Anbox

Linux Containers

Anbox は GNU/Linux ディストリビューションで Android を実行するためのコンテナベースのソフトウェアです。

Prerequisite

ノート: The dkms modules do not work on kernels ≥5.7 anymore. Follow the instructions below instead. For older kernels see Old kernels.

You need to run a kernel which comes with the ashmem and binder modules. They are not part of Arch Linux's default kernel (linux), thus you need to install a kernel which ships these modules. You might also need to configure your bootloader to use a different kernel. You have multiple options:

Using Linux-Zen

The linux-zen kernel includes the necessary modules. This might be the most comfortable way, as you do not have to compile the kernel (which takes a long time) and will receive updated versions regularly.

Building a kernel

Alternatively, you can recompile the linux kernel — or other kernel packages (>=5.7) — with the necessary options. Please read Kernel#Compilation and Necessary config options below. You can also build a kernel package that already includes the specific patches from AUR, see AUR search "linux+anbox".

Necessary config options

Modules can either be compiled into the kernel (y), into modules (m), or not at all (n). Also, not all combinations in the config are possible, and some options will require other options. The config options below will compile ashmem and binder as modules, while the last option specifies that there will be three devices created in the /dev/ directory, when the binder module is loaded.

CONFIG_ASHMEM=m 
CONFIG_ANDROID=y
CONFIG_ANDROID_BINDER_IPC=m
CONFIG_ANDROID_BINDERFS=n
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"

When building a kernel from the AUR, one can do it with these steps:

run makepkg --nobuild, which will download the sources, verify and extract them and run the prepare() function.
edit the .config file (with the dot in the filename), which is located at the base of the kernel directory.
at the end of the prepare() function was probably a command which regenerates the makefiles with information from the config, possibly make olddefconfig. Move that to the build() function, or execute it yourself.
run makepkg --noextract, which will continue from the place where makepkg --nobuild stopped.

config using binderfs

Not everybody was happy with the binder module in Linux. To address the issues, binderfs was created. One has to choose between the old and the new way when compiling the kernel. With the options below one will use binderfs instead. With the kernel sources comes also a simple script to set config options. It will not do dependency checks, just like when editing the config by hand. When being in the same directory where the .config file lies, one can execute the following commands:

scripts/config --module  CONFIG_ASHMEM
scripts/config --enable  CONFIG_ANDROID
scripts/config --enable  CONFIG_ANDROID_BINDER_IPC
scripts/config --enable  CONFIG_ANDROID_BINDERFS
scripts/config --set-str CONFIG_ANDROID_BINDER_DEVICES ""

This script is handy when building a kernel from the AUR, as it is enough to insert these lines at the right place in the PKGBUILD.

Booting the new kernel

Please refer to the wiki page of your bootloader, to find out, how to boot with the new kernel. Booting into a newer kernel (version) is one of the few occasions when you have to reboot a Linux system. You should do that before starting Anbox.

インストール

anbox-git^AUR, anbox-image^AUR (もしくは Google のアプリや houdini も使いたい場合は anbox-image-gapps^AUR), anbox-modules-dkms-git^AUR^{[リンク切れ: パッケージが存在しません]}, anbox-bridge^AUR^{[リンク切れ: パッケージが存在しません]} をインストールしてください。

最新の 5.1 カーネルでは anbox-modules-dkms-git^AUR^{[リンク切れ: パッケージが存在しません]} の PKGBUILD にパッチ [1] を適用しないと必要な binder モジュールがコンパイルできません。

以下のサービスを起動・有効化してください:

anbox-container-manager.service

DKMS モジュールを使うのにコンピュータを再起動したくない場合、手動でロードすることができます:

# modprobe ashmem_linux
# modprobe binder_linux

Network

Via NetworkManager

If you are using NetworkManager you can use it to configure the networking. Execute the following command to create the bridge connection:

$ nmcli con add type bridge ifname anbox0 -- connection.id anbox-net ipv4.method shared ipv4.addresses 192.168.250.1/24

ifname anbox0 specifies the bridge interface name, in this case anbox0. Do not change this as Anbox will only detect the bridge interface if it is named anbox0.
connection.id anbox-net specifies the name of the connection to be anbox-net when it appears in NetworkManager. You can change this if you wish.
ipv4.method shared instructs NetworkManager to create a NAT network and route outgoing packets according to the system routing rules. For that, the dnsmasq package is required. dnsmasq does not needs to be configured or be started as systemd service, it will be used behind the scenes by NetworkManager — if it is not available, this step will fail silently. You can leave this and the ipv4.addresses parameter out if you wish to attach the Anbox container directly to a specific network, see Network bridge#With NetworkManager. If you choose this option, you must also change the network configuration of the container in anbox-container-manager.service, see the next bullet point.
ipv4.addresses 192.168.250.1/24 specifies the default gateway and subnet of the NAT network. If you wish to change this (e.g. to 192.168.42.1/24) you must also indicate the new subnet to anbox in the anbox-container-manager.service using: --container-network-address=192.168.42.2/24 --container-network-gateway=192.168.42.1

NetworkManager will automatically setup the bridge every reboot so you only need to execute the command once.

Via systemd-networkd

The package anbox-git^AUR provides configuration files for systemd-networkd in /usr/lib/systemd/network/ to enable networking in anbox. Therefore, you can start/enable systemd-networkd before starting anbox-container-manager.service.

Via anbox-bridge script

Alternatively you can use the anbox-bridge script used by the project. You must execute anbox-bridge every time before starting anbox-container-manager.service in order to get network working in Anbox. The easiest solution for that is to create a drop-in file for the service.

/etc/systemd/system/anbox-container-manager.service.d/enable-anbox-bridge.conf

[Service]
ExecStartPre=/usr/bin/anbox-bridge start
ExecStopPost=/usr/bin/anbox-bridge stop

使用方法

anbox 内でネットワークを使えるようにするため anbox を起動する前に毎回 anbox-bridge を実行してください。

adb を使ってデバッグしたい場合、android-tools をインストールしてください。

$ adb shell
