Loading and parsing XML in Android

You need to download and parse XML. Uploading HttpURLConnection , parsing XmlPullParser . It seems that the answer is an empty document (no error). I did the same with other links - everything worked.

Load and parse code

 import org.xmlpull.v1.XmlPullParser; import org.xmlpull.v1.XmlPullParserFactory; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import java.util.ArrayList; import java.util.HashMap; import java.util.Map; /** * Created by MaZ on 30.05.2016. */ public class ZaprosParsTask extends AsyncTask<ArrayList<String>, Void, ArrayList<String>> { private MainActivity activity; private String url; private XmlPullParserFactory xmlFactoryObject; private ProgressDialog pDialog1; public static ArrayList<String> list_products = new ArrayList<String>(); static Map<String, String> map = new HashMap<String, String>(); public ZaprosParsTask(MainActivity activity, String url) { this.activity = activity; this.url = url; } @Override protected void onPreExecute() { super.onPreExecute(); pDialog1 = new ProgressDialog(activity); pDialog1.setMessage("Загрузка..."); pDialog1.show(); } @Override protected ArrayList<String> doInBackground(ArrayList<String>... params) { try { URL url = new URL(this.url); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setReadTimeout(10000 /* milliseconds */); connection.setConnectTimeout(15000 /* milliseconds */); connection.setRequestMethod("GET"); connection.setDoInput(true); connection.connect(); InputStream stream = connection.getInputStream(); xmlFactoryObject = XmlPullParserFactory.newInstance(); XmlPullParser parser = xmlFactoryObject.newPullParser(); parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false); parser.setInput(stream, null); ArrayList<String> list_products = (ArrayList<String>) parseXML(parser); stream.close(); return list_products; } catch (Exception e) { e.printStackTrace(); Toast.makeText(activity, "Нет подключения к интернету.", Toast.LENGTH_SHORT) .show(); return null; } } public ArrayList<String> parseXML(XmlPullParser parser) { try { while (parser.getEventType() != XmlPullParser.END_DOCUMENT) { if (parser.getEventType() == XmlPullParser.START_TAG && parser.getName().equals("products")) { if (parser.getEventType() == XmlPullParser.START_TAG && parser.getName().equals("product")) { String id = parser.getAttributeValue(0); String name = parser.getAttributeValue(1); String form = parser.getAttributeValue(2); String producer = parser.getAttributeValue(5); list_products.add(name + "\n" + form + "\n" + producer); } } parser.next(); } } catch (Exception e) { e.printStackTrace(); Toast.makeText(activity, "Нет подключения к интернету.", Toast.LENGTH_SHORT) .show(); } return list_products; } @Override protected void onPostExecute(ArrayList<String> list_products) { super.onPostExecute(list_products); pDialog1.dismiss(); } } 

Main

 public class MainActivity extends AppCompatActivity implements View.OnClickListener { Button btnGippokrat; Button btnPerson; Button btnRegion; Button btnSearch; private final static String url = "http://api.gippokrat.by/get/?city=141&zapros=АСПИРИН&type=xml&key=MUUdeHa4592liK134HE06vq23&%20geo_d=27.5667&geo_sh=53.9&radius=10"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); new ZaprosParsTask(this, url).execute(); btnGippokrat = (Button) findViewById(R.id.btnGippokrat); btnPerson = (Button) findViewById(R.id.btnPerson); btnRegion = (Button) findViewById(R.id.btnRegion); btnSearch = (Button) findViewById(R.id.btnSearch); btnRegion.setOnClickListener(this); btnGippokrat.setOnClickListener(this); btnPerson.setOnClickListener(this); btnSearch.setOnClickListener(this); } @Override public void onClick(View v) { // по id определеяем кнопку, вызвавшую этот обработчик switch (v.getId()) { case R.id.btnRegion: // break; case R.id.btnGippokrat: // break; case R.id.btnPerson: // break; case R.id.btnSearch: // кнопка поиска // break; } } } 

The result will be displayed in RecyclerView . Tell HttpURLConnection what could be the problem, maybe HttpURLConnection has any limitations on file size? What other method can this be done? Thank.
