UrlEncodedFormEntity发出错误

Question

我是Android的新手，我正在尝试对我的用户进行google +验证。当我尝试使用UrlEncodedFormEntity（）时，它说“构造函数UrlEncodedFormEntity（ArrayList []）未定义”。下面是代码，我不知道如何摆脱这个错误。

公共类Posting扩展了AsyncTask，Void，Void＆gt; {

@Override
protected Void doInBackground(ArrayList<NameValuePair>... nameValuePair) {


        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost("accounts.google.com");


     // Url Encoding the POST parameters
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
        } catch (UnsupportedEncodingException e) {
            // writing error to Log
            e.printStackTrace();
        }

        // Making HTTP Request
        try {
            HttpResponse response = httpClient.execute(httpPost);

            // writing response to log
            Log.d("Http Response:", response.toString());
        } catch (ClientProtocolException e) {
            // writing exception to log
            e.printStackTrace();
        } catch (IOException e) {
            // writing exception to log
            e.printStackTrace();

        }


    return null;
}

}
