无法从Android连接到Firebird服务器

Question

I'm using Jaybird to connect to Firebird sql, my app was connected normally. But today I can't connect.

The only change I made was to execute the auto corrector in inspector, in android studio. I have no idea what is causing this error.

As implied by my comment from yesterday, the error means that your username and/or password is incorrect (error 335544472 = Your user name and password are not defined. Ask your database administrator to set up a Firebird login. ). I don't see how this could be caused by a format/layout change.

Either your username or password has been changed (in your code or on the server), or you are connecting to a different Firebird server than you expect.

This error could also happen if you attempt to connect to a Firebird 3 (beta/RC) server without setting up support for legacy authentication. See also Jaybird and Firebird 3.0 Beta 2 .

You might also want to check the install for Jaybird for android, as it seems to be missing the error message properties file.
