문제
나는 Android Facebook SDK에 대한 상대적으로 새로운 것이며,이를 위해 열매없는 날을 보내고 나의 로그인 활동을 설정하는 데 도움이 필요합니다.나는 문제를 해결할 수 없으며 com.facebook.session을 시도하고 가져올 때마다 ( 자습서 , 자동으로"SessionState "로 변경됩니다. 이는 다시 오류를 해결하는 데 다시 도움이되지 않습니다. 누군가가 이것을 고칠 수 있도록 도와주세요.
Facebook SDK v3.6 및 최신 ADT 및 SDK 도구를 사용하고 있습니다.또한 Facebook SDK는 다른 폴더에 있고 (Android SDK와 함께) 별도의 작업 공간에 프로젝트가 있고 (자습서에서 권장되는 것처럼 FB SDK를 복사하지 않으므로 FB SDK를 복사하지 않았습니다)...에모든 FB 샘플이 잘 작동하고 있으며, Scrumptious의 주요 활동에서 코드를 복사하여 로그인을 작동 시키십시오.
참조 용 코드는 다음과 같습니다.
