Python 3.9 failing to load kivy

[syleishere]

Obfusk's patches for python-for-android: https://github.com/kivy/python-for-android/pull/2337/files/f55af300a95eccec877a21ab12456bec906988a5

OK I got around to testing obfusk's patch, something still needs patching: TEST SETUP AS FOLLOWS:

Python 3.8 buildozer test with obfusk's patches: buildozer.spec: (relevant lines for testing helloworld from kivy site) requirements = python3==3.8.6,hostpython3==3.8.6,kivy==2.0.0rc4,https://github.com/kivymd/KivyMD/archive/master.zip,pygments,sdl2_ttf==2.0.15 #obfusk's patches p4a.source_dir = %(source.dir)s/../python-for-android RESULTS from logcat on Pixel 4 XL: (PASS) http://sunsaturn.com/kivy/3.8.txt

Python 3.9 buildozer test with obfusk's patches: buildozer.spec: (relevant lines for testing helloworld from kivy site) requirements = python3==3.9.0,hostpython3==3.9.0,kivy==2.0.0rc4,https://github.com/kivymd/KivyMD/archive/master.zip,pygments,sdl2_ttf==2.0.15 #obfusk's patches p4a.source_dir = %(source.dir)s/../python-for-android RESULTS from logcat on Pixel 4 XL: (FAIL) http://sunsaturn.com/kivy/3.9.txt

Additional comments: only thing that affects it failing is (python3==3.9.0,hostpython3==3.9.0) after running numerous tests with different modules like kivymd or just setting python3==3.9.0,hostpython3==3.9.0,kivy==2.0.0rc4 only in requirements line. As you can see from logs, kivy is not getting loaded for some reason

[obfusk]

This is a bug in kivy.

[syleishere]

Nice job finding that kivy bug obfusk. If we can get these commits in kivy master and on python-for-android, whole world can start using python 3.9 on android 👍

[obfusk]

A fix has been merged (in kivy master).

is it fixed by now?? as I checked Python 3.9 don't have Python 2 supports. so it should be quite lighter than the older 3.* versions and its should be helpful for building smaller apk i guess

[obfusk]

AFAIK it's fixed, but you need to use kivy==master,python3==3.9.1,hostpython3==3.9.1 (for now).

[RaSan147]

getting too many errors. Re-running and will send the error messages here

AFAIK it's fixed, but you need to use kivy==master,python3==3.9.1,hostpython3==3.9.1 (for now).

here are the logs. using ubuntu (actually lubuntu due to storage shortage) 20.04 and builtin python3.8.1

.spec file: buildoze.spec pastebin terminal log: terminal log pastebin

You also need p4a.branch = develop. And the second paste you linked gives me a 403 error.

develop branch breaks other things however: my typical build specs: requirements = python3==3.9.0,hostpython3==3.9.0,kivy==2.0.0,https://github.com/kivymd/KivyMD/archive/master.zip,aiomysql,pymysql,setuptools==51.0.0,pygments,sdl2_ttf== 2.0.15 OR: requirements = python3==3.8.6,hostpython3==3.8.6,kivy==2.0.0,https://github.com/kivymd/KivyMD/archive/master.zip,aiomysql,pymysql,setuptools==51.0.0,pygments,sdl2_ttf== 2.0.15

will break under p4a.branch=develop

[syleishere]

Hold up on that, it's for some reason breaking on master branch as well all of a sudden.

[syleishere]

Ok I looked into that error seems was just someone updated pymysql and that broke aiomysql was able to fix under python 3.8.6 with: requirements = python3==3.8.6,hostpython3==3.8.6,kivy==2.0.0,https://github.com/kivymd/KivyMD/archive/master.zip,aiomysql==0.0.21,pymysql==0.9.3,setuptools==51.0.0,pygments,sdl2_ttf==2.0.15

p4a.branch = develop

[syleishere]

SO I ran a simple hello world example test with: p4a.branch = develop requirements = python3==3.9.0,hostpython3==3.9.0,kivy==2.0.0rc4 also: requirements = python3==3.9.1,hostpython3==3.9.1,kivy==2.0.0 also: requirements = python3==3.9.0,hostpython3==3.9.0,kivy==2.0.0

All of them all of a sudden DO NOT load kivy. So kivy codebase is broken once again....

It should be noted simply replacing with 3.8.6 works in all examples including post before this one, so something is broken in kivy core again.

This was working in December, not sure what happened.

[obfusk]

Unfortunately, the fix in kivy didn't make it into 2.0.0. ATM you need to use master.
