Display Android Studio GUI from Docker container while SSH tunneling through headless Ubuntu server

I was able to figure this out -- hopefully it helps someone else:

Step 1: Enable X11 forwarding on the server that hosting the Docker container

Make sure /etc/ssh/sshd_config contains the following line:
```
X11Forwarding yes
```
SIGHUP sshd to pick up the change
```
cat /var/run/sshd.pid | xargs kill -1
```
Verify xauth if installed on the server
```
which xauth
```
If it's not, then use your package manager to install it.

Step 2: SSH into the server hosting the Docker container

From Linux, your ssh command needs to include the -X option. Example:
```
ssh -X user@<IP_OF_DOCKER_SERVER>
```
From Windows (via PuTTY):
- Windows needs an X server installed; install XMing and ensure it's running.
- In PuTTY, go to 'Connection' > 'SSH' > 'X11' and check the box next to 'Enable X11 Forwarding', then connect to the server

Step 3: Run the docker run command from the SSH'd terminal

docker run -it --rm   --net=host   -v "$HOME/.Xauthority:/root/.Xauthority:rw"   -e DISPLAY="$DISPLAY"  android-studio

Note: xorg-server does not need to be installed on the Docker container.
