# Buildozer action

Build your Python/[Kivy](https://github.com/kivy/kivy) applications for Android
with [Buildozer](https://github.com/kivy/buildozer). This action uses official
Buildozer [Docker image](https://github.com/kivy/buildozer/blob/master/Dockerfile),
but adds some features and patches to use in GitHub Actions.

## 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 setup.py build_ext --inplace; buildozer android debug`.

### `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](https://github.com/kivy/buildozer/tree/master) branch _(`pip install git+https://github.com/kivy/buildozer.git@master`)_.
- Set to [tag](https://github.com/kivy/buildozer/tree/1.2.0) name `1.2.0` to use specific release _(`pip install git+https://github.com/kivy/buildozer.git@1.2.0`)_.
- Set to [commit](https://github.com/kivy/buildozer/tree/94cfcb8) 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 repository root.

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

## Environment variables

You can set environment variables to change Buildozer settings. See
[Buildozer Readme](https://github.com/kivy/buildozer#default-config) for more
information.

Example (change Android architecture):

```yaml
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:

```yaml
- 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

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

## Full workflow

```yaml
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
        id: buildozer
        with:
          workdir: test_app
          buildozer_version: stable

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