안드로이드 : ClassNotFoundException

Question

나는이 wierd 오류가 나타납니다. 어제 밤에 일하러 돌아 왔을 때, 나는이 오류에 직면했다. 내가 이해하지 못했던 것은 내가 코드에서 아무것도 변경하지 않았다는 것입니다. 그것은 그것이 파랗게 나온 것처럼 느껴집니다.

참고 : 저도 같은 문제에 다른 질문을 검색했고, 나는 몇 가지를 발견했다. 그러나, 나는 그 게시물에 대한 모든 조언을 따랐고 그것은 나에게 도움이되지 못했습니다. 밤새도록 낭비하다가 여기에 올리는 것이 좋은 생각이라고 생각했습니다.

내 코드의 어느 부분이 있는지 함께 알 수 없으므로 적극적으로 살펴보고 필요한 경우 편집 할 것입니다.

지금 당장 같은 문제가 발생했습니다. 장치에서 응용 프로그램을 제거하고 프로젝트를 다시 작성한 다음 다시 설치했습니다. 이번에는 문제에 직면하지 않았고 정상적으로 작동했습니다.

스튜디오에서 즉석 실행 기능을 사용하는 일부 간헐적 인 버그 일 수 있습니다.
