I am working with react native, and would like to switch adb to wifi for easier debugging.
I connect my device using usb, then type these commands.
adb t
When I am facing the same issues than doing like below:
1) kill your process of 8081 port for using this command : kill -9 $(lsof -t -i:8081)
2) Reset your adb connection with : adb usb
if you want to run via wifi then connect your device again : adb tcpip 5555
3) Start your npm : npm start
4) Then after you can run your react native app : react-native run-android
and it's works fine for me.
