I need to extract web page source to string in Android. I tried to do it using HttpClient, HttpGet and HttpResponse, but this method doesn't work. I have to do try/catch to every initialization of this methods and anyway, the application force closes.

```
  public static String getHtmlSource(String webPage){
            HttpClient client = new DefaultHttpClient();
            URI url = null;
            try {
                url = new URI("http://www.kinopoisk.ru/film/581493");
            } catch (URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            HttpGet request = new HttpGet(url);
            HttpResponse response = null;
            try {
                response = client.execute(request);
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            String html = "";
            InputStream in = null;
            try {
                in = response.getEntity().getContent();
            } catch (IllegalStateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            BufferedReader reader = new BufferedReader(new InputStreamReader(in));
            StringBuilder str = new StringBuilder();
            String line = null;
            try {
                while((line = reader.readLine()) != null)
                {
                    str.append(line);
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            try {
                in.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            html = str.toString();
            return html;
        }
