블루투스 채팅 안드로이드 연결/발견 버그

Question

블루투스 채팅을 기반으로 안드로이드 블루투스 게임을 개발 중입니다. 잘 작동하는 것처럼 보이지만 매 5 - 10 건마다 응용 프로그램 충돌이 발생합니다. 이는 버퍼가 오버플로 된 것 같습니다. 한 대의 장치를 서버로 사용하고 다른 하나의 장치는 클라이언트로 사용합니다.

때때로

그리고 최악의 일 : 클라이언트 (HTC EVO 4G)이 추적과 충돌 Nexus 7)이 작동을 멈추게하려면 다시 부팅해야합니다. 스택 :

Maybe BluetoothChat app doesnt closes sockets well, when connection is closed? 

어떤 도움이 유용 할 것이다!

Answer 1

마지막으로 연결이 끊어 지거나 실패 할 때마다 onFinish()를 호출하는 등의 나쁜 해결책으로 끝났습니다. 내 사건에는 적절하지만 다른 사건에는 적절하지 않습니다. 그것은 저에게, BluetoothChat에있는 connectionLost() 함수가 불완전한 것 같습니다. 다른 방법으로 포트를 정리해야합니다.
