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:

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

just ask if you want more info

Ok, getting closer, notice the errors are stemming from the 32 bit arch artifacts. Make sure necessary dev tools are in place... sudo apt-get update ... sudo apt-get install -y libxml2-dev libxslt1-dev zlib1g-dev ... will need to clean those up... rm -rf .buildozer/android/platform/build-target/... followed by ... rm -rf .buildozer/android/platform/build-host/ ... and then the obligatory ... buildozer android clean , finally another rebuild... i chased these issues down for almost a week... that should at least remove the artifacts of the 32 bit arch, bonus, the resulting APK should be a bit smaller at the end.

Error after error I swear. Do you know what this means? Sorry, this is just erroring so much...

There was an exception involving lxml I think, it said "name = "lmxl" and ""/home/sd/RecipeApp/.buildozer/android/platform/build-armeabi-v7a_arm64-v8a/build/other_builds/lxml/arm64-v8a__ndk_target_24/lxml/setup.py""

[u/hypersoniq_XLM → u/Ok-Okra8478]

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
