Why isn't ListView from BroadcastReceiver updated?

Question

Android

I have this code:

public class AddNewRequestActivity extends Activity {
    ListView lvMain;
    ArrayAdapter<String> adapter;
    String[] names = {"Денис", "Андрей"}; //допустим, какие-то начальные данные
    protected void onCreate(Bundle savedInstanceState) {
        lvMain = (ListView) findViewById(R.id.listViewRequests);
        adapter = new ArrayAdapter<String>(AddNewRequestActivity.this, android.R.layout.simple_list_item_1, names);
        lvMain.setAdapter(adapter);
        br = new BroadcastReceiver() {
            public void onReceive(Context context, Intent intent) {
               String[] newNames = { "Иван", "Марья", "Петр", "Антон", "Даша", "Борис", "Костя", "Игорь", "Анна", "Денис", "Андрей" };
               adapter.clear();
               adapter.addAll(newNames);
               adapter.notifyDataSetChanged();
            }
        };
        IntentFilter intFilt = new IntentFilter(BROADCAST_ACTION);
        registerReceiver(br, intFilt);
    }
}

but after the onReceive is triggered in the Listview, only "Denis", "Andrey" are displayed, i.e. ListView is not updating. what's wrong?
