Android in Container

AIC (Android in Container) means runing Android inside a container on
Linux. RK3588 Linux can use docker to run Android and support running
multiple Androids at the same time.

Cluster-Server with AIC can increase the amount of Androids, really
helpful in cloud-mobile and cloud-gaming.

Here are some firmwares for testing:

Usage

Notice:

The host OS is Ubuntu Minimal without desktop, so using debug serial,
ssh, adb shell etc. to interact.

Interaction with Android is through network adb and screen mirroring
application like scrcpy, not by mouse/keyboard.

Operation AIC requires the following knowledge: basic Linux commands,
docker commands, adb commands.

Create Containers

Copy the "container" dir to the /userdata/ of host device (RK3588),
use the script "aic.sh" inside to deploy:

Please connect the device to the Internet, and init env at first use:

   cd /userdata/container
   ./aic.sh -i

After init, copy android container firmware to /userdata/container/
(There's already a firmware in it)

Run "./aic.sh -r <android_container_firmware.tgz> " to deploy.

   # For example:
   ./aic.sh -r rk3588_docker-android12-userdebug-super.img-20231128.1932.tgz 3

Default use docker0 network and port mapping:

   <host ip>:1100 --> <container 0>:5555
   <host ip>:1101 --> <container 1>:5555
   ......

For more please read aic.sh

Connect to Containers

In the same local network, use any PC with adb to connect.

   adb connect <host ip>:<port>

   # After connection
   # Start scrcpy
   scrcpy -s <host ip>:<port>

We skipped the tutorial of installing adb and scrcpy, please google it
if you need.

Manage Containers

Use common docker commands to manage containers.

   # Check all containers
   root@firefly:~# docker ps -a
   CONTAINER ID   IMAGE            COMMAND                  CREATED      STATUS                    PORTS     NAMES
   cad5a331dea9   rk3588:firefly   "/init androidboot.h…"   6 days ago   Exited (137) 6 days ago             android_1
   37f60c3b6b80   rk3588:firefly   "/init androidboot.h…"   6 days ago   Up 13 seconds                       android_0

   # Start/Stop containers
   docker start/stop <NAMES>

   # Connect to Android shell(run exit to return)
   docker exec -it <NAMES> sh

   # Delete containers
   docker rm <NAMES>

Performance

Run this cmd as root to enable performance mode to get better
experience:

   # It is normal to get an "Invalid argument", ignore it
   root@firefly:~# echo performance | tee $(find /sys/devices -name *governor)
   performance
   tee: /sys/devices/system/cpu/cpuidle/current_governor: Invalid argument

Enter Android terminal or use adb shell to run this cmd can print the
game fps:

   # Notice: This cmd prints fps only when the game is running
   setprop debug.sf.fps 1;logcat -s SurfaceFlinger

One RK3588 using AIC running two Genshin Impact with highest graphic
setting at the same time can reach 35+ fps:
