이런식으로 작성되어있는 기본 카메라 어플 코드입니다. 

안드로이드 어플 개발공부를 막 시작한 사람이라서 세세히 설명 부탁드립니다 ㅠㅠ

 

테스트 기반은 맥용 이클립스 주노, AVD는 4.0.3 젤리빈으로 하고있습니다.

 

사진은 찍는것까지는 되는데 저장이 안되네요. 절대주소값이 잘못된것인지. 뭔가 코딩주소가 잘못된거같은데

 

뭐가 문제인지를 잘 모르겠네요 ㅠㅠ

 

그리고 색상을 반전시켜서 하고싶은데 어떤 코드가 들어가야 되는지 모르겠네요 찾아봐도 잘 안나오고요ㅠ

 

오토포커스 기능을 켰는데 이게 제대로 작동이되는것인지 아닌지 알수가 없어서 문제입니다.

 

안드로이드폰이 있어야 테스트 가능한건가요?

 

 

두서없이 질문드려 죄송합니다 ㅠㅠ

Answer 1

FileOutputStream fileoutstream

= new FileOutputStream(new File(mFileimageRoute, getRealFileName()+".jpg"));

이렇게 한번 해보세요.

메니패스트에 외부 스토리지 쓰기 퍼미션이 있는지 확인해보시구요.

그리고 색상 반전은 안드로이드와 상관없이 이미지 프로세싱에 대해서 공부해보세요.

카메라 기능은 보통 단말기가 있어야 제대로 테스트 가능합니다.

답변 감사드립니다. 해보았으나 별 차이가 없네요.;;;

File[] files = new File("content://media/internal/images/media").listFiles();

이부분에서 문제가 있는것 아닐지;;
