JSoup parsed elements empty

Question

I am trying to parse some data using JSoup, this is all happening in a asynctask (doInBackground) part of my MainActivity. Unfortunately all the elements (9) are empty when I execute the app.

When I debug below codeline, I actually get the complete website, it`s all there. The method readMultipleLinesRespone() is located in another class HttpUtility where I also call my Post and Get requests.

I tested this upfront by saving the website as a file and using JSoups assets ability, it worked perfectly then.

The setupAdapter() method in onPostExecute fills a ExpandableListview with data, should this info be nessecary. If you need more info pls ask.

Can somebody assist and tell me what I am doing wrong?

response1 = util.readMultipleLinesRespone(); <--- debugged and all data (seems) to be there but isn`t.

Edit: If I print response1, there is indeed no data to parse. Logcat output:

E/Resonse:: [Ljava.lang.String;@3d3410a

Below is the method readMultipleLinesRespone from HttpUtility class:

public String[] readMultipleLinesRespone() throws IOException {
    InputStream inputStream = null;
    if (httpConn != null) {
        inputStream = httpConn.getInputStream();
    } else {
        throw new IOException("Connection is not established.");
    }

    BufferedReader reader = new BufferedReader(new InputStreamReader(
            inputStream));
    List<String> response = new ArrayList<String>();

    String line = "";
    while ((line = reader.readLine()) != null) {
        response.add(line);
    }
    reader.close();

    return (String[]) response.toArray(new String[0]);
}

The asynctask where it`s all hapening:

private class FetchWebsiteData extends AsyncTask<Void, Void, Void> {
    ProgressDialog mProgressDialog;

    @Override
    protected void onPreExecute() {
        this.mProgressDialog = new ProgressDialog(getActivity());
        mProgressDialog.setMessage("Laden...");
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.show();
    }

    @Override
    protected Void doInBackground(Void... result) {

        try {
            util.sendGetRequest("https://mobile.somesite.nl/Data", null);
            response1 = util.readMultipleLinesRespone();
        } catch (IOException e) {
            e.printStackTrace();
        }

        if (response1.length > 0) {
            Document doc = Jsoup.parse(response1.toString());

            // Get the html document title
            Elements els = doc.select("span[class=item-value pull-right]");

                if (els.size() > 0) {
                    fac_naam = els.get(0).text();
                    fac_straat = els.get(1).text();
                    fac_post = els.get(2).text();
                    con_tel = els.get(3).text();
                    con_email = els.get(4).text();
                    betaal_reknr = els.get(5).text();
                    betaal_houd = els.get(6).text();
                    zig_gebruiker = els.get(7).text();
                    zig_wacht = els.get(8).text();
                }
        }
        return null;
        }

    @Override
    protected void onPostExecute(Void result) {
        super.onPreExecute();
        setupAdapter();
        mProgressDialog.dismiss();
    }
}

Answer 1

In the meantime I solved the problem. I did not pass the response string correctly to the asynctask which parses the required elements. Just required a public string in which the response is being set and passed (not an elegant way but it works):

public static String HttpResponse = "";

In the HttpUtility class:

public String[] readMultipleLinesRespone() throws IOException {
        ...

        TabFragment1.HttpResponse = response.toString();
     ...
        return (String[]) response.toArray(new String[0]);
    }

Then pass it to the asynctask:

@Override
        protected Void doInBackground(Void... result) {

            try {
                util.sendGetRequest(LoginActivity.PersData_URL, null);

                util.readMultipleLinesRespone();

            } catch (IOException e) {
                e.printStackTrace();
            }

            if (HttpResponse.length() > 0) {
                Document doc = Jsoup.parse(HttpResponse.toString());
                // Get the html document title
                Elements els = doc.select("span[class=item-value pull-right]");
              ...

            }
            return null;
        }
