youtube Json - C error

Question

나는 응용 프로그램이 중지되었지만 오류가 발생하지 않았습니다. YouTube 제목에서 arraylist를 채우고 싶습니다 .JTube 데이터를 구문 분석하고 싶지만 프로그램이 중지되었습니다. 어떻게 해결할 수 있습니까? 뭔가 잘못 됐어? 왜 jsonc를 사용하는

feedUrl="https://gdata.youtube.com/feeds/api/users/muyap/uploads?v=2&alt=jsonc&max-results=2"; 

HttpClient client = new DefaultHttpClient(); 
HttpGet getRequest = new HttpGet(feedUrl); 
HttpResponse responce; 
try { 
    responce = client.execute(getRequest); 
    StatusLine statusLine = responce.getStatusLine(); 
    int statusCode = statusLine.getStatusCode(); 
    if(statusCode!=200) 
    { 

     Toast.makeText(YouTube.this, "Yükleme Gerçekleşmedi", Toast.LENGTH_LONG).show(); 

    }else{ 
    InputStream JsonStream=responce.getEntity().getContent(); 
    BufferedReader reader= new BufferedReader(new InputStreamReader(JsonStream)); 
    StringBuilder builder = new StringBuilder(); 
    String line; 
    while((line=reader.readLine())!=null) 
    { 

     builder.append(line); 
    } 
    String JSONdata = builder.toString(); 
    Log.i("JsonData",JSONdata); 
    JSONObject json = new JSONObject(JSONdata); 
    JSONObject data = json.getJSONObject("data"); 
    JSONArray items=data.getJSONArray("items"); 

    for(int i=0;i<items.length();i++) 
    { 

     JSONObject video=items.getJSONObject(i); 
     videoArrayList.add(video.getString("title")); 

    } 

    list = (ListView)findViewById(R.id.listView1); 
    list.setAdapter(new ArrayAdapter<String>(YouTube.this, android.R.layout.simple_list_item_1,videoArrayList)); 

    } 
} catch (ClientProtocolException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} catch (IOException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} catch (JSONException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
}

...이 제공하지 않는 새 YouTube API를이다 당신은 당신이 원하는 모든 정보와 태그가 미래에있을 수 있습니다. 나는 json 형식을 사용해야한다. gson 라이브러리를 사용하여 파싱 할 수도 있습니다.

Answer 2

네트워크에서 UI 스레드 예외 이것은 매우 일반적인 실수입니다. UI 스레드에서 net로 작업해서는 안되며, ansytask를 사용하십시오. 여기 HttpUrlConnection working on api level < 11, not working on api level >11 on android
