Go is used for the networking, json parsing, caching and timer. Go source: https://github.com/ChrisSmith/libcats

Quick Setup for Go/Android compilation

Update Android Tools

Install NDK (https://developer.android.com/tools/sdk/ndk/index.html)

Setup Android toolchain

./build/tools/make-standalone-toolchain.sh  --arch=arm  --platform=android-19 --system=darwin-x86_64 --toolchain=arm-linux-androideabi-4.8 --install-dir=$NDK_ROOT

Update Go to 1.4 (clone from master if you use Android 5.0+. https://github.com/golang/go)

go get golang.org/x/mobile/app

Cross compile gcc for android

cd /usr/local/src // Go is typically installed here on OSX
CC=clang ./make.bash
CC_FOR_TARGET=$NDK_ROOT/bin/arm-linux-androideabi-gcc CGO_ENABLED=1 GOOS=android GOARCH=arm GOARM=7 ./make.bash

optionally override gcc in your profile

See https://github.com/ChrisSmith/GoCats/blob/master/genbindings.sh on how to compile and generate the bindings between the languages
