I'm working on an android app project that will ultimately use OpenCV (didn't reach that part yet). I only finished the functionality part of the project but it keeps crashing as soon as it opens on my Android phone (Haewai P20). Before that, I did the famous "Hello world" test and the app showing these 2 words opened fine. I read a lot of forums but can't find any solutions.
I'm working on PyCharm with python 3.7 and the app works fine when I'm opening it on Windows. Then I'm using buildozer on Ubuntu 18.04 on VirtualBox 6.0.6.
I didn't wanted to copy paste all my logcat, buildozer.spec and log files so you can have a look at them here:
buildozer.spec:
https://drive.google.com/open?id=1DHClpIxnOGKtev2nRefau85v12IzjJWm
log.txt created with buildozer:
https://drive.google.com/open?id=1wlQmQjWH27WRef--tLPtN9FGWTE13lLL
logcat.txt (only the part where I installed it and opened it):
https://drive.google.com/open?id=17ovrucpeKWpJh6MBw7e5ZUbxO3S1DSnS
I'm not sure exactly what to look at. I have a feeling that there's an incompatibility between Python versions (buildozer uses 2.7) but I'm not sure how to deal with that. If it's really the problem.
Please let me know if you have problems opening these files and if you need anything else.
Thank you very much in advance for your help and time.
Either search for "I python" using an editor or buildozer android debug deploy run > grep "I python"
