Buildozer action

Build your Python/Kivy applications for Android with Buildozer. This action uses official Buildozer Docker image, but adds some features and patches to use in GitHub Actions.

Full workflow

Full workflow with uploading binaries as artifact.

name: Build
on: [push, pull_request]

jobs:
# Build job. Builds app for Android with Buildozer
build-android:
  name: Build for Android
  runs-on: ubuntu-latest

  steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Build with Buildozer
      uses: ArtemSBulgakov/buildozer-action@v1

Full workflow with uploading binaries to branch

Builds app and uploads to the data branch. Also copy .ci/move_binary.py script and create data branch as described above.

name: Build
on:
  push:
    branches-ignore:
      - data
      - gh-pages
    tags:
      - '**'
  pull_request:

      - data
      - gh-pages

jobs:
  # Build job. Builds app for Android with Buildozer
  build-android:
    name: Build for Android
    runs-on: ubuntu-latest

    steps:

        with:
          name: package
          path: ${{ steps.buildozer.outputs.filename }}

      - name: Checkout
        uses: actions/checkout@v2
        with:
          path: data
          ref: data # Branch name

      - name: Set up Python
        uses: actions/setup-python@v2
        with:
          python-version: 3.7
          architecture: x64

      - name: Push binary to data branch
        if: github.event_name == 'push'
        run: python master/.ci/move_binary.py "${{ steps.buildozer.outputs.filename }}" master data

Examples

You can search GitHub for repositories that use this action.

Some great examples:

• kivymd/KivyMD
  • build several demo apps
  • push binaries to branch at another repository
  • push binaries by the account of bot (GitHub user)
  • set numeric version with environment variable

Inputs

command

Required Command to start Buildozer.

• Default: buildozer android debug (iOS and OSX is not supported because Docker cannot run on MacOS).
• For more commands use ; as delimiter: python3 pre_buildozer.py; buildozer android debug.

repository_root

Required Path to cloned repository.

• Default: . (GitHub workspace).
• Set to directory name if you specified path for actions/checkout action.

workdir

Required Working directory where buildozer.spec is located.

• Default: . (top directory).
• Set to src if buildozer.spec is in src directory.

buildozer_version

Required Version of Buildozer to install.

• Default: stable (latest release on PyPI, pip install buildozer).
• Set to master to use master branch (pip install git+https://github.com/kivy/buildozer.git@master).
• Set to tag name 1.2.0 to use specific release (pip install git+https://github.com/kivy/buildozer.git@1.2.0).
• Set to commit hash 94cfcb8 to use specific commit (pip install git+https://github.com/kivy/buildozer.git@94cfcb8).
• Set to git+ address git+https://github.com/username/buildozer.git@master to use fork.
• Set to directory name ./my_buildozer to install from local path (pip install ./my_buildozer).
• Set to nothing '' to not install buildozer

Outputs

filename

Filename of built package relative to GITHUB_WORKSPACE.

• Example: master/test_app/bin/testapp-0.1-armeabi-v7a-debug.apk

Environment variables

You can set environment variables to change Buildozer settings. See Buildozer Readme for more information.

Example (change Android architecture):

env:
  APP_ANDROID_ARCH: armeabi-v7a

Caching

You can set up cache for Buildozer global and local directories. Global directory is in root of repository. Local directory is in workdir.

• Global: .buildozer-global (sdk, ndk, platform-tools)
• Local: test_app/.buildozer (dependencies, build temp, not recommended to cache)

I don't recommend to cache local buildozer directory because Buildozer doesn't automatically update dependencies to latest version.

Use cache only if it speeds up your workflow! Usually this only adds 1-3 minutes to job running time, so I don't use it.

Example:

- name: Cache Buildozer global directory
  uses: actions/cache@v2
  with:
    path: .buildozer_global
    key: buildozer-global-${{ hashFiles('test_app/buildozer.spec') }} # Replace with your path

Example usage

- name: Build with Buildozer
  uses: ArtemSBulgakov/buildozer-action@v1
  id: buildozer
  with:
    command: buildozer android debug
    workdir: src
    buildozer_version: stable

Uploading binaries

As artifact

You can upload binary as artifact to run. You will be able to download it by clicking on "Artifacts" button on run page (where you see logs).

- name: Upload artifacts
  uses: actions/upload-artifact@v2
  with:
    name: package
    path: ${{ steps.buildozer.outputs.filename }}

To branch

Artifacts use GitHub Storage and you have to pay for private repositories when limit exceeded. Another way to upload binary is pushing it to branch in your repository.

Copy .ci/move_binary.py script, edit it if you want and add this to your workflow:

- name: Checkout
  uses: actions/checkout@v2
  with:
    path: data
    ref: data # Branch name

- name: Set up Python
  uses: actions/setup-python@v2
  with:
    python-version: 3.7
    architecture: x64

- name: Push binary to data branch
  if: github.event_name == 'push'
  run: python master/.ci/move_binary.py "${{ steps.buildozer.outputs.filename }}" master data bin

Also you need to create data branch:

git checkout --orphan data
echo # Branch `data` > README.md
git add README.md
git commit -m "Add Readme"
git push origin data

Action versioning

Currently it is recommended to use v1 tag. This tag updates when new v1.x.x version released. All v1 versions will have backward compatibility. You will get warning when v2 will be released.

How to build packages locally

Use official Buildozer's Docker image (repository).
