SWIG VS PyJNIus

How is this any different than a mature tool such as SWIG (https://www.swig.org/)?

I've used SWIG extensively with Python to call C code and import C headers for testing/tooling purposes.

For pure C, CGO. For C++ they are likely creating shims with Swig: https://www.swig.org/

I mostly write in C and C++ so for language bindings I use Swig a lot. Say Im creating a machine learning library in C++, its very easy to create a Python API that can call the C++ classes and methods using Swig. iirc, I am using the same swig interface file to create bindings for Python, OCaml, R and even Fortran. Feel free to DM me if you got any more questions or anything!

Swig can make c++ types and functions available to python.

The likes of SWIG is often used to link C library-like code to 11-ish other widely used languages.

Maybe you could use swig to create a wrapper for Java.

But, you might find these links interesting: * https://github.com/swig/swig/issues/918 * https://github.com/kaby76/swigged.llvm

I am not aware of any good example code for this, but you can access platform-specific APIs with pyjnius (android) and pyobjus (ios). This should allow you to implement fingerprint authentication using Google/Apple APIs for those platforms -- for Windows, Linux, MacOS you probably will need to research other solutions for doing this with Python (it doesn't really involve kivy)

In terms of Kivy and Android, there are two main repositories worth checking out. The first is pyjnius which is a bridge to the Android APIs, and the second is plyer which uses pyjnius to implement Android-specific features (see plyer/platforms/android directory)

I have never used KeyStore to be clear, but yes, you would use pyjnius to access native Android classes/services. Just a quick google landed this issue which contains some partial autoclass that probably is something like how you'd do this..
