Buildozer Save

Generic Python packager for Android and iOS

Project README


Buildozer is a development tool for turning Python applications into binary packages ready for installation on any of a number of platforms, including mobile devices.

The app developer provides a single "buildozer.spec" file, which describes the application's requirements and settings, such as title and icons. Buildozer can then create installable packages for Android, iOS, Windows, macOS and/or Linux.

Buildozer is managed by the Kivy Team. It relies on its sibling projects: python-for-android and Kivy for iOS. It has features to make building apps using the Kivy framework easier, but it can be used independently - even with other GUI frameworks.

For Android, buildozer will automatically download and prepare the build dependencies. For more information, see Android SDK NDK Information.

[!NOTE] This tool is unrelated to the online build service,

Installing Buildozer with target Python 3 (default):

Buildozer incorporates a number of technologies, and has a complicated dependencies, including platform dependencies outside of Python.

This means installation is more than a simple pip install; many of our support requests are related to missing dependencies.

So, it is important to follow the instructions carefully.

Please see the Installation documentation specific to this version.

Buildozer Docker image

A Dockerfile is available to use buildozer through a Docker environment.

  • Build with:
docker build --tag=kivy/buildozer .

For macOS, build with:

docker buildx build --platform=linux/amd64 -t kivy/buildozer .
  • Run with:

DockerHub contains an obsolete Docker image for Buildozer. It is deprecated. Build your own.

Example Build with Caching

  • Build and keep downloaded SDK and NDK in ~/.buildozer directory:
docker run -v $HOME/.buildozer:/home/user/.buildozer -v $(pwd):/home/user/hostcwd kivy/buildozer android debug

Examples of Buildozer commands

# buildozer target command
buildozer android clean
buildozer android update
buildozer android deploy
buildozer android debug
buildozer android release

# or all in one (compile in debug, deploy on device)
buildozer android debug deploy

# set the default command if nothing set
buildozer setdefault android debug deploy run


Run buildozer init to have a new buildozer.spec file copied into the current working directory. Edit it before running your first build.

See buildozer/default.spec for the template.

Default config

You can override the value of any buildozer.spec config token by setting an appropriate environment variable. These are all of the form $SECTION_TOKEN, where SECTION is the config file section and TOKEN is the config token to override. Dots are replaced by underscores.

For example, here are some config tokens from the [app] section of the config, along with the environment variables that would override them.

  • title -> $APP_TITLE
  • p4a.source_dir -> $APP_P4A_SOURCE_DIR


Buildozer is MIT licensed, actively developed by a great community and is supported by many projects managed by the Kivy Organization.
