Question

我正在使用Jaybird连接到Firebird sql，我的应用程序正常连接。但今天我无法联系。

我做的唯一改变是在android studio中的inspector中执行自动校正器。我不知道是什么导致了这个错误。

正如我昨天发表的评论所暗示的那样，错误意味着您的用户名和/或密码不正确（错误335544472 = 您的用户名和密码未定义。请您的数据库管理员设置Firebird登录。 ）。我不知道这是如何由格式/布局更改引起的。

您的用户名或密码已更改（在您的代码或服务器上），或者您正在连接到与您预期不同的Firebird服务器。

如果您尝试连接到Firebird 3（beta / RC）服务器而不设置对旧版身份验证的支持，也可能发生此错误。另请参阅Jaybird and Firebird 3.0 Beta 2。

您可能还想检查Jaybird for android的安装，因为它似乎缺少错误消息属性文件。

无法从Android连接到Firebird服务器
