React Native setup

I'll follow tutorial on ReactNative.dev

# Assuming that you have Node 12 LTS or greater installed, you can use npm to install the Expo CLI command line utility
$ sudo npm install -g expo-cli
# Then run the following commands to create a new React Native project called "AwesomeProject"
$ expo init AwesomeProject

cd AwesomeProject
$ npm start # you can also use: expo start

Select Run on Android device/emulator in expo web client

FAQ

For some reason, EXPO GO closes after trying to connect with port 19000, it gives a Java error, but after investigating, I think it may have to do with an option within the WSA settings that does not allow me to enable the wireless debugging option. It's a button that, no matter how much I press, it doesn't activate. Any other ideas?

[ADB] Couldn't reverse port 19000: adb: error: cannot bind listener: Address already in use

Can anyone help me? I can see the device connected when I type adb devices, nut when I try to run the emulator i get a lot of errors

Set environment path in your bash profile:
`export ANDROID_HOME=/home/xxxx/Android
export ANDROID_SDK_ROOT=/home/xxxx/Android

PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools
PATH=$PATH:$ANDROID_HOME/bin
