사진 촬영 중 FileUriExposedException

Question

도움이 필요합니다. 나는 외부 microSD가 없기 때문에 사진을 찍고 스마트 폰의 내부 메모리에 저장하는 간단한 응용 프로그램을 작성 중입니다. 앱을 실행하고 사진 찍기 버튼을 누르면 크래시가 발생합니다. 어떻게 처리 할 수 ​​있습니까? 미리 감사드립니다. 여기 모니터 결과입니다

Answer 1

시도 : Activity.onCreate()에서

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder(); 
StrictMode.setVmPolicy(builder.build()); 

. 따라서 VM은 파일 URI 노출을 무시합니다.

두 번째 방법은 문제를 해결하는 대신 Fileprovider을 만드는 것입니다. 여기

는 Good Read

모범 사례가 설정하는 것입니다 FileProvider (당신이 링크를 볼 수 있습니다.)

StrictMode은 문제를 바로 가기 방식으로 해결하는 것보다 더 비슷합니다.
