Android Wi-Fi Direct 서비스 검색을 사용하고 있습니다. 연결 정보를 사용할 수있는 경우 그룹이 만들어지면 그룹 정보를 요청합니다. 어떤 이유로 클라이언트로 연결할 때 그룹 소유자를 그룹에서 가져올 수 있지만 클라이언트 목록은 비어 있습니다. 그룹 소유자로 연결하면 그룹 소유자와 클라이언트 목록을 가져올 수 있습니다. 채팅 조각에 도달하면 그룹 소유자와 클라이언트가 누구인지 표시하려고합니다. 또 다른 문제는 그룹 소유자의 기기 이름이 비어있는 것처럼 보이지만 나머지 정보는 주소 (주소 행을 삭제함)와 같이 정확하다는 것입니다. 몇 군데에 그룹 정보를 요청했는데 클라이언트로 연결되었을 때 클라이언트 목록을 가져올 수 없었습니다. 내가 SERVICE_CONNECTED 인 텐트를 받으면 채팅 조각으로 전환합니다.클라이언트로 연결할 때 클라이언트 목록이 비어있는 이유는 무엇입니까?
