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
