AsyncTask 관련 질문이요!

Question

검색하고 싶은 버스 번호를 입력 받아서 해당 번호를 갖고 있는 버스를 출력해주는 어플을 만들고 있습니다.

AsyncTask를 이용하고 있고, 파서는 XMLPullParser를 이용하고 있습니다.

 

 

protected InputStream doInBackground(String... param)
    {
        URL url;
        HttpURLConnection conn;
        InputStream data = null;

        try {
            url = new URL("url값" + param[0]);
            Log.i("String URL", url.toString());

            conn = (HttpURLConnection) url.openConnection();

            try {
                conn.connect();
                data = conn.getInputStream();
            } catch (IOException e) {
                e.printStackTrace();
            } 
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return data;
    }

이런 오류가 뜹니다ㅠㅠ

 

url 주소는 시크릿키 값때문에 지웠고ㅠㅠ

로그에 나온 주소 값으로 들어가 봐도 접속이 잘되는데 왜 자꾸 연결이 안되는지 모르겠습니다ㅠㅠ

Answer 1

xml 파싱 시 network 에 연결되어 하고 있는데 그게 main thread 에서 도나 봅니다. 그 파싱 부분도 asynctask 에서 돌리세요 

NetworkOnMainThreadException 에 대해서 검색하시구요
