OK, closing, solved it by running adb usb.

I want to debug my react native android app using my android device(Oreo).
adb -s <device name> reverse tcp:8081 tcp:8081
the above command gives me "adb.exe: error: cannot bind listener: Address already in use" error.
if i search for port process with command netstat -anbo | findStr "8081" It shows nothing.

the above command gives me "adb.exe: error: cannot bind listener: Address already in use" error.

I solved this by running adb usb first then adb reverse tcp:8081 tcp:8081. Hope this helps you!
