How to run react native on WSL with android emulator on Windows

Question

I have a react native expo project on WSL2 and I need to run it on an android emulator on Windows, and I am also willing to run the project using yarn start. How would I set up React Native to be able to run yarn start in WSL and run the app in an Android emulator on Windows?

Here are the steps I followed:

1. On Windows: Install WSL2, Ubuntu, and Android, also created device emulator
2. On WSL2: Installed java-8-openjdk in WSL2 (sudo apt-get install openjdk-8-jre), I already have nodejs, npm and nvm installed.
3. Installed Android SDK cmdline tools in WSL2 using these commands, and adjust directory structure as home//android-sdk/ has a few sub-directories: build-tools, cmdline-tools, licenses, platform-tools, platforms and cmdline-tools has a sub-directory: tools

sudo apt-get install unzip
wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip
unzip sdk-tools-linux-4333796.zip -d Android
rm sdk-tools-linux-4333796.zip
sudo apt-get install -y lib32z1 openjdk-8-jdk

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin
printf "\n\nexport JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64\nexport PATH=\$PATH:\$JAVA_HOME/bin" >> ~/.bashrc
cd Android/tools/bin
./sdkmanager "platform-tools" "platforms;android-26" "build-tools;26.0.3"

#on bashrc I export the following paths
export ANDROID_SDK_ROOT=/home/<user>/android-sdk
export PATH=$ANDROID_SDK_ROOT/cmdline-tools/tools/bin:$PATH
export PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools

android update sdk --no-ui
sudo apt-get install gradle
gradle -v
adb start-server

4. on .bashrc file of wsl2

   export WSL_HOST=$(tail -1 /etc/resolv.conf | cut -d' ' -f2)

   export ADB_SERVER_SOCKET=tcp:$WSL_HOST:5037

5. On Windows: Installed socat (eg. sudo apt-get install socat). Socat relays the requests from wsl2 to windows using the following command: socat -d -d TCP-LISTEN:5037,reuseaddr,fork TCP:$(cat /etc/resolv.conf | tail -n1 | cut -d " " -f 2):5037

6. on Windows: typed these commandsadb kill-server & adb.exe start-server

7. I checked the adb version on both WSL2 and Windows are the same adb --version

8. Opening the emulator on windows android.

9. running the project on WSL2 using yarn start, then type 'a' which should open the android but I end up in that error when I type 'a'.

update I also run these commands in powershell admin

iex "netsh interface portproxy delete v4tov4 listenport=3333 listenaddress=127.0.0.1" | out-null;

# GET THE WSL IP AND CHECKS IT FORMAT xxx.xxx.xxx.xxx
$WSL_CLIENT = bash.exe -c "ip addr show eth0 | grep -oP '(?<=inet\s)\d+(\.\d+){3}'";
$WSL_CLIENT -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';
$WSL_CLIENT = $matches[0];

# ADD PORTS FORWARD FROM WSL TO WINDOWS
#(With this command, windows port 3333 starts to listen port 3333 of wsl2)
iex "netsh interface portproxy add v4tov4 listenport=3333 listenaddress=127.0.0.1 connectport=3333 connectaddress=$WSL_CLIENT"

# TO CHECK ALL PORTS CONFIGURED:
netsh interface portproxy show all
