Gundroid = Guix + Android ♥

Desciption

This channel contains: cli-tools, emulator and android-studio.

Originally took Android Studio launching example from Julien Lepiller (@roptat) blogpost. You can also take a look on his guix-android channel.

Setting everything up to run Android Emulator (without Android Studio)

Before lauching the emulator the followings needs to be properly packed (patchelf’ed) and expose proper binaries:

[X] cli-tools (apkanalyzer, avdmanager, lint, retrace, sdkmanager)
[ ] emulator (emulator, mksdcard)
[ ] build-tools (aapt2, apksigner, zipalign)
[ ] platform-tools (adb, etc1tool, fastboot, logcat)

(see (1) as reference)

Even having it packed propely emulator won’t work, because it would expect envvar ANDROID_HOME set propely and the content of this directory to replicate exact file-system structure (from (1)):

commandline tools bins: cmdline-tools/version/bin/
build tools bins: build-tools/version
emulator’s bins: emulator
platform-tools bins: platform-tools

This can be done by creating guix service after packing all them propely.

Launching Android Studio

Currently launching Android Studio easily from the package itself is not implemented. It can be launched in a container. Assuming you are at this channel’s root directory do the following:

Build the studio package and get it’s store path

guix build -f gundroid/studio.scm -L.
...
/gnu/store/...-android-studio-2022.1.1.19

Launch the container and bash into it

guix shell -C -F -N -L. \
    -e "(@@ (gundroid packages studio) studio)" \
    --share=$XAUTHORITY --share=/tmp/.X11-unix \
    --share=/dev/shm --expose=/etc/machine-id \
    --share=$HOME --share=/dev/kvm \
    --preserve=XAUTHORITY --preserve=DISPLAY \
    -m $PWD/gundroid/manifest.scm \
    -- bash

Go to studio’s store path being in the container and launch the studio
```
cd /gnu/store/...-android-studio-2022.1.1.19
./bin/studio.sh
    
```

But even with this the emulator inside the studio won’t work. You have to propely set up Android envvars (ANDOID_HOME and PATH) to integrate with emulator and cli-tools: see environment variables reference on android’s doc page.

The best way to make the studio work would be to add emulator and cli-tools as packages’s inputs and create separate gexp-script to automatically lauch it in a container (see nonguix steam example) with the customizable environment vars set where’d user like to have their ANDROID_HOME.
