Using the Android SDK
NixOS uses the androidenv package for building android SDKs and manually creating emulators without the use of Android Studio. Example android sdk is androidenv.androidPkgs_9_0.androidsdk
. They also include all of the SDK tools such as sdkmanager and avdmanager needed to create emulators.
The first link provides a guide for creating a custom android SDK, using a predefined SDK, and how to nixify an emulator. The second link is an extra guide that might have some helpful tips for improving your workflow.
When creating emulators with Nix's emulateApp function as mentioned in the first link, your IDE should now be able to recognize the emulator but you won't be able to run the code. To run it, view the first link on how to run the apk file in the emulator.
To run emulateApp, build it with nix-build fileName.nix
. It'll build in the folder result
. run it with ./result/bin/run-test-emulator
Creating emulators without Nix
If you don't want to nixify your emulators, you can use Android Studio and set up emulators there like a regular system.
Using sdkmanager
and avdmanager
from the Android SDK may not work given how Nix stores its files. You can use them from the Android Studio GUI.
When using machine images from the SDK, you will need to run them with steam-run
, and possibly pass extra flags, e.g.:
steam-run ~/Android/Sdk/emulator/emulator -feature -Vulkan @Pixel_5_API_33
hardware acceleration
NOTE: Whether this here is effective needs more research and confirmation. My colleague and I have seen the emulator using around 800% CPU. So far, the following has improved that on my side.
See also the nixpkgs issue where people tried to trace issues.
Add your user to the kvm
group:
{
users.users.<your-user>.extraGroups = [ "kvm" ];
}
adb setup
To enable adb
in NixOS for unprivileged users
add these lines to your configuration.nix
.
This is mandatory for all further interactions with your android device.
{
programs.adb.enable = true;
users.users.<your-user>.extraGroups = [ "adbusers" ];
}
This will add additional udev rules for unprivileged access as well as add adb to your $PATH
.
Alternatively, if you don't want to install adb globally but do want to configure the udev rules, you can:
{
services.udev.packages = [
pkgs.android-udev-rules
];
}
Use Older Platform Version
If you would like to get older platform version, you can write the following.
{ pkgs ? import <nixpkgs> {
config.android_sdk.accept_license = true;
overlays = [
(self: super: {
androidPkgs_8_0 = super.androidenv.composeAndroidPackages {
platformVersions = [ "26" ];
abiVersions = [ "x86" "x86_64"];
};
})
];
} }:
(pkgs.buildFHSUserEnv {
name = "android-sdk-env";
targetPkgs = pkgs: (with pkgs;
[
androidPkgs_8_0.androidsdk
glibc
]);
runScript = "bash";
}).env
Interaction with your Android device
adb shell on device
First open a nix-shell with the platform tools and connect your device:
$ nix-shell -p androidenv.androidPkgs.platform-tools
% adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
BH90272JCU unauthorized
Troubleshooting: no device is listed
A popup appears on your phone to allow your computer access to it. After allowing, you can:
% adb devices
List of devices attached
BH90272JCU device
% adb shell
You can also connect to an already-running adb server:
$ # For nixos < 19.03
$ # nix-shell -p androidenv.platformTools
$ nix-shell -p androidenv.androidPkgs_9_0.platform-tools
% adb connect 192.168.1.10
% adb shell
Transferring files from/to an Android device
There are two main methods for newer devices:
adb push
andadb pull
: see above.- via MTP, see the corresponding page
Android Development
Android Studio
To develop apps using Android Studio, install it to your system.
environment.systemPackages = [
pkgs.android-studio
]
By default, Android Studio has a FHS environment and by using pkgs.android-studio-full
you get the predefined Android SDK composition including (as of nixos-unstable on 2024-11-02) platforms 28-34, an emulator, many system images and the NDK.
Notice: to install Android Studio, you have to indicate accepting the EULA. If you don't, the rebuild fails and prints the EULA. The simplest way to acknowledge it is to add this line to your config:
nixpkgs.config.android_sdk.accept_license = true;
gradlew
It's possible to create a build environment (shell.nix) to use with gradlew as a FHS environment:
{ pkgs ? import <nixpkgs> {config.android_sdk.accept_license = true;} }:
(pkgs.buildFHSUserEnv {
name = "android-sdk-env";
targetPkgs = pkgs: (with pkgs;
[
androidenv.androidPkgs_9_0.androidsdk
glibc
]);
runScript = "bash";
}).env
As an alternative, it's often enough to override just the aapt2 binary for the gradle build process:
{ pkgs ? import <nixpkgs> {config.android_sdk.accept_license = true;} }:
let
androidSdk = pkgs.androidenv.androidPkgs_9_0.androidsdk;
in
pkgs.mkShell {
buildInputs = with pkgs; [
androidSdk
glibc
];
# override the aapt2 that gradle uses with the nix-shipped version
GRADLE_OPTS = "-Dorg.gradle.project.android.aapt2FromMavenOverride=${androidSdk}/libexec/android-sdk/build-tools/28.0.3/aapt2";
}
See the androidenv documentation for full examples.
Building Android on NixOS
It's possible to use nix-shell with buildFHSUserEnv to set up an environment in which it's viable to build Android without huge amounts of editing. This is an example shell.nix file.
{ pkgs ? import <nixpkgs> {} }:
let fhs = pkgs.buildFHSUserEnv {
name = "android-env";
targetPkgs = pkgs: with pkgs;

export ANDROID_JAVA_HOME=${pkgs.jdk.home}sdkmanager install avd
export LD_LIBRARY_PATH=/usr/lib:/usr/lib32
'';

in pkgs.stdenv.mkDerivation {
name = "android-env-shell";
nativeBuildInputs = [ fhs ];
shellHook = "exec android-env";
}
Android Debug Bridge
Run nix-shell -p usbutils --run "lsusb"
on your terminal to get the list of USB devices connected to your computer. Sample output (source):
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hubBus 001 Device 009: ID 138a:0010 Validity Sensors, Inc. VFS Fingerprint sensor Bus 001 Device 008: ID 13d3:3491 IMC Networks
ID 1d6b:0003
can be seen as: idVendor = 1d6b
and idProduct = 0003
.
{
programs.adb.enable = true;
services.udev.extraRules =
let
# nix-shell -p usbutils --run "lsusb"
idVendor = "1d6b"; # Change according to the guide above
idProduct = "0003"; # Change according to the guide above
in

# add user to adbusers group
users.users.myUser = {
isNormalUser = true;
extraGroups = [ "adbusers" ];
};
}
