java.lang.IllegalStateException: commit already called

FragmentManager를 만들어 모든 Fragment를 만져주는 기능을 만들려했다
replace를 해준 뒤 commit을 하는 로직인데 에러가 발생했다

FATAL EXCEPTION: main

    java.lang.IllegalStateException: commit already called

fragmentTransaction.replace(container, fragment).commit();

FragmentTransaction 객체를 새로 생성해주어 해결

FragmentTransaction fragmentTransaction = ((MainActivity)mContext).getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(container, fragment).commit();
