Why an error occurs 'python-for-android cannot continue; aborting'?

[HeaTTheatR]

Installed python-for-android using the instructions:

pip install git+https://github.com/kivy/python-for-android.git

I am trying to build a project - https://github.com/inclement/Pyonic-interpreter

Here is the code from Pyonic-interprete/sertup.py (pointed only his way to crystax-ndk):

from setuptools import setup, find_packages
from distutils.extension import Extension
from Cython.Distutils import build_ext

from os.path import join, dirname

packages = find_packages()

with open(join(dirname(__file__), 'version.txt'), 'r') as fileh:
    version = fileh.read().strip()

options = {'apk': {'window': None,
                   'requirements': 'sdl2,kivy,python2,pygments,jedi',
                   'android-api': 19,

)

Run build:

python setup.py apk

What is the problem?

Using Python 2.7

[inclement]

I'm not sure what's wrong here, but it looks like p4a is maybe getting confused between the crystax NDK and the one in ~/.buildozer. Perhaps this is due to a bug somewhere. Does it work if you either delete the ~/.buildozer version, or the crystax ndk (since you're using python2 you don't need the crystax ndk)?

[HeaTTheatR]

Remove folder ~/.buildozer.

[RobertFlatt]

Same problem here, I'm using Python 3.5, Crystax, Gradle (no buildozer)
[WARNING]: include directory doesn't exist: /blah/blah/crystax-ndk-10.3.2/sysroot/usr/include/arm-linux-androideabi

The 'sysroot' include path is explicitly added in pythonforandroid/build.py line 365
And tested for existence in the following line.
The specified path is not part of the Crystax distribution

Workaround : Comment out the test - p4a builds and the apk installs and runs.
To comment the code: make a local clone with git, edit build.py, install the modified clone with pip

[inclement]

Thanks for this note, I hadn't looked at the code to understand the problem, but what you've pointed out makes it clear that the build was broken by a recent merge.

I've reverted that change, does the p4a master branch work for you now?

Sorry about that.

[RobertFlatt]

Confirmed, I get running apk with the new master. Thanks for the fast response. And it is amazingly cool to see Kivy running on my phone :)

I installed python-for-android using (and I assume the git form would also work):
pip install https://github.com/kivy/python-for-android/tarball/master

FYI I use Cython 0.24.1 , and Kivy 1.10.1dev. No idea if these particular versions are required now.

[inclement]

Great, sorry again about breaking things, that's my mistake. I'll try to improve the tests to make sure such a thing can't slip through again.

As far as versions go, using Kivy master with any recent cython version should be fine, I think. Kivy master should become Kivy 1.10.1 stable soon.
