문제 최대한 빨리 페이스 북의 로그인에 대한 버튼을 클릭으로 새로운 활동에가는 경우에 상관없이, 사용자의 현재 상태는 무엇입니까입니다!
누군가 저를 도와 줄 수 있습니까?
'session'이 열리지 않았습니까?'onClickLogin()'메소드에 갈 수 없습니까? –
다음 줄이 작동 할 때 onclicklogin() 메서드가 실행됩니다. Intent intent = new Intent (MainActivity.this, SelectionFragment.class); MainActivity.this.startActivity (intent); – defiant
@oDx 새로운 활동을 시작하기 전에 페이스 북 인증을 받아 보셨습니까? –
