Error while exporting APK file from kivy project

79 Views Asked by At

I want to export my kivy app to APK but I get the following error...
I did this once on Debian 12 and now on Ubuntu 20.04 but I got the same error both times.
Python version: 3.8.10
Buildozer version: 1.5.0
I ran this code: biuldozer -v android debug but I got this error:

In the requirement section of your buildozer.spec file, make sure you have all the requirements that your app depends on. It will be easier to help you if you post your buildozer.spec file. Also, it's buildozer -v android debug not "biuldozer -v android debug". You made a spelling error which can also cause errors. Again it's hard to guide you in the right direction without looking at the buildozer.spec file.
