XML SAX Parser not working - NullPointerException
<p>the whole day I tried to figure out how to get my parser working, but for some reason I always get a NullPointerException, here is my code:</p>

<p><strong>MainActivity:</strong></p>

<pre><code>public class MainActivity extends Activity {
    XMLHandler data;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


try {
             Log.i("PARSER", "versuch!");

                /**
                 * Create a new instance of the SAX parser
                 **/

                SAXParserFactory saxPF = SAXParserFactory.newInstance();
                SAXParser saxP = saxPF.newSAXParser();
                XMLReader xmlR = saxP.getXMLReader();


                URL url = new URL("my xml file"); // URL of the XML

                /** 
                 * Create the Handler to handle each of the XML tags. 
                 **/
                 data = new XMLHandler();
                xmlR.setContentHandler(data);
                xmlR.parse(new InputSource(url.openStream()));


            } catch (Exception e) {
                System.out.println(e);
                Log.i("PARSER", "ES KLAPPT NICHT!");
            }




        TextView txt1 = (TextView) findViewById(R.id.txtview1);
        txt1.setText(data.getTournament().get(0).get(0).getTeam1().toString());
