As you can see from the repository, we currently provide cffi version 1.13.2 for Python 3.8, cffi 1.15.1 for Python 3.9-3.11, and cffi 1.16.0 for Python 3.12.

If you need another combination, you can build it by following the instructions here.

[flatFeather]

could you please tell me which are the versions of cffi, argon2-cffi and argon2-cffi-bindings for python3.11? I have tried with these that I have found in the repository:

"cffi~=1.15.1",
"argon2-cffi~=20.1.0",
"argon2-cffi-bindings~=21.2.0",

But I'm still facing problems:

briefcase build android

[argon2benchmark] Updating app metadata...
Setting main module... done

[argon2benchmark] Building Android APK...

> Configure project :app
Warning: Python version 3.11 may have fewer packages available. If you experience problems, try switching to version 3.8.

I have also tried with Python 3.8:

cffi: 1.14.3 argon2-cffi-bindings: 20.1.0 argon2-cffi: 20.1.0

But I also get the error CCompiler.compile: Chaquopy cannot compile native code

Can someone help me with this? @mhsmith? is there any way to create the android application with the argon2 library?

[mhsmith]

argon2-cffi version 20 does not require the argon2-cffi-bindings package, so you should remove that from your requirements list.

[mhsmith]

If anyone neads a newer version of cffi, please click the thumbs up button in the top comment, and post a comment explaining why you need it.
