Starting : Intent  3연속 

액티비티를 죽이려고 별짓을 다했던 주석의 흔적입니다 ..ㅠㅠ

Main -> Story -> Main 으로 오려하면  Rec가 뜨거나 Story가 뜹니다.

MediaPlayer에서 에러뜨는건 초기화안해서 그런거같은데 이게 Intent랑 관련이 있나요

Intent.setFlag로 Top/No History 줘봤는데 백버튼으로 Main은 잘 돌아오는데 

Main에서 아무 버튼이나 클릭하면 Rec나 Story등  한개만 전환이됩니다-_-;  (Rec를 눌러도 Story, Play를 눌러도 Story)

어떻게 해야되나요  부탁드립니다.
