Need to parse image src from HTML page then display it

Question

I\'m currently trying to develop an app whereby it visits the following site (Http://lulpix.com) and parses the HTML and gets the img src from the following section

Answer 1

Here's an AsyncTask that connects to lulpix, fakes a referrer & user-agent (lulpix tries to block scraping with some pretty lame checks apparently). Starts like this in your Activity:

new ForTheLulz().execute();

The resulting Bitmap is downloaded in a pretty lame way (no caching or checks if the image is already DL:ed) & error handling is overall pretty non-existent - but the basic concept should be ok.

class ForTheLulz extends AsyncTask {
        @Override
        protected Bitmap doInBackground(Void... args) {
            Bitmap result = null;
            try {
                Document doc = Jsoup.connect("http://lulpix.com")
                        .referrer("http://www.google.com")
                        .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                        .get();
                        //parse("http://lulpix.com");
                if (doc != null) {
                    Elements elems = doc.getElementsByAttributeValue("class", "pic rounded-8");
                    if (elems != null && !elems.isEmpty()) {
                        Element elem = elems.first();
                        elems = elem.getElementsByTag("img");
                        if (elems != null && !elems.isEmpty()) {
                            elem = elems.first();
                            String src = elem.attr("src");
                            if (src != null) {
                                    URL url = new URL(src);
                                    // Just assuming that "src" isn't a relative URL is probably stupid.
                                    InputStream is = url.openStream();
                                    try {
                                        result = BitmapFactory.decodeStream(is);
                                    } finally {
                                        is.close();
                                    }
                            }
                        }
                    }
                }
            } catch (IOException e) {
                // Error handling goes here
            }
            return result;
        }
        @Override
        protected void onPostExecute(Bitmap result) {
            ImageView lulz = (ImageView) findViewById(R.id.lulpix);
            if (result != null) {
                lulz.setImageBitmap(result);
            } else {
                //Your fallback drawable resource goes here
                //lulz.setImageResource(R.drawable.nolulzwherehad);
            }
        }
    }
