我在使用我的应用登录facebook时遇到问题。 登录仅在未安装Android Facebook应用程序时有效。在这种情况下，你将从Facebook获得一个弹出窗口。 安装Facebook应用程序后，登录将重定向到应用程序。在这种情况下，我没有得到我的会话令牌，而是收到消息：CLOSED_LOGIN_FAILED
我一直在寻找这个地方，但我真的找不到问题。
这是我片段中的代码，登录按钮是通过XML创建的：
private void initButtons()
{
btnFacebook.setApplicationId(v.getContext().getResources().getString(R.string.app_id));
btnFacebook.setReadPermissions(Arrays.asList("email", "public_profile", "user_birthday"));
btnFacebook.setFragment(this);
btnFacebook.setSessionStatusCallback(new StatusCallback()
{
@Override
public void call(Session session, SessionState state, Exception exception)
{
Log.d("Token:",session.getAccessToken());
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this.getActivity(), requestCode, resultCode, data);
}
我可能缺少什么想法？同样，登录只能在没有安装facebook应用程序的情况下运行
编辑： 当使用的帐户已经注册了应用程序时，我收到会话已关闭登录失败的消息。当用户首次使用此应用程序登录（添加到他们的帐户）时，结果应该是
