我想从单个查询中获取名字、姓氏、电子邮件 ID 的 android 联系人详细信息。如果我通过以下过程获取联系人。获取和过滤需要花费大量时间。请给出解决方案来解决这个问题。目前我正在这样做。请查看下面的代码。

public static JSONArray getMABTosendServer(Context context, UserBean user,
        DatabaseUserManager userManager) throws JSONException {
    hashedEmails = new HashMap<String, AddressBean>();
    JSONArray jsonArray = new JSONArray();
    HashMap<String, String> emailValues = new HashMap<String, String>();

    StringBuffer sb = new StringBuffer();
    sb.append("......Contact Details.....");
    ContentResolver cr = context.getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
            null, null, null);
    String emailContact = "";
    String emailType = "";
    Cursor nameCursor = null;
    String firstName = "";
    String lastName = "";
    String id = null;
    long userLastContactId = 0;
    int i = 0;
    if (cur.getCount() > 0) {
        while (cur.moveToNext()) {
            i++;

            id = cur.getString(cur
                    .getColumnIndex(ContactsContract.Contacts._ID));
            if (user != null && user.getLastContactId() == null) {
                userLastContactId = 0;
            } else {
                userLastContactId = Long.parseLong(user.getLastContactId());
            }
