go4droid

To build an android app (with go bindings) in Docker

This Dockerfile was specifically written to build golang.org/x/mobile/example/bind/android (with golang.org/x/mobile/cmd/gomobile) but it should be possible to reuse or adapt it to build other android apps with go bindings (or even without).

The docker image is hosted at mpl7/go4droid.

usage example:

docker build -t go4droid . # or docker pull mpl7/go4droid
mkdir $HOME/.gradle # for caching
go get -d golang.org/x/mobile/example/bind/...
cd $GOPATH/src/golang.org/x/mobile/example/bind/android
docker run --rm -v "$PWD":/home/gopher/project -v $HOME/.gradle:/home/gopher/.gradle -w /home/gopher/project --name go4droid -i -t go4droid /bin/bash
gomobile bind -o app/hello.aar -target=android golang.org/x/mobile/example/bind/hello
gradle wrapper --gradle-version 4.4 # only needed once, to generate the gradle wrapper.
./gradlew assembleDebug
