문제가 있습니다. 다음 프로그램을 실행할 때 NoClassDefaunderError가 발견되었지만이 클래스가이 프로그램에 존재합니다. 나는 DVM에 의해 통해 왜이 오류를 이해하지 않았다클래스가 프로그램에 존재하는 동안 NoClassDefoundError
이프로그램은 다음과 같습니다

그리고 오류는 다음과 같습니다 사전에

고맙습니다 ...
모든 jar 파일에서'FBSessionDelegateImpl'에 액세스하고 있습니까? 이전 버전의 jar를 사용 중일 수 있습니다. 그냥 추측 해. 이것은 문제 일 수 있습니다. 클래스 경로도 확인하십시오 –
