Python3 APK fails to build!

[mrhdias]

I'm trying to build a python3 (python3crystax) apk using kivy and buildozer, but fail build.

[INFO]:    Bootstrap requires recipes ['sdl2', ('python2', 'python3crystax')]

what did you put in your requirements line in buildozer.spec?

[mrhdias]

I find the problem, but it continues to fail.
I try with python3crystax and kivy only

requirements = python3crystax, kivy==master

[ERROR]:   The python3crystax recipe can only be built when using the CrystaX NDK. Exiting.

This is the problem, you must download the CrystaX NDK and tell buildozer to use it.
