Due to licensing limitations, OpenAL should be dynamically loaded. Android apps that needs to import the audio package needs to be packed with libopenal.so as an extenal lib dependency. Instructions to build OpenAL for Android is available at http://repo.or.cz/w/openal-soft.git/blob/HEAD:/XCompile-Android.txt The packed libopenal.so is exported to /data/data/<package_name>/lib/libopenal.so at installation. The audio package dlopens libopenal.so from this location and dlsym to dispatch the OpenAL functions.

Go support for Mobile devices
The Go mobile repository holds packages and build tools for using Go on Android.
This is early work and the build system is a bumpy ride. Building a binary for Android requires using a Go cross compiler and an external linker from the NDK.
For now, the easiest way to setup a build environment is using the provided Dockerfile:
docker pull golang/mobile
Get the sample applications.
go get -d golang.org/x/mobile/example/...
In your app directory under your $GOPATH, copy the following files from either
the golang.org/x/mobile/example/basic
or golang.org/x/mobile/example/libhello
apps:
AndroidManifest.xml
all.bash
build.xml
jni/Android.mk
make.bash
Start with basic if you are writing an all-Go application (that is, an OpenGL game)
or libhello if you are building a .so file for use from Java via
gobind. Edit the files to change
the name of your app.
To build, run:
docker run -v $GOPATH/src:/src golang/mobile /bin/bash -c 'cd /src/your/project && ./make.bash'
Note the use of -v option to mount $GOPATH/src to /src of the container. The above command will fail if the -v option is missing or the specified volume is not accessible from the container.
When working with an all-Go application, this will produce a binary at
$GOPATH/src/your/project/bin/name-debug.apk. You can use the adb tool to install
and run this app. See all.bash for an example.
