안녕하세요 다름이 아니라 라즈베리파이에서 서버를 만들어 열어놓고 그 서버에 문자를 보내는 앱을 만들어보고 있는데요
앱 구현해서 전송했다고 뜨긴하는데 서버(구글로 열고)들어가서 콘솔로그 창을 살펴보면 아무 기록도 없더군요
아래는 제가 책보면서 만들어본 문자보내기 앱입니다.

디바이스 실행해서 들어가지긴하는데 무슨 문제인지 잘 모르겠네요 소켓통신이란것도 처음해봐서 난감합니다.
아래는 안드로이드 로그 창인데요

서버 접속버튼 누르고 센드 보내고 close라는 버튼 누르면 로그가 저렇게 뜹니다..
그런데 서버쪽에서 데이터를 받을 수 있도록 뭔가 설정을 해줘야하지 않을까요?
