React Native adb reverse error: more than one device
Solution 1
When I am facing the same issues than doing like below:
- Restart adb by issuing adb kill-server followed by adb start-server in a command prompt.
- Disable and re-enable USB debugging on the phone Rebooting the phone if it still doesn't work.
my issues have been resolved with these steps.

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.

Open Task Manager > search "qemu" > kill it. I using Android emulator, work for me! Good luck :)

I am learning react native. I can successfully connect my android device using USB. But when I try to connect it using wifi, it gives me an error.
$ adb kill-server $ adb version Android Debug Bridge version 1.0.40 Version 4986621 Installed as /home/subtleseeker/Android/Sdk/platform-tools/adb $ adb connect 172.26.40.211:8081 * daemon not running. starting it now on port 5037 * * daemon started successfully * connected to 172.26.40.211:8081 $ adb devices List of devices attached 172.26.40.211:8081 device $ react-native run-android JS server already running.

In the
Dev settings
of the app, I have configuredDebug server host & port for device
to the ip address of my computer as172.26.43.71:8081
. Also it is clear from the output, that the connection was successful and the apk is installed.I can't see how to resolve this error:
error: more than one device/emulator
. Any help is appreciated.

Brijesh Goswami almost 5 yearsThen you need to R&D on port because it is a port-related issue so you need to release one port before using another.
