I try to use this example. But I have some problems:

I/python  ( 4464):  ...
I/python  ( 4464):  >>    1:#:import XCamera kivy_garden.xcamera.XCamera
I/python  ( 4464):        2:#:import is_android kivy_garden.zbarcam.utils.is_android
I/python  ( 4464):        3:<ZBarCam>:
I/python  ( 4464):  ...
I/python  ( 4464):  Unable to import package 'kivy_garden.xcamera.XCamera'
I/python  ( 4464): Python for android ended.

buildozer.spec

requirements = python3,
               kivy,
               kivymd,
               Cython,
               jnius,
               python-for-android,
               Pillow,
               libzbar,
               pyzbar,
               xcamera,
               kivy-garden-xcamera,
               zbarcam

Thanks for help.

I am seeing the same problem with my code:
Simple test app that opens the camera when a menu button is clicked.
App runs fine in Windows and compiles using buildozer.
But when camera open code runs from .apk, my app errors with same error

I have tried various requirement lines in my buildozer.spec including the sample one in zbarcam code root but none work.

No idea if this is a zbarcam issue, xcamera or perhaps buildozer

Has there been a recent build and test to android of the code?

I decided this problem (for Android). Try to do next steps:

1. download: kivy_garden/zbarcam, and put in your project with structure preservation (/home/bill/Inspector/kivy_garden/zbarcam/all_files)
2. And from project dir [name_your_dir]/.buildozer/android/platform/build-arm64-v8a/build/python-installs/[name_your_project]/arm64-v8a delete packages: xcamera, kivy-garden-xcamera, zbarcam. The next build will load them again.
3. I left only in requirements:

requirements = ...,
               ...,
               libzbar,
               pyzbar,
               xcamera
