I have converted a .py file into an apk file where the camera of the mobile device is used, for that I am using the kivy library, and compiling all this with buildozer in the pycharm editor
To compile the application, use the command:
buildozer -v android debug
the problem is that once installed on my mobile device, when opening the application it closes automatically, so to see the error use the log cat command
adb -s 1573273300008C8 logcat *:S python:D
and the error generated is the following:
(venv) acardenas@acardenas-VirtualBox:~/PycharmProjects/ArucoProject/bin$ adb -s 1573273300008C8 logcat *:S python:D

It refers to the fact that I am missing the config.py file
Look for the config.py file and it has the following code, but I don't understand why it generates the previous error, I need help with that please.

I found the problem, in the buildozer request, I was putting opencv-python and it should be just opencv
