You forgot to mention that when building, half of the users will inevitably encounter an error:

Python-for-Android seems incompatible with Gradle 7. Could you try downgrading by setting

distributionUrl=https\://services.gradle.org/distributions/gradle-6.4.1-all.zip

in

pythonforandroid/bootstraps/common/build/gradle/wrapper/gradle-wrapper.properties

[HeaTTheatR]

@Fox520 This is the default and has not been changed by me.

@HeaTTheatR I can't seem to replicate the issue on a fresh install of Ubuntu 18.04
Can you try enabling androidx by adding android.enable_androidx = True in the buildozer.spec

Setting this to false will pass --ignore-setup-py, true will pass --use-setup-py

NOTE: this is general setuptools integration, having pyproject.toml is enough, no need to generate

setup.py if you're using Poetry, but you need to add "toml" to source.include_exts.

#p4a.setup_py = false

(str) extra command line arguments to pass when invoking pythonforandroid.toolchain

Another platform dependency: ios-deploy

Uncomment to use a custom checkout

This option should be defined along with app_url and full_size_image_url options.

#ios.manifest.display_image_url =

(str) Path to build artifact storage, absolute or relative to spec file

build_dir = ./.buildozer

(str) Path to build output (i.e. .apk, .aab, .ipa) storage

bin_dir = ./bin

-----------------------------------------------------------------------------

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

you should use the latest API version , and minimum api to 23 , then enabling android.enable_androidx thanks

[jhay06]

any updates ? please tell if my solution works for you :) thanks

[jhay06]

please add me on the kivymd builder project so i can help to figure out other challenges you had experience

[ProtDos]

I also was able to fix this error partially with the steps from here.
