Buildozer

Buildozer is a tool for creating application packages easily.

The goal is to have one "buildozer.spec" file in your app directory, describing your application requirements and settings such as title, icon, included modules etc. Buildozer will use that spec to create a package for Android, iOS, Windows, OSX and/or Linux.

Buildozer currently supports packaging for Android via the python-for-android project, and for iOS via the kivy-ios project. iOS and OSX are still under work.

For Android: please have a look at Android-SDK-NDK-Informations. Please note that the default SDK/NDK coded in Buildozer works for target Python 2. For target Python 3 see Installing Buildozer with target Python 3 (CrystaX). For host Python, both versions are seamlessly supported.

We provide a ready-to-use Virtual Machine for Virtualbox.

Note that this tool has nothing to do with the eponymous online build service buildozer.io.

Installing Buildozer with target Python 2 (default):

  1. Install buildozer:

    # via pip (latest stable, recommended)
    sudo pip install buildozer
    
    # latest dev version
    sudo pip install https://github.com/kivy/buildozer/archive/master.zip
    
    # git clone, for working on buildozer
    git clone https://github.com/kivy/buildozer
    cd buildozer
    python setup.py build
    sudo pip install -e .
    
  2. Go into your application directory and run:

    buildozer init
    # edit the buildozer.spec, then
    buildozer android debug deploy run
    

Installing Buildozer with target Python 3 (CrystaX):

After following the steps above to install buildozer and generate the default spec file, you need to setup Crystax NDK as described below.

  1. Download and extract the Crystax NDK somewhere (~/.buildozer/crystax-ndk is one option): https://www.crystax.net/en/download

  2. Make sure the following lines are in your buildozer.spec file.:

    # Require python3crystax:
    requirements = python3crystax,kivy
    
    # Point to the directory where you extracted the crystax-ndk:
    android.ndk_path = <Your install path here.  Use ~ for home DIR>
    
  3. Finally, build, deploy and run the app on your phone:

    buildozer android debug deploy run
    

Buildozer Docker image

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

  1. Build with:

    docker build --tag=buildozer .
    
  2. Run with:

    docker run --volume "$(pwd)":/home/user/hostcwd buildozer --version
    

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

Usage

Usage:
    buildozer [--profile <name>] [--verbose] [target] <command>...
    buildozer --version

Available targets:
  android        Android target, based on python-for-android project
  ios            iOS target, based on kivy-ios project
  android_old    Android target, based on python-for-android project (old toolchain)

Global commands (without target):
  distclean          Clean the whole Buildozer environment.
  help               Show the Buildozer help.
  init               Create a initial buildozer.spec in the current directory
  serve              Serve the bin directory via SimpleHTTPServer
  setdefault         Set the default command to run when no arguments are given
  version            Show the Buildozer version

Target commands:
  clean      Clean the target environment
  update     Update the target dependencies
  debug      Build the application in debug mode
  release    Build the application in release mode
  deploy     Deploy the application on the device
  run        Run the application on the device
  serve      Serve the bin directory via SimpleHTTPServer

Target "android_old" commands:
  adb                Run adb from the Android SDK. Args must come after --, or
                     use --alias to make an alias
  logcat             Show the log from the device

Target "ios" commands:
  list_identities    List the available identities to use for signing.
  xcode              Open the xcode project.

Target "android" commands:
  adb                Run adb from the Android SDK. Args must come after --, or
                     use --alias to make an alias
  logcat             Show the log from the device
  p4a                Run p4a commands. Args must come after --, or use --alias
                     to make an alias

buildozer.spec

See buildozer/default.spec for an up-to-date spec file.

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
  • package.name -> $APP_PACKAGE_NAME
  • p4a.source_dir -> $APP_P4A_SOURCE_DIR

Buildozer Virtual Machine

The current virtual machine (available via https://kivy.org/downloads/) allow you to have a ready to use vm for building android application.

Using shared folders

If the Virtualbox Guest tools are outdated, install the latest one:

  • in the Virtualbox: Devices -> Install Guest Additions CD images
  • in the guest/linux: Go to the cdrom and run the installer
  • reboot the vm

VirtualBox filesystem doesn't support symlink anymore (don't try the setextradata solution, it doesn't work.). So you must do the build outside the shared folder. One solution:

  • sudo mkdir /build
  • sudo chown kivy /build
  • In your buildozer.spec, section [buildozer], set build_dir = /build/buildozer-myapp

Using your devices via the VM

There is a little icon on the bottom left that represent an USB plug. Select it, and select your android device on it. Then you can check:

  • buildozer android adb -- devices

If it doesn't, use Google. They are so many differents way / issues depending your phone that Google will be your only source of information, not us :)
