I have the project on c:\b4android\projects\glose4 that i created a month ago.
I have an old version of the same project on c:\b4android\projects\glose2 that compile without error (when i create a new version, i copy the old project to a new folder)
I think that the problem was with a new layout file that i created yesterday on the new project (glose4).
I delete this file, and I recreate the same layout file on the designer.
After this, the project compile without error.
After restart the computer, i have the same error when i compile the project ."The filename or extension is too long"
Thank you Erel for your help
