널리고 널린 상용코드인데 이게 터지네요

디버깅 해보니

catch (Exception e)
{
    e.printStackTrace();
}

가 터지더군요

resultcode는 -1이던데 이게 무슨 의미인가요

추가)스택트레이스 오류문입니다

Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media/35 from pid=661, uid=10058 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()

read_external 저거 문제를 물어보니 매니패스트 추가 관련 문제라고했는데

넣긴 넣었어요 근데 안되더라구요
