#
#[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

#    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

What am I missing?

[ckaldemeyer]

Hi @RobertFlatt and thanks for your answer. The "Confirmation question" comes from the invokation of buildozer android debug.
Can you provide an example on how to invoke this command correctly (with a confirmation via "Yes") or provide a full example the contains the installation of all requirements?

[ckaldemeyer]

I have now used the docker image: https://github.com/kivy/buildozer#buildozer-docker-image
Thanks anyway!

See my answer here: https://stackoverflow.com/questions/71632474/automatically-build-android-apk-packages-using-kivy-and-buildozer-in-gitlab-ci/

[bambier]

I solve it by this way

[DivyanshBind]

Who can I solve this problem in windows as "sudo apt-get" command. I didn't known how to paste these commands where???

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install libstdc++6
sudo apt-get install aidl

[dhananjayladole]

Where do we use this?

You have to use these in Linux otherwise you have to install WSL

[RobertFlatt]

Aidl is installed automatically (it is part of the Google tools) when Buildozer first runs.

This automatic install will fail if you don't accept the Google licence agreement. See link in a post above from me about what to do if you did not accept the license agreement.

Buildozer runs on Linux, as a previous answer says if you use Windows you must install WSL and run Buildozer from there.
