활동이 충돌 함 (파일 처리 및 카메라)

다음 활동은 사진을 찍어 저장 공간에 저장하고 활동의 ImageView에 표시합니다. 사진을 클릭하고 OK 버튼을 누르면 '불행히도 카메라가 멈췄다'라는 메시지가 나타나고 카메라 작동 화면이 표시됩니다. ImageView가 설정되지 않았습니다.활동이 충돌 함 (파일 처리 및 카메라)

logcat에서 스택 트레이스를 보여주십시오. –

로그 캣에서 귀하의 정보가 the Java stack trace associated with your crash 표시되지 않습니다, 그래서 당신 또는 우리에게 도움이되지 않습니다.

다른 문제는 다음과 같습니다 당신은 "file:" + image.getAbsolutePath()에 mCurrentPhotoPath를 설정하고, 그 값은 파일 시스템 경로도 아니고 Uri도 아니다

.
photoFile이 null 인 경우 사진을 찍지 않을 경우 setPic()으로 전화하십시오.
startActivityForResult()은 비동기이므로 사용자가 사진을 찍기 전에 setPic()으로 전화를 걸고 있습니다. setPic() 전화를 onActivityResult()으로 이동 한 다음 RESULT_OK (사용자가 사진을 찍었 으면 좋음을 나타냄)을 얻은 경우에만 이동하십시오.
