Excepción de puntero nulo al instanciar la resolución de contenido?

En mi Android, estoy leyendo los contactos mediante resolución de contenido. Pero la resolución de contenido no se está inicializando, da NullPointerException . Quiero utilizar los arrays de cadenas en otra clase y para obtener valores en ellos tengo que consultar la base de datos y leer los contactos del teléfono, pero se quedó con esa excepción como se señala en el código:

 //this code is in some other class... et= (EditText) findViewById(R.id.searchcontact); et.addTextChangedListener(new TextWatcher() { public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub lva.getFilter().filter(s); RefreshListView rlv=new RefreshListView();<----class is getting called from here lva.notifyDataSetInvalidated(); lva = new ListViewAdapterContacts(AllContactsActivity.this, rlv.names, rlv.types, rlv.phones, rlv.ids); lv.setAdapter(lva); } public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } public void afterTextChanged(Editable s) { // TODO Auto-generated method stub // lva.notifyDataSetChanged(); } }); ...............********......... public class RefreshListView extends ListActivity{ String[] names,phones,types,ids; String name,id,phoneNumber; int type; ArrayList <String> newValues; public void onCreate(Bundle b){ super.onCreate(b); newValues=SetNewList.getNames(); getContacts(); } public void getContacts(){ int foo = 0; ContentResolver cr = getContentResolver();<---//null pointer exception Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC"); if (cur.getCount() > 0) { names = new String[cur.getCount()]; phones = new String[cur.getCount()]; types = new String[cur.getCount()]; ids = new String[cur.getCount()]; while (cur.moveToNext()) { name = cur .getString(cur .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); for(int i=0;i<=newValues.size();i++){ if(newValues.get(i).equalsIgnoreCase(name)) { id = cur.getString(cur .getColumnIndex(ContactsContract.Contacts._ID)); String hasPhone = cur .getString(cur .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); if (Integer.parseInt(hasPhone) == 1) { Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + id, null, null); while (phones.moveToNext()) { phoneNumber = phones .getString(phones .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); type = phones.getInt(phones.getColumnIndex(Phone.TYPE)); } // while phones.close(); }// if else { phoneNumber = "unknown"; type = 0; }// else phones[foo] = phoneNumber; names[foo] = name; ids[foo] = id; if (type == 0) { String value = "unknown"; types[foo] = value; } else if (type == 1) { String value = "home"; types[foo] = value; }// if else if (type == 2) { String value = "mobile"; types[foo] = value; }// else if else if (type == 3) { String value = "Work"; types[foo] = value; } else if (type == 4) { String value = "Workfax"; types[foo] = value; } else if (type == 5) { String value = "Home Fax"; types[foo] = value; } else if (type == 6) { String value = "Pager"; types[foo] = value; } else { String value = "Other"; types[foo] = value; } foo++; } } }// while }// if }// get contacts }
