A Dockerfile for provisioning a build environment for Android apps written in Haskell

Introduction

This repository contains a Dockerfile for building a simple HelloWorld written in Haskell for Android. The dockerfile is built upon sseefried's docker-epidemic-build-env but without all the dependencies specific to his game Epidemic. It includes a slightly modified version of CJ van den Berg's [android-haskell-activity](https://github.com/neurocyte/android-haskell-act ivity), which also runs on iOS devices, it's repository can be found here.

Installation

Please ensure that you are using at least Docker version 1.6. Check with docker version.

(Optional) Build debian-wheezy-ghc-android

You probably only want to do this if for some reason you can't download sseefried/debian-wheezy-ghc-android from the Docker Hub registry. It's rather large at 1.1G.

Follow the instruction in the README.md here.

Once you've done that you'll need to tag the resulting image as sseefried/debian-wheezy-ghc-android locally to build the image this Dockerfile specifies.

Build with Docker

At the command line simply type:

$ docker build .

This will take a while to build. First, unless you performed the previous step, Docker must download the image sseefried/debian-wheezy-ghc-android (about 1.1G). It will then download, clone and build a bunch of libraries. Go get a coffee, drink it slowly, go for a long walk and then come back. Once it's finished type:

$ docker images

You will get something like:

REPOSITORY                            TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
<none>                                <none>              3b16cf90e485        6 minutes ago       5.923 GB
...

You can tag the image with something memorable like:

docker tag <image id> epidemic-build-env

You now have two options for building and installing Epidemic.

Option A: Build, copy APK and install

You can simply run an interactive shell and build the APK inside a running container.

$ docker run -it epidemic-build-env /bin/bash
androidbuilder@283089ad80b9:~/build$ cd CPConsoleApp
androidbuilder@283089ad80b9:~/build/CPConsoleApp$ ./build-android.sh

The adb tool is not installed in the image so once you have built the APK you will want to copy the APK to your local machine (which presumably has adb installed in it).

Keep the container running. In a fresh shell (in another terminal window) type:

 $ docker ps

You'll get something like:

CONTAINER ID        IMAGE                       COMMAND             CREATED              STATUS                  PORTS               NAMES
d4a82703a3a9        epidemic-build-env:latest   "/bin/bash"         About a minute ago   Up 57     seconds                           dreamy_ptolemy

This will give you a container ID (d4a82703a3a9 or dreamy_ptolemy here).

 $ docker cp dreamy_ptolemy:/home/androidbuilder/build/CPConsoleApp/bin/CPConsoleApp-debug.apk .

You can now install this APK with

 $ adb install -r CPConsoleApp-debug.apk
