Kivy - Buildozer로 Android APK 만들기

가장먼저 buildozer install하기

git clone https://github.com/kivy/buildozer.git
cd buildozer
sudo python2.7 setup.py install

인스톨이 완료되면 초기화를 실행한다.

buildozer init

init를 완료하고 나면 buildozer.spec 파일이 생성되는데  정보를 적절하게 입력해준다.

# (list) List of Java files to add to the android project (can be java or a

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