아주 간단한 코드로 비디오를 재생하려고하는데, 내가 무엇을 바꿔도 항상 같은 문제가 발생합니다. onCreate의 마지막 줄 onResume이 호출되었지만 surfaceCreated를 호출하기 전에는 아무 것도 호출되지 않고 Activity가 잡히지 않은 예외로 종료됩니다. 내가 뭘 잘못하고 있니?SurfaceView가 생성되기 전에 잡히지 않은 예외 - Android - 비디오 재생

로그 캣 말한다!
당신이 logcat의 정확한 부분을 게시했다고 생각하지 않습니다 ... 예외는 없습니다 ... –
거기에 잡힐 수없는 예외가 있습니다 !! 나는 그것이 어디에서 일어나는 지 모르기 때문에 그것을 어디에서 붙잡을 지 모른다! onCreate() 확인 완료 (on System.out 참조), onResume() 완료, 그리고 응용 프로그램이 catch되지 않은 예외로 끝나고, 그것은 surfaceCreated() 또는 onDestroy() 또는 아무것도 입력하지 않는, 그냥 충돌합니다. 잡히지 않는 예외 (05-06 16 : 39 : 51.326) !! Help :( – Azurlake
