이렇게 firebase에서 사진을 내려받는데요 결과적으로 핸드폰 내에 Picture 폴더에 저장되고 Log 찍어보면
 
file:///storage/emulated/0/Pictures/TackAlbum/20180727_220403qweasdqwesadfdsa.jpg
 
이런식으로 Picture 밑에 TackAlbum 안에 이미지가 들어가있고 실제로도 그렇고요 그런데 문제는
갤러리를 들어가보면 사진이 저장된 폴더가 Picture에요 위에 경로 처럼 TackAlbum 이 아니라 Picture 로 나와요 왜 이러는지 모르겠어요 분명 Picture 안에 TackAlbum만들고 그 안에 이미지 넣고 실제로도 그런데 갤러리에서만 Picture에 있는게 이해가 안되네요;; 해답 부탁드립니다 !!
