How to resolve java.io.FileNotFoundException?

Question

I'm trying retrieve artists photos for all music using the last.fm api but I got java.io.FileNotFoundException and I don't know why.

Here is my code

protected Bitmap doInBackground(String... strings) {
        Bitmap bmp;
        try {
            Connection connection = Jsoup.connect(mArtisName).ignoreContentType(true).ignoreHttpErrors(true);
            Connection.Response resp = connection.execute();
            Document document;
            if (resp.statusCode() ==200) {
                document = connection.parser(Parser.xmlParser()).post();
                mArtisName = document.select("image[size=extralarge]").text();
            }
            bmp = cache.get(Artis);
            if (bmp==null) {
                URL url = new URL(mArtisName);
                URLConnection update = url.openConnection();
                bmp = BitmapFactory.decodeStream(update.getInputStream());
                cache.put(Artis, bmp);
            }
        } catch (Exception ex) {
            ex.printStackTrace();
            bmp = defaultBitmap;
        }
        return bmp;
    }

I think what you are requesting doesn't exist. In fact, your code may hit a 404 error. The URL class indicates this type of error with a java.io.FileNotFoundException.

On the other hand, make sure that the CSS selector image[size=extralarge] returns exactly one image. Be aware also that the following line will return the cumulative text of all elements selected.

document.select("image[size=extralarge]").text()
