안녕하세요

지금 Socket통신을 사용해서 개발중인데 USB연결했을 때

에뮬레이터에서는 앱이 돌아가는데 폰에서는 안돌아갑니다.

ㅠㅠㅠㅠ

서버랑 클라이언트와 같은 ip(wifi로)를 핸드폰에서도 사용하면 폰에서도 돌아가는데요 

 핸드폰이 4g일때 역시 안돌아가구요,ㅠㅠㅠㅠ...

핸드폰이 다른 ip일 때 되게 하려면 고정IP로 받아서 하면 된다해서 했는데 안되네요 ㅠㅠ

log는 이렇게 나옵니다ㅠ_ㅠ

java.net.ConnectException: failed to connect to /203.153.146.251 (port 7000): connect failed: ETIMEDOUT (Connection timed out)

도와주세요ㅠㅠㅠㅠ
