buildozer kivy build failled: armeabi-v7a gradlew failed

[Jena]

I am trying to build for kivy in ubuntu. The command I used is buildozer android debug. I am using python 3 in windows 10. I am not able to identify the source of the error

I haven't plugged in an android phone. Can this explain the error?

Python: 3.7

OS: Ubuntu 20.04

Kivy: 1.11.1

Command: buildozer android debug

    #    List as sections

    #

    #    You can define all the "list" as [section:key].

    #    Each line will be considered as a option to the list.

    #    Let's take [app] / source.exclude_patterns.

    #    Instead of doing:

    #

    #[app]

    #source.exclude_patterns = license,data/audio/*.wav,data/images/original/*

    #

    #    This can be translated into:

    #

    #[app:source.exclude_patterns]

    #license

    #data/audio/*.wav

    #data/images/original/*

    #

    

    

    #    -----------------------------------------------------------------------------

    #    Profiles

    #

    #    You can extend section / key with a profile

    #    For example, you want to deploy a demo version of your application without

    #    HD content. You could first change the title to add "(demo)" in the name

    #    and extend the excluded directories to remove the HD content.

    #

    #[app@demo]

    #title = My Application (demo)

    #

    #[app:source.exclude_patterns@demo]

    #images/hd/*

    #

    #    Then, invoke the command line with the "demo" profile:

    #

    #buildozer --profile demo android debug

[Moazzam Muhammad]

there is an environment OR another building issue, to resolve in this ENV please provide full buildozer debug log.

OR simply pull buildozer docker image for isolated & clean ENV per build after install docker for linux(or other).
