이미지를 서버에 업로드하려고하는데, 어쨌든 코드가 FileInputStream 행에서 중지되었습니다. 확실하지 왜 그리고 어떻게 디버깅하거나 그것을 확인하지 않습니다. 여기 내 소스 코드 :서버로 이미지 업로드하기 : FileInputStream에서 멈춤

문제가있는 곳을 확인할 방법이 있습니까? logcat은 중단 점 2에서 중단되었습니다. 중단 점 2 대상 : /storage/emulated/0/20171215-051851.jpg 그래서 탐색기를 확인하면 파일이 있습니다.
예외가 있습니까? –
자세한 내용은 다음을 참조하십시오. java.io.FileNotFoundException : /storage/emulated/0/20171215-051851.jpg : open failed : EACCES (Permission denied)하지만 manifest에서 파일을 읽을 수 있습니다.
대상 SDK 버전? –
