    ContentResolver cr = getContentResolver();
     Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
    null, null, null);
  String id = null, name = null, email = null, phone = null, note = null, orgName =     null, title = null;
  String Phone1 = "unknown", Phone2 = "unknown", Phone3 = "unknown", type1 = "unknown",        type2 = "unknown", type3 = "unknown";
  int size = cur.getCount();
if (cur.getCount() > 0) {
    int cnt = 1;
    while (cur.moveToNext())
    {
        email = "";
        name = "";
        cnt++;
        id = cur.getString(cur
                .getColumnIndex(ContactsContract.Contacts._ID));
        name = cur
                .getString(cur
