse(boolean exito) {
        final KmlDocument kmlDocument = new KmlDocument();
        mLog.info(appContext.getGeoJson());
        kmlDocument.parseGeoJSON(appContext.getGeoJson());
        final FolderOverlay kmlOverlay = (FolderOverlay) kmlDocument.mKmlRoot.buildOverlay(mMapView, null, null,
                kmlDocument);
        mMapView.getOverlays().add(kmlOverlay);
        mMapView.invalidate();

        // mMapView.zoomToBoundingBox(kmlDocument.mKmlRoot.getBoundingBox());
    }

This is the exception trace:
