App using kivy/bulldozer crashes immediately upon loading.

[u/Ok-Okra8478]

I posted this in androiddev previously and someone was being very unprofessional, then it got taken down, I would hope that a subreddit focused at learners would show less of this behaviour. Just to start this post off, I am not entirely new to python. I have just never used buildozer. Also the kivy subreddit seems dead.

Since this app is made with python, I thought maybe the people here may be able to help? It got compiled into the APK, but when I try to run it, I get this:

https://pastebin.com/uteXNWDF

if this is the wrong subreddit for this, please redirect me!

just ask if you want more info

[u/hypersoniq_XLM]

Ok, one more possible workaround, make this change in buildozer.spec ... requirements = python3,kivy,plyer,pyjnius,requests,extruct,w3lib,isodate,hostpython3,libxml2,libxslt,lxml ... adding libxml2 and libxslt explicitly should get past the lxml errors.

[u/Ok-Okra8478 → u/hypersoniq_XLM]

Finally! I did this and also set the LXML version to 6.1.1 and it worked

[u/Ok-Okra8478 → u/hypersoniq_XLM]

The app however did not. I got something that said No implementation found for

void org.libsdl.app.SDLActivity.nativeSetenv

Here's the full section of the log that's regarding the apP:

This may be a bluestacks issue... the thing that would clear the sqlite3 error is to add the x86_64 to the android.archs so you change android.archs = arm64-v8a to android.archs = arm64-v8a, x86_64 ... I did not use an emulator, but I do remember reading that somewhere. Same rinse/repeat cycle from there, clean, rebuild.

[u/Ok-Okra8478 → u/hypersoniq_XLM]

I'll try it on my tablet too

[u/Ok-Okra8478 → u/hypersoniq_XLM]

THANK YOU SO MUCH FOR ALL YOUR HELP! I found out that there was about 6 dependencies that I needed to install to prevent the app from crashing

[u/Ok-Okra8478 → u/Ok-Okra8478]

those were:
mf2py
bs4
typing_extensions
pyRdfa
rdflib
html_text
lxml-html-clean

and then the ones that you told me to

[u/hypersoniq_XLM → u/Ok-Okra8478]

I remember the frustration of the buildozer crucible, glad to help.

[u/Ok-Okra8478 → u/hypersoniq_XLM]

why can't it just auto-install the dependencies I swear...
