Android Question "File name or extension is too long" error

Rubsanpe · Oct 26, 2021

Hi. When I compile the app in B4A I get the message

...
Compiling generated Java code. Error
File name or extension is too long

But it doesn't mention which file it refers to. I have tried to shorten the length of code filenames and layouts, but I can't fix it. Is there any way to find out which file is the cause?

I get the error in the system language (Spanish) and not in the one I have configured in the IDE.

The error message might be misleading here.

Does it happen with all your projects? Where is the project stored?

Rubsanpe · Oct 26, 2021

Hi, I have tried to change the project folder to a shorter one and I have also tried to change the names of B4XPages and layouts.

The current path of the project is "C:\B4X\Proyectos\BO". Until yesterday it was working without problem and it was in "C:\B4X\Basic4Android\Proyectos\BoletinesOficiales".

As it does not work with these changes I understand that the problem must be in the size of the name of some of the files, but I have reduced the size of the last ones that I have modified but it does not let me continue.

I am currently using the recommendations from the B4X installation page and using JDK11.

Hello again. Strangely I have made a cleanup of the project folder and I have removed some libraries that told me in the logs that they were no longer used in the project and now I don't get the error again when compiling.

I will continue testing

Well, one day later the problem reappears. I have tried compiling other projects with no problem. It's an error that comes and goes. Yesterday after cleaning the directory, the problem disappeared, but now it doesn't disappear again.

I have tried disabling the antivirus as indicated in other threads.

I have placed the project in the root of the disk in c:\BoletinesOficiales and there it continues giving the error.

Try to enable the IDE logs and see whether there is anything relevant: https://www.b4x.com/android/forum/posts/50478/

It only happens with this project, right?

Please make a test. Create a new project and add the same libraries. Do you get this error? Can you post a screenshot of the referenced libraries?

MikeSW17 · Oct 28, 2021

The "System.ComponentModel.Win32Exception (0x80004005)" Error seems to have multiple meanings/causes, mostly 'Access Denied' reasons.
File name/length too long description may be a wrong interpretation.

Hi again. Yes the error is indeed only with this project. The complete list of libraries of the project is in the image.

Best regards and thanks

Hi. Sorry I didn't read that part. I have created a new B4XPages project (default content), added the same libraries to it, and the error does not occur.

Well, I have tried to disable the library [B4X][B4XLib] B4XCheckInternetLM, I have compiled and it does not give error. I have included it again in the project and the error returns.

I don't know if the problem is caused by it or if it is caused by using too many libraries in the project. I have tried to add 3 or 4 more libraries not used in the project and the error does not appear.

I have added for example the xGraph library and the error returns... It seems to be some kind of limitation in the reference to certain libraries...

Rubén

Erel · Oct 31, 2021

Try to unzip the library (b4xlib) and add the modules directly to your project. My guess is that it is related to something in the manifest.txt file of that library.

Rubsanpe · Oct 31, 2021

Ok thank you. I will try it. If I see any possible new hints I will let you know. At the moment by removing those libraries the problem has disappeared.

Hi again. I have tried to add the StringFunctions2 class https://www.b4x.com/android/forum/threads/stringfunctions2.98112/ and the error appears again. Have I reached a limit?

Rubén

Erel · Nov 3, 2021

If possible please create a zip with the project and all the additional libraries, and send it to me.

Rubsanpe · Nov 3, 2021

Hi. I have sent the project and the libraries from the account [email protected] to [email protected].

Rubén

Erel · Nov 4, 2021

Thank you. I was able to reproduce it and extend the limit. It should compile properly in the next version.

Just for interest, what limit?
