이 코드에서는 제 HTTP 관련 코드가 올바르게 작동하며 토스트 메시지에서 올바른 결과를 제공합니다. 그러나 HTTP 콘텐츠 (XML)의 구문 분석을 적용하면 강제로 닫힙니다.HTTP를 통해 XML을 구문 분석하는 동안 오류가 발생했습니다.

내가 여기서하고있는 것과 정확히 무슨 문제가 있습니까?

어딘가에 자세한 정보가있는 메시지가 있어야합니다. catch 블록의 인쇄물에 아무 것도 인쇄되지 않습니까? –

또한 네트워크 I/O 및 분석을 주 응용 프로그램 스레드에서 수행하지 마십시오. AsyncTask 또는 다른 형태의 백그라운드 스레드를 사용하십시오.

이제 내 코드가 작동 중입니다 ... 늦게 답장을 드려 죄송합니다 ... 나는 HTTP를 사용하고 응답을하고있었습니다 .. 내 PHP는 적절한 XML을 생성하지 못했습니다 그것은 오류를주고있는 그게 .. 다른 방법도 내가 http를 사용하는 대신있어 n은 우리가 직접 sax 파서를 사용하여 php url의 매개 변수를 전달할 수있는 응답을 데리고 .. 그게 나를 위해 매우 쉽게된다 .. – Sam
