Error while trying to create an APK using Buildozer for Kivy Image processing application. Below is the Error Log. Unable to create APK file

[sbasu26]

I have tried creating the APK file in both Python 3.8 and Python 3.6.9. I have tried all the Android Arch options mentioned in the buildozer spec file. In spite of that I am repeatedly getting the same below error, due to which I am unable to create the APK file for this Kivy module using Buildozer

Below is the Error Log:

There is an example of this issue here codelv/enaml-native-cli#21 which suggests a permissions issue.

It is possible is it caused by running or installing using sudo.
