```

The error occurs in my code at this point:

```
        gs.setSelectedAccount(gs.getAccounts()[position]);

```

Here position gives the correct value but the error persists.

Here is the Code:

```
public class ContactListView extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) 
{
  super.onCreate(savedInstanceState);

  GlobalState gs = (GlobalState) getApplication();

  setContentView(R.layout.newlist);

  getAccountData();
  setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, gs.getAccountNames()));

  ListView lv = getListView();
  lv.setTextFilterEnabled(true);

  final EditText et = (EditText) findViewById(R.id.editText);

  lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
        GlobalState gs = (GlobalState) getApplication();
        try{
        gs.setSelectedAccount(gs.getAccounts()[position]);
        }catch(IndexOutOfBoundsException e)
        {
            e.printStackTrace();
        }
        JSONObject acct = gs.getSelectedAccount();
        String str = null;
        try {
            str = acct.getString("AccountId")!= "null"?acct.getString("AccountId"):"";
        } catch (JSONException e1) {

            e1.printStackTrace();
        }
            launchAccountDetail(str);
      // When clicked, show a toast with the TextView text
      Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
          Toast.LENGTH_SHORT).show();
    }
  });
