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
<http://github.com/kivy/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-Information
<https://github.com/kivy/kivy/wiki/Android-SDK-NDK-Information>`_. Please note that
the default SDK/NDK coded in Buildozer works for target Python 2.
For target Python 3, use appropriate SDK/NDK as per the documentation, and ensure you
have `python3` in your requirements.
You can still use Crystax Python 3, see `Installing Buildozer with target Python 3
(CrystaX) <#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 <https://kivy.org/#download>`_.

Note that this tool has nothing to do with the eponymous online build service
`buildozer.io <http://buildozer.io />`_.

Installing Buildozer with target Python 3 (default):
----------------------------------------------------

#. 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 .

#. Go into your application directory and run::

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

Installing Buildozer with target Python 2:
-----------------------------------------

#. Follow the same installation and buildozer init as Python 3

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

    # Changes python3 to python2
    requirements = python2,kivy

#. Finally, build, deploy and run the app on your phone::

    buildozer android debug deploy run
    
    
Installing Buildozer with target Python 3 (CrystaX, deprecated):
----------------------------------------------------------------

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

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

#. 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>

#. 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.

#. Build with::

    docker build --tag=buildozer .

#. 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>...

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

buildozer.spec
--------------

See `buildozer/default.spec <https://raw.github.com/kivy/buildozer/master/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``

Note: config tokens must first be defined in `buildozer.spec` before they can be overridden.

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 :)
