Android의 모바일 카메라 앱에서 사진을 찍은 후 onActivityResult의 Null 포인터 예외

이것은 Unity와 Native Android를 연결하는 데 사용하는 UnityBridge의 코드입니다.

Unity와 Android 사이의 다리는 성공적입니다. Unity에서 openCamera 메서드를 호출하면 카메라 앱이 열리고 사진을 찍을 수 있습니다. 촬영 후 이미지는 내부 메모리의 Demo 폴더에 저장됩니다. 이 단계까지는 문제가 없지만 사진을 저장 한 후 앱 강제가 종료됩니다. 다음과 같이 cmd에서 로그를 얻었습니다. onActivityResult에서 얻은 Intent 데이터가 null이라고 생각합니다. 누군가이 오류를 해결하도록 도와주세요. 이미지를 저장소 카드의 데모 폴더에 저장하고 촬영 한 사진의 파일 이름을 포함한 전체 파일 경로를 문자열 변수로 가져와 다음 프로세스를 위해 전체 파일 경로를 다시 단일화 할 수 있도록해야합니다. 가능합니까?
