android.os.NetworkOnMainThreadException

안녕하세요.

android.os.NetworkOnMainThreadException

메인스레드에서 네트워크 통신을 할려고 하셧군요~

안드로이드에서 이건 절대 허용안한답니다.

간단하게 코드로 보여드리겠습니다.

수정전  - android.os.NetworkOnMainThreadException 오류발생

String rtnVal = Request_Server_Login_Check(url, sel_member_id,sel_member_pw);

수정후

// Thread로 웹서버에 접속
new Thread() {
   public void run() {
      try {
         String rtnVal = Request_Server_Login_Check(url, sel_member_id,sel_member_pw);
         DLog.d("bsj-mgr", rtnVal);
      } catch (IOException e) {
         e.printStackTrace();
         showDialogCommonAlert(R.string.xml_login_you_can_not_start_the_program_Connet_error_http);
      }
   }
}.start();

private String Request_Server_Login_Check(String urlStr,
                                          String sel_member_id, String sel_member_pw) throws IOException {
    StringBuilder output = new StringBuilder();
    System.out.println(urlStr);
    System.out.println(sel_member_id);


    URL url = new URL(urlStr);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setReadTimeout(10000);
    conn.setConnectTimeout(15000);
    conn.setRequestMethod("POST");
    conn.setDoInput(true);
    conn.setDoOutput(true);

    Uri.Builder builder = new Uri.Builder()
            .appendQueryParameter("sel_member_id", sel_member_id)
            .appendQueryParameter("sel_member_pw", sel_member_pw);

    String query = builder.build().getEncodedQuery();

    OutputStream os = conn.getOutputStream();
    BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
    writer.write(query);
    writer.flush();
    writer.close();
    os.close();

    int resCode = conn.getResponseCode();
    if (resCode == HttpURLConnection.HTTP_OK) {
        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line = null;
        while (true) {
            line = reader.readLine();
            if (line == null) {
                break;
            }
            output.append(line + "\n");
        }
        System.out.println("output==>" + output);

        reader.close();
        conn.disconnect();
    }
    return output.toString();
}

끝입니다!
