Intent ServiceのサーバーからJsonの応答をアンドロイドで取得する方法は？

Question

IntentServicesを使用してサーバーにデータを投稿していますが、IntentServiceでjson形式の応答を取得する方法がわかりません。また、このIntentServiceがバックグラウンドであるかどうか、応答に基づいていくつかの操作を実行する方法を知ることができます。

public class CDealIntentService extends IntentService { 
private static final String s_szDealDetailUrl = "http://202.121.144.133:8080/ireward/rest/json/metallica/getDealDetailInJSON"; 
private static String s_szresult = ""; 
Context ctx; 
String m_szMobileNumber, m_szEncryptedPassword; 

/** 
* Creates an IntentService. Invoked by your subclass's constructor. 
* <p/> 
* // * @param name Used to name the worker thread, important only for debugging. 
*/ 
public CDealIntentService() { 
    super("CDealIntentService"); 
} 

@Override 
protected void onHandleIntent(Intent intent) { 
    Context ctx = getApplicationContext(); 
    CLoginSessionManagement m_oSessionManagement = new CLoginSessionManagement(ctx); 
    HashMap<String, String> user = m_oSessionManagement.getLoginDetails(); 
    m_szMobileNumber = user.get(CLoginSessionManagement.s_szKEY_MOBILE);// getting mobile from saved preferences.......... 
    m_szEncryptedPassword = user.get(CLoginSessionManagement.s_szKEY_PASSWORD);// getting password from shared preferences... 

    InputStream inputStream; 
    try { 
     // 1. create HttpClient 
     HttpClient httpclient = new DefaultHttpClient(); 
     // 2. make POST request to the given URL 
     HttpPost httpPost = new HttpPost(s_szDealDetailUrl); 
     String json; 
     // 3. build jsonObject 
     JSONObject jsonObject = new JSONObject(); 
     jsonObject.put("agentCode", m_szMobileNumber);// mobile Number 
     jsonObject.put("pin", m_szEncryptedPassword);// password 
     //noinspection AccessStaticViaInstance 
     jsonObject.put("dealcode", CDealCode.getInstance().getS_szDealCode());// dealCode 
     // 4. convert JSONObject to JSON to String 
     json = jsonObject.toString(); 
     // 5. set json to StringEntity 
     StringEntity se = new StringEntity(json); 
     // 6. set httpPost Entity 
     httpPost.setEntity(se); 
     // 7. Set some headers to inform server about the type of the content 
     // httpPost.setHeader("Accept", "application/json"); ///not required 
     httpPost.setHeader("Content-type", "application/json"); 
     // 8. Execute POST request to the given URL 
     HttpResponse httpResponse = httpclient.execute(httpPost); 
     HttpEntity entity = httpResponse.getEntity(); 
     // 9. receive response as inputStream 
     inputStream = entity.getContent(); 
     System.out.print("InputStream...." + inputStream.toString()); 
     System.out.print("Response...." + httpResponse.toString()); 

     StatusLine statusLine = httpResponse.getStatusLine(); 
     System.out.print("statusLine......" + statusLine.toString()); 
     ////Log.d("resp_body", resp_body.toString()); 
     int statusCode = statusLine.getStatusCode(); 
     if (statusCode == 200) { 
      // 10. convert inputstream to string 
      s_szresult = CJsonsResponse.convertInputStreamToString(inputStream); 
     } else 
      s_szresult = "Did not work!"; 

    } catch (Exception e) { 
     Log.d("InputStream", e.getLocalizedMessage()); 
    } 

    System.out.println("Result" + s_szresult); 
} 

}

コードの下の使用、

if (statusCode == 200) { 

    String jsonString = EntityUtils.toString(httpResponse.getEntity()); 

    JSONObject jsonObj = new JSONObject(jsonString); 

    // Do operation on jsonObj 
}
