Expo start not working


#1

I have built react native app.

But error occurs after reinstalling computer OS.

If I run “expo start”, expo dev tools is opened in Chrome.
And it only shows “Starting Metro Bundler on port 19001”.
“Tunnel ready” is not appear.

How can I solve this?

In this case if I press “Run on Android device/emulator” button, it shows error like this.

Couldn't start project on Android: could not install *smartsocket* listener: cannot bind to 127.0.0.1:5037: Only one usage of each socket address (protocol/network address/port) is normally permitted. (10048)
could not read ok from ADB Server
* failed to start daemon *
error: cannot connect to daemon
