preciso de ajuda com Android

A essência do problema é que existe um layout no qual o analisador SAX executa e extrai essas taxas de câmbio da Internet. quando eu o adiciono ao ListView o programa não inicia, mas quando eu o envio para o console há dados, por favor me ajude a descobrir onde está o erro. (Amostra XML para ListView criou este my_list_items_currensy)

 public class ShowAllActivity extends AppCompatActivity { private ArrayList
  finalList; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list_layout); SAXParserFactory saxParserFactory = SAXParserFactory.newInstance(); try { URL url = new URL("http://resources.finance.ua/ua/public/currency-cash.xml"); InputStream stream = url.openStream(); SAXParser saxParser = saxParserFactory.newSAXParser(); // creating a SAX parser Handler handler = new Handler(); saxParser.parse(stream,handler); // here we parse our resource finalList = handler.getListOfAllCurrencies(); } catch (ParserConfigurationException e) { e.printStackTrace(); } catch (SAXException e) { e.printStackTrace(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } adapterList(); } public void adapterList(){ ArrayAdapter
  
   arrayAdapter = new ListOfAllCurrency(); ListView listView=(ListView)findViewById(R.id.c_list); listView.setAdapter(arrayAdapter); } public class ListOfAllCurrency extends ArrayAdapter
   
    { public ListOfAllCurrency() { super(ShowAllActivity.this,R.layout.my_list_items_currensy,finalList); } @Override public View getView(int position, View convertView, ViewGroup parent) { View view = convertView; if( view==null){ view = getLayoutInflater().inflate(R.layout.my_list_items_currensy,parent,false); } TextView bankName = (TextView)view.findViewById(R.id.bankName); TextView currency = (TextView)view.findViewById(R.id.currency); TextView bay = (TextView)view.findViewById(R.id.bay); TextView sell = (TextView)view.findViewById(R.id.sell); bankName.setText(finalList.get(position).getBankName()); StringBuilder itemsString = new StringBuilder(); int lengthListOfCurrency = finalList.get(position).getList().size(); for(int i=0;i
