我能够使用我在 android 上的应用程序连接到 Facebook，并查看我的姓名、姓氏等字段。然后我去Facebook.com我的电脑上，从允许的应用程序中删除我的应用程序，然后重新启用（用于测试）。
然后，当我运行我的应用程序时，我在 Logcat 中收到以下错误：
FacebookError: Error validating access token: Session does not match current stored session.
这可能是因为用户在创建会话后更改了密码，或者 Facebook 出于安全原因更改了会话。
我尝试了一切，搜索了论坛 - 但没有运气。
我的代码：
public static final String TAG = "FACEBOOK";
private Facebook mFacebook;
public static final String APP_ID = "00112233211545";// I changed this when i publish to Stackoverflow

}

Log.d(TAG, "sessionValid");

mFacebook.authorize(this, PERMS, new LoginDialogListener());
}
}
