How to capture map from mapView and save as image without using camera in Android?

Question

I am searching about how to save the image of map from mapview. But still found nothing. I used the below code but I still got the error of "Unable to start Activity... NullPointer Exception".

I am stuck on this query. Has anyone managed to do this?

    mapView.setWillNotCacheDrawing(false);
    mapView.destroyDrawingCache();
    mapView.buildDrawingCache();

    // Copy the drawing cache before the system recycles it
    Bitmap cachedImage = Bitmap.createBitmap(mapView.getDrawingCache());

    Bitmap bmap = Bitmap.createBitmap(mapView.getWidth(), mapView.getHeight(),
                                Bitmap.Config.ARGB_8888);
        Canvas offscreencanvas = new Canvas(bmap);
        offscreencanvas.drawBitmap(cachedImage, 0, 0, null);

void snapshot (GoogleMap.SnapshotReadyCallback callback) method was already added to GoogleMap API. You should use it. buildDrawingCache doesn't work for MapView cause map itself is rendering on SurfaceView which doesn't use View's drawing cache.
