Facebook sdk 3.0 및 Android로 게시

Question

나는 여기에서 많은 자습서와 답변을 읽었지만 클릭 한 버튼을 구현할 수는 없으며 벽에서 일부 텍스트를 게시 할 수 있습니다 (프로그래밍 방식으로 로그인하면 됨). 나는 조각과 두 개의 버튼으로했지만,이 코드는

어디에 문제가있어? 내가 미친거야! 매우 감사합니다!

귀하의 문제는 귀하의 onResume 메소드에서 onSessionStateChange를 명시 적으로 호출하고있는 것입니다. 콜백은 어쨌든 (귀하의 승인 요청이 돌아 왔을 때 onActivityResult를 통해) 호출했을 것입니다. 이로 인해 2 개의 권한 요청이 동시에 게시되므로이 오류가 표시됩니다. onResume()에서 onSessionStateChange 메소드를 제거해보십시오.
