처리 중 버전 3에서 qr 코드 스캐닝을위한 코드를 실행하려고합니다. 이미 QR 코드 라이브러리에서 제공된 예제 코드를 사용하고 있습니다. JDK 8과 android SDK도 설치했는데, 여전히 안드로이드 폰에서 응용 프로그램을 실행할 수 없습니다. 그것은 설치되고 있지만 실행 중 자체를 닫습니다 ("불행히도, QR 코드 예제가 멈췄다"를 보여줍니다) (나는 몇 가지 다른 예제를 시도해 보았습니다!).QR 코드 스캐너 안드로이드 폰에서 실행되지 않는 QR 코드 라이브러리의 예제 코드
여기에 참조 코드와 콘솔에 표시된 오류에 대해서만 코드를 추가합니다 (예제 코드이므로 수정해야하며 변경하지 않았습니다). 프로그래밍에 익숙하지 않으므로 오류가 정확히 무엇인지 알 수는 없습니다. 누군가 좀 봐주세요. 나를 도와주세요.
미리 감사드립니다.
/*
QRcode reader
Generate images from a QRcode generator such as
http://qrcode.kaywa.com/ and put them in this sketch's
data folder.
Press spacebar to read from the camera, generate an image,
and scan for barcodes. Press f to read from a file and scan.
Press s for camera settings.
