# Android Development Container

This sets up development containers for Expo and Flutter using
the Android SDK. The Dockerfile is derived from parts of [thyrlian/android-sdk](https://github.com/thyrlian/AndroidSDK), with expo and flutter development
infrastructure configured as well.

## Build the Android SDK base container

This will seed the base container with an initial version of the Android SDK.
After it is created, the SDK is copied to a volume bind mount on the host to
allow multiple containers to use the same base SDK, as well as to perform
SDK updates, upgrades, and additional package installations.

```bash
docker compose build
```

## Seed the flutter repository

```
git clone https://github.com/flutter/flutter.git
```

## Copy the base SDK to the mounted 'sdk' directory

```bash
docker compose run -it --rm \
    android-dev-container -- \
    bash -c 'cp -a $ANDROID_HOME/. /sdk/'
```

## Install packages into SDK

The following will install Android platform 35:

```bash
ANDROID_PLATFORM=35
docker compose run -it --rm \
    android-dev-container -- \
    sdkmanager \
        "build-tools;${ANDROID_PLATFORM}.0.0" \
        "platforms;android-${ANDROID_PLATFORM}"
```

At this point, ./AndroidSDK contains the latest SDK. The docker-compose.yml
for the android-dev-container will mount ./AndroidSDK to /opt/android-sdk.

## To seed a new project (once per project)

```bash
PROJECT=foo
PROJECT_TYPE=expo # flutter
./seed.sh "${PROJECT_TYPE}" "${PROJECT}"
```

## To develop

```bash
PROJECT=foo
PROJECT_TYPE=expo
./develop.sh "${PROJECT_TYPE}" "${PROJECT}"
```

## To access the shell of the running project

```bash
PROJECT=foo
./shell.sh "${PROJECT}"
```

## To stop development container

```bash
docker compose stop "${PROJECT}"
```
