Try one of this:

• add this to your build command: --source-packages libmagic
• or in your pyproject.toml file, under [tool.flet] or [tool.flet.android], add source_packages = ["libmagic"]

I'm using a flet==0.25.2, because the music-tag library, which I was helped with in this discussion #4682 , does not work on newer versions. There are no --source-packages here. Also, all requires wrote in "requirements.txt".

[Vlad23052003]

I tried using the pyproject.toml file and it worked in emulator, but the error remained on the phone. Also, there is such a error on emulator:

FileSystemException: Deletion failed, path = '/data/user/0/com.flet.musicid3/files/flet/app' (OS Error: Directory not empty, errno = 39)

[ndonkoHenri]

Try upgrading (in a new virtual env) and follow this new approach with source_packages I shared.

Also, all requires wrote in "requirements.txt".

What do you mean?

What do you mean?

Instead of the pyproject.toml file, I had requirements.txt.

When I try to compile with version flet==0.27.6, I get this error:

With flet==0.25.2 there no such problem. But there is this:

I tried using the pyproject.toml file and it worked in emulator, but the error remained on the phone. Also, there is such a error on emulator:

FileSystemException: Deletion failed, path = '/data/user/0/com.flet.musicid3/files/flet/app' (OS Error: Directory not empty, errno = 39)
