    First make sure your metro bundle is running on 8081 port.

    yarn start –port 8081

    adb reverse tcp:8081 tcp:8081

    Try this above 2 commands, I hope this will help you out!

    You need to allow your phone/simulator to talk to Metro Bundler.

    There is a command line tool called ‘adb’. You need to install that into your local terminal. Then do yourself a favor and add it to your $PATH so you can call adb from anywhere. In my case I use zsh so I edited my ~/.zshrc file (your file might be ~/.bash_profile or other).

    export PATH=$PATH:/Users/{my_user_directory}/Library/Android/sdk/platform-tools/

    Then source the file: source ~/.zshrc

    Now run in your terminal: adb reverse tcp:8081 tcp:8081

    I usually run this right after I start up the simulator but before my app actually loads up.
