권한은 android.permission.WRITE_EXTERNAL_STORAGE 준상태입니다 .
그냥 SDCARD 에는 생성이 되는데 폴더를 만들려니 문제가 되네요 .
mkdir로그는 이렇게 나오는데 .

FileOutputStream 이부분에서 FileNotFoundException 이 납니다 .

구요 파일을 못찾는다는 이야기인거 같은데 ..

File makedir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/EYEONE","text.txt");
하면 파일은 이미 생성된게 아닌가요 ?

try {
            mkdir.createNewFile();
        } catch (IOException e) {
            throw new IllegalStateException("Cannot create file: "
                    + makedir.toString());
        }

이런 식으로 생성해주는 명령어가 필요합니다.

하시려는게 /sdcard/EYEONE/text.txt 디렉토리를 만들려는 건가요, 아니면 /sdcard/EYEONE/ 디렉토리에 text.txt 파일을 만들려는 건가요?
후자인 경우
File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() , "

EYEONE") ;
dir.mkdirs() ;
File f = new File(dir , "text.txt") ;
같은 식으로 디렉토리를 먼저 만든 다음 그 안에 파일을 생성해야 합니다.

감사합니다 보고 해결했습니다 .
그냥 new File 하면 생성되는게 아니군요 ㅎㅎ
