인터넷에서 문자열 가져 오기와 관련된 문제

Question

그래서 내 앱이 인터넷의 문자열 파일에서 텍스트를 가져와 표시하도록하려고합니다. 하지만 오류가 발생하지 않고 계속 충돌하기 때문에 문제가 어디에서 발생하는지 알 수 없습니다.

여기에 내 현재 코드의 복사본 (오류가 내 IDE로 표시되고 있지)

Answer 1

당신이 UI 스레드에서 인터넷에 연결 시도했기 때문에 NetworkOnMainThreadException를 얻을 수 있어야합니다. 당신은 This Thread 귀하의 문제를 해결하기 위해 볼 수 있습니다, 당신은 AsyncTask 또는 처리기를 사용해야합니다.

당신은 다음 코드에서 해당 오류를 얻을 :

try { 
     OpenNews1(); 
    } catch (ClientProtocolException e) { 
     OpenNews(); 
     e.printStackTrace(); 
    } catch (IOException e) { 
     OpenNews(); 
     e.printStackTrace(); 
    } 

OpenNews1에 당신이 인터넷에 연결하려고.
