서버내 파일리스트를 spinner로 불러오려합니다.

Question

php

    function getPath1List() {
        $dir='00';
        $files = scandir($dir);
        $file_path1 = array();
        $file_path1["categories"] = array();
        
        foreach($files as $ind_file) {
            $tmp = array();
            $tmp["filePath1"] = $ind_file;
            
            array_push($file_path1["categories"], $tmp);
        }
        
        header('Content-Type: application/json');
    
        echo json_encode($file_path1);
    }
    getPath1List();

결과값은

{"categories":[{"filePath1":"."},{"filePath1":".."},{"filePath1":"2016_04_20"},{"filePath1":"2016_04_21"},{"filePath1":"2016_04_22"},{"filePath1":"2016_04_23"},{"filePath1":"2016_04_24"},{"filePath1":"2016_04_25"},{"filePath1":"2016_04_26"}
android에서 데이터값을 받아오기위해서 사용한 util은

get & set 용

public class Category {

    private String filePath1;

    public Category(){}
    public Category(String filePath1) {
        this.filePath1 = filePath1;
    }

    public String getFilePath1() {
        return filePath1;
    }

    public void setFilePath1(String filePath1) {
        this.filePath1 = filePath1;
    }
}

유틸

public class ServiceHandler {

   static InputStream is = null;
   static String file_path1 = null;
   public final static int GET = 1;
   public final static int POST = 2;

   public ServiceHandler() {

   }
   public String makeServiceCall(String url, int method) {
       return this.makeServiceCall(url, method, null);
   }
   public String makeServiceCall(String url, int method,
           List<NameValuePair> params) {
       try {
           // http client
           DefaultHttpClient httpClient = new DefaultHttpClient();
           HttpEntity httpEntity = null;
           HttpResponse httpResponse = null;
            
           // Checking http request method type
           if (method == POST) {
               HttpPost httpPost = new HttpPost(url);
               // adding post params
               if (params != null) {
                   httpPost.setEntity(new UrlEncodedFormEntity(params));
               }

               httpResponse = httpClient.execute(httpPost);

           } else if (method == GET) {
               // appending params to url
               if (params != null) {
                   String paramString = URLEncodedUtils
                           .format(params, "utf-8");
                   url += "?" + paramString;
               }
               HttpGet httpGet = new HttpGet(url);

               httpResponse = httpClient.execute(httpGet);

           }
           httpEntity = httpResponse.getEntity();
           is = httpEntity.getContent();

       } catch (UnsupportedEncodingException e) {
           e.printStackTrace();
       } catch (ClientProtocolException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       }

       try {
           BufferedReader reader = new BufferedReader(new InputStreamReader(
                   is, "UTF-8"), 8);
           StringBuilder sb = new StringBuilder();
           String line = null;
           while ((line = reader.readLine()) != null) {
               sb.append(line + "\n");
           }
           is.close();
           file_path1 = sb.toString();
       } catch (Exception e) {
           Log.e("Buffer Error", "Error: " + e.toString());
       }

       return file_path1;

   }
}
