Python-for-android: No "pil" or "pillow" avaliable for Python 3

[etc0de]

I renamed this issue and contents a couple of times because I'm silly and confused about PIL & pillow. Anyway, the state is that none of them are available with python3crystax since PIL is hard-wired to python 2 and --requirements=pillow doesn't work, since without a recipe it packages the wrong .so library (incorrect architecture). That means, effectively, no PIL/pillow for any python 3 app which is unfortunate :cry:

old issue text:

The "pil" recipe is misguidedly hardwired to python 2:

 depends = ['python2', 'png', 'jpeg']

This breaks the build with Python 3:

# p4a apk --debug --private /my-app/ --orientation user --window --package=org.example.myapp --name "My application" --version 0.1 --bootstrap=sdl2 --requirements=python3crystax,pil,sdl2,pysdl2,pyjnius --arch=armeabi-v7a

[INFO]:    No dist exists that meets your requirements, so one will be built.
[ERROR]:   Didn't find any valid dependency graphs.
[ERROR]:   This means that some of your requirements pull in conflicting dependencies.
[ERROR]:   Exiting.

I suggest this should be fixed.

Based on a conversation in IRC chat, it seems like this is actually a fault in the pil recipe being hardcoded for Python 2 instead of working with both. I updated the ticket description accordingly.

From what I recall PIL is deprecated upstream and not compatible with Python3 (also see https://github.com/kivy/python-for-android/commit/c60e02d2e32e31a3a754838c51e9242cbadcd9e8). Pillow is the one that should be used https://github.com/kivy/python-for-android/pull/786 but it's in work in progress.

Yeah I use pillow in my desktop build. Without it, there's no way I can ever port this application to Android. :cry:

[AndreMiras]

Yep I also need it for one of my apps, but don't have time recently to help with the pull request. If you feel like it please take a look. In the meantime, do you think we can close this issue since PIL is not Python3 compatible upstream anyway?

[etc0de]

Well the problem really is that with Python 3, you have no (PIL)low of any kind. I don't see how that is resolved. I renamed it confused by the situation about the old PIL and python 3 support, but that's because I'm a silly person, not because it would no longer be an issue

[etc0de]

I changed it back now, sorry for the confusion :fearful: I won't touch the issue description anymore now, I promise

[AndreMiras]

I understand, it's not resolved, my point it's it's already being addressed in https://github.com/kivy/python-for-android/pull/786 so somehow duplicated even though far from being resolved.
Edit: but I'm fine leaving it open :smile:

[etc0de]

Well I suggest it would be a good point to close this once the pull request is actually merged! (I think that's how it is commonly done in other projects: having both a ticket & associated pull request) However, if you think it should be closed now, I can close it if you want. It's not like I wanna manage your project for you or something
