Cython with Kivy for Android and iOS

[Antonio Peña]

Hello Community,

I've been looking around the Internet but couldn't find any tutorial or examples about the topic. Can you use Cython code in your Kivy application? Since Kivy itself uses Cython, I imagine you can. But how? Should I compile de .pyx file on the Linux's Virtual Machine or on Windows? The first one builds a .so file and the other a .pyd one. Is there any incompatibility when compiling then to an .apk with buildozer or to iOS with its process?

Thanks!

If the target is Android create a local recipe with base class CythonRecipe and all the compile stuff is handled.

In principle very similar code would work for kivy-ios, in practice .....?

Recipe help is non existent so you need to be self supporting.

Some of these are examples of using CythonRecipe
