우선 여기저기 검색해보고 .. 또 제가 개발하다가 테스트 해본 결과를 토대로 질문을 드리겠습니다.
3개월 전에 에뮬레이터를 통해서 tcp 소켓을 통해 pc 서버와 통신을 하던 어플을 만든적이 있습니다.
뭐 대충 완성 시켜놓고 그냥 ~ 졸업을 앞두고 있는지라 한참 영어 공부하다가 테스트폰을 입수해서
테스트폰으로 실험을 하는데..
이게 왠..걸...
전송이 되질 않습니다!!!!!!!!!!!!!!!!ㅡㅜ
에뮬레이터로 다시 해봐도 잘 되는데 왜.. 테스트폰에서는 전송이 되질 않는걸까요 . . .

혹시 에뮬레이터에서 tcp 소켓을 통해서 pc 와 통신하는 통신소스코드와
테스트폰에서 wifi 통신을 할 때 쓰는 통신소스코드에 차이가 있는건가요??
전 tcp 소켓만 열어서 통신만 하면 될 줄 알았는데...
난감하네요 . .;; 지금; ; ;
에뮬레이터로 통신은 잘 되는데
테스트(겔럭시s) 기기로 통신을 하니 먹통 상태 입니다.

무슨 상황일까요 . .
답변 부탁드리겠습니다.

제가 TCP는 아니지만, 브로드 캐스트 방식으로 데이터 주고 받는건 했었는데, 데이터 주고 받는건 둘다 이상 없이 잘 됬습니다.
WIFI 부분은 구글링 하시면 잘 나오는데, 한번 찾아보세요.. 혹시 못찾으시면 저한테 쪽지로 남겨주세요..

차이점 없습니다.

일단 디버그를 하시면서 어느 부분에서 어떤한 문제로 안되는지 보셔야 할듯 합니다.

예외가 발생할수도 있으니까요.
