Android: download .html and convert it to String

Question

I need to download .html file from some URL. How can I do it? And how can I convert it to String?

UPDATED:

I have no idea why you downvoting. I can get the desired result on iOS by only using one method stringWithContentsOfURL:encoding:error:. And I suggested that Android has similar. method

Code below downloads html page from link, and return html page converted to string in completion callback

public class HTMLPageDownloader extends AsyncTask<Void, Void, String> {
    public static interface HTMLPageDownloaderListener {
        public abstract void completionCallBack(String html);
    }
    public HTMLPageDownloaderListener listener;
    public String link;
    public HTMLPageDownloader (String aLink, HTMLPageDownloaderListener aListener) {
        listener = aListener;
        link = aLink;
    }

    @Override
    protected String doInBackground(Void... params) {
        // TODO Auto-generated method stub
        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(link);
        String html = "";
        try {
            HttpResponse response = client.execute(request);
            InputStream in;
            in = response.getEntity().getContent();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(in));
            StringBuilder str = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                str.append(line);
            }
            in.close();
            html = str.toString();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return html;
    }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        if (!isCancelled()) {
            listener.completionCallBack(result);
        }
    }
}

How's this:

URL url;
InputStream is = null;
DataInputStream dis;
String line;
String out = "";


try {
    url = new URL("http://www.example.com/");
    is = url.openStream();  // throws an IOException
    dis = new DataInputStream(new BufferedInputStream(is));

    while ((line = dis.readLine()) != null) {
       out.append(line);
    }
  } catch (MalformedURLException mue) {
       mue.printStackTrace();
  } catch (IOException ioe) {
       ioe.printStackTrace();
 } finally {
     try {
        is.close();
      } catch (IOException ioe) {    
    }
      }
