android.content.res.Resources$NotFoundException: String resource ID #0x1

i'm trying to create an app for reading RSS feeds. I already have an activity with different tabs for each RSS feed. Now i'm trying to actually read the RSS feed using DomParser.class and HttpReader.class but i'm getting an error..

HttpReader.java

public class HttpReader extends AsyncTask<String, Void, String> {
public HttpReader() {

}

public interface OnResultReadyListener {
    public void resultReady(String result);
}

private OnResultReadyListener onResultReadyListener;

public void setOnResultReadyListener(OnResultReadyListener listener) {
    onResultReadyListener = listener;
}

@Override
protected String doInBackground(String... urls){
    return getTextFromUrl(urls[0]);
}

@Override
protected void onPostExecute(String result) {
    onResultReadyListener.resultReady(result);
}

private String getTextFromUrl(String url) {
    String text = null;

    try
    {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(url);

        HttpResponse httpResponse = httpClient.execute(httpGet);
        HttpEntity httpEntity = httpResponse.getEntity();
        text = EntityUtils.toString(httpEntity);

    } catch (UnsupportedEncodingException e) {
        Log.e("Error: ", e.getMessage());
    } catch (ClientProtocolException e) {
        Log.e("Error: ", e.getMessage());
    } catch (IOException e) {
        Log.e("Error: ", e.getMessage());
    }

    return text;

}
}

DomParser.java

public class DomParser {

private Document doc = null;

public DomParser() {
}

public void buildDocument(String newXml) {
    String xml = newXml.replaceAll(">\\s+<", "><").trim();
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

    try {
        DocumentBuilder db = dbf.newDocumentBuilder();

        InputSource is = new InputSource();
        is.setCharacterStream(new StringReader(xml));
        doc = db.parse(is);

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

onCreateView from PlaceholderFragment

There goes something wrong when i'm trying to execute httpReader.. newsfeed.getUrl() returns a String

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
  --> THIS IS LINE 197
        Bundle args = getArguments();
        Newsfeed newsfeed = db.getNewsfeed(args.getInt(ARG_SECTION_NUMBER));

        HttpReader httpReader = new HttpReader();
        httpReader.setOnResultReadyListener(new HttpReader.OnResultReadyListener() {
            @Override
            public void resultReady(String result) {
                domParser.buildDocument(result);
            }
        });

        httpReader.execute(newsfeed.getUrl());

        return rootView;
    }
