        //HttpURLConnection httpConnection = (HttpURLConnection)connection;
        //InputStream in = httpConnection.getInputStream();
        SAXParserFactory saxparser = SAXParserFactory.newInstance();
        SAXParser parser = saxparser.newSAXParser();
        XMLReader xmlReader = parser.getXMLReader();
        XMLParser pc = new XMLParser();
        xmlReader.setContentHandler(pc);
        //InputStream is = getAssets().open("propinsi_17_1.xml");
        //InputStream is = new URL(URL_MAIN).openStream();
        xmlReader.parse(new InputSource(connection.getInputStream()));
        BindingData bindingData = new BindingData(this, pc.kota, pc.cuaca, pc.suhuMin, pc.suhuMax, pc.kelembapanMin, pc.kelembapanMax, pc.kecepatanAngin, pc.arahAngin);
        listView.setAdapter(bindingData);
    } 
    catch (Exception e) {
        e.getMessage();
    }
}

}

I think the problem only on this class, but i have no idea which one. Please help

many said that it is possible, check this http://www.androidpeople.com/android-xml-parsing-tutorial-using-saxparser — arya maharta, Aug 21 '14 at 07:42
first of all Your directly using local host that will not work. Use `10.0.2.2` instead of localhost then check. for more detail visit here : http://stackoverflow.com/questions/6760585/accessing-localhostport-from-android-emulator — Shabbir Dhangot, Aug 21 '14 at 07:48

It might be android.os.NetworkOnMainThreadException - you're trying to do time-heavy task in a UI thread and the system is preventing you from doing it (you can possibly see this in your logcat). You can implement AsyncTask in order to do it in the background thread.

It may also be that you forgot to add the permission in a manifest file - <uses-permission android:name="android.permission.INTERNET" />
