ActivityThread에서 Android 애플리케이션 RuntimeException이 소스를 찾지 못했습니다?

Question

네이티브 Android 애플리케이션으로 인해 RuntimeException 문제가 해결 될 수 있도록 도움이 필요합니다. 이 예외의 원인을 정의 할 수 없습니다. 다음은 스택 추적 및 코드입니다. 여기에 무슨 문제가있는 것 같습니까?

예외 스택 추적 + 메시지는 일반적으로 로그 캣에 그대로 조금 더 인쇄됩니다. 스택 추적의 첫 번째 행은 시스템이 Instrumentation.newActivity (ClassLoader, String, Intent)를 호출 할 때 activity 객체를 인스턴스화 할 수 없음을 나타냅니다. 로그 캣, 당신은 같은 것을 찾을 수 있어야합니다. : < 메시지 > 당신이 꽤 관심이 뭔가 "활동 < 구성 요소 >를 인스턴스화 할 수 없습니다 < 메시지 >를"
