Question

현재 Android 플랫폼 용 RSS 피드 읽기 응용 프로그램을 만들고 있습니다. 일부 RSS 피드에서 작동합니다. 그러나 다른 사람들에게는 그렇지 않습니다. 특히, '하늘'호스팅 RSS 피드에는 작동하지 않습니다. 하지만 왜 하늘 웹 사이트에서 RSS 피드를 사용할 때마다 위의 오류 메시지가 표시되는지 확실하지 않습니다.

http://www.skysports.com/rss/0,20514,11661,00.xml

나는 내가 사용하고 내 XML 구문 분석과 함께 할 수있는 뭔가인지 아닌지 확실하지 않다 :

RSS 예를 들어 다음과 같이 피드?

누군가 내가 잘못 가고있는 부분을 올바른 방향으로 가르쳐 주시겠습니까?

감사합니다.

은 오류가 발생하는 경우 스택 추적을 인쇄하고 null을 반환하고 예외를 다시 throw하지 않기 때문에 null을 반환합니다. 일반적으로이 오류를 처리하지 않는 것은 좋지 않습니다. 왜냐하면이 경우에도 예기치 않은 동작이있는 것처럼 보이기 때문에 다른 곳에서는 설명하기가 훨씬 어려울 수 있기 때문입니다.
