threadid = 1 잡히지 않는 예외 (그룹 = 0x410702a0)로 끝나는 스레드

Question

나는 안드로이드 응용 프로그램을 개발하고 모든 것이 올바르지 만 오류는 아니지만 코드를 실행할 때 아래에서이 오류를 발견하고 코드를 추적하면이 줄에 멈 춥니 다 :

HttpResponse httpResponse = httpClient.execute(httpPost); 

코드의 일부 :

try { 
     // defaultHttpClient 

     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 
     httpPost.setEntity(new UrlEncodedFormEntity(params)); 
     Log.d("w", "2a json..................."); 
     HttpResponse httpResponse = httpClient.execute(httpPost); 
     Log.d("w", "2b json..................."); 
     HttpEntity httpEntity = httpResponse.getEntity(); 
     Log.d("w", "2c json..................."); 
     is = httpEntity.getContent(); 
     Log.d("w", "3 json..................."); 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

오류 :

threadid=1: thread exiting with uncaught exception (group=0x410702a0)

이 만들기 N AsyncTask를하고 doInBackground 메소드 내부 네트워크 호출이 여기

이 코드 할

class ABCTask extends AsyncTask<String, Void, Void> { 

    private Exception exception; 

    protected void doInBackground(String... urls) { 
     try { 
     // defaultHttpClient 

     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 
     httpPost.setEntity(new UrlEncodedFormEntity(params)); 
     Log.d("w", "2a json..................."); 
     HttpResponse httpResponse = httpClient.execute(httpPost); 
     Log.d("w", "2b json..................."); 
     HttpEntity httpEntity = httpResponse.getEntity(); 
     Log.d("w", "2c json..................."); 
     is = httpEntity.getContent(); 
     Log.d("w", "3 json..................."); 
    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    } 

    protected void onPostExecute() { 

// write what u want to do after completion of the doInBackground method 
    } 
} 

new ABCTask().execute();
