adb -s 192.168.1.6:5555 … error: more than one device/emulator

Question

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         


        

Answer 1

I made two changes to the steps to get this working.

1) BEFORE disconnecting the wire from my phone, I ran adb reverse tcp:8081 tcp:5555 (note the 5555 port number for the phone) and adb connectMY.PHONE.IP.ADDRESS:5555` (with port number).

Only now did I disconnect the wire.

Then I installed the app, although it probably would work if the app was already installed.

2) After the app was installed and I was getting errors "Unable to load Script” and “Could not connect to development server”,

• opened the developer menu (shake the phone with the React Native app open) and selected “Dev Settings”. Selected “Debug server host & port for device” from the menu.
• In the window on my phone I entered MY.COMPUTER.IP.ADDRESS:8081

Now I could open/close the app for a reload, and shake -> debug JS remotely.

Answer 2

Simple, Start task manager and kill adb.exe process and run adb devices command

Answer 3

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.
