我正在使用最新的facebook sdk，我试图按照官方样本创建自己的登录按钮，但是，我在我的应用程序中发现了一个奇怪的行为。
登录后，会弹出一个权限对话框，即使我点击了“接受”，它仍然属于授权例外并且未找到显示权限，如何解决？
谢谢

我的建议是使用单独的Session.StatusCallback实施来登录＆＃39;和＆＃39; requestPostPermission＆＃39;。
private Session.StatusCallback callbackLogin = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
session.removeCallback( this );
if ( session.isOpen() ) {
...
} else if ( session.isClosed() ) {
...
}
}
};
和postPermissions：
private Session.StatusCallback callbackPostPermission = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
session.removeCallback( this );
if ( session.isOpen() ) {
if ( session.getPermissions().contains( "publish_actions" ) {
...
} else {
...
}
...
} else if ( session.isClosed() ) {
...
}
}
};
