I understand that this has been asked many times before but none of the solutions work for me. Here is the screen grab of my device(android 6.0.1 samsung J210F): enter image description here

When I open localhost:8081/debugger-ui I get this message: enter image description here

So debugger is running on 8081. BUT it gives this message on console: enter image description here

The reverse tcp command has already been executed by the debugger: enter image description here

(The full error that got clipped was Error running 'RN': timeout on waiting for connection to React Native packager. Make sure you have selected 'Debug JS Remotely' from the Developer Menu. I have already selected "Debug JS Remotely" from developer menu so I don't think thats the reason.

I hope I provided all the information. Have been struggling for hours to solve this.

  • Only a short hint for something I learned the hard way: Always use "Incognito - Mode" in Chrome-Browser. Because Chrome merge the sourcecode of the page with all activated and loaded Browser-Extensions. This may give you a huge noise in the console, which caused by your Browser-Extensions, and not by your app. – suther Apr 17 '18 at 13:17

Just run the command adb reverse tcp:8081 tcp:8081 and then run react-native run-android. The problem would be solved.

Before enabling remote debugging on your emulator, open http://localhost:8081/debugger-ui in chrome. Then enable remote debugging and go back to the chrome page where you should see your console logs.

Just incase anyone comes across this, I ran into this problem and none of the above solutions worked for me.

I was building my app to my pixel 2 and trying to get chrome debugging working and kept getting this error.

What worked for me: Shake your phone to pull up the RN menu. Click on dev settings. Inside dev settings, click on 'Debug server host & port for device'

here make sure its your machine ip address followed by port 8081. If youre on a mac, you can find your machine ip by going to system preferences --> network --> and under 'status: connected' you will see the IP address info. Make sure your device and mac are on the same wifi network.

Going back to 'Debug server host & port for device' input '10.0.1.1:8081' (replace 10.0.1.1 with whatever your machine ip was).

Reload your build, and then click Debug JS remotely. These steps worked for me.

If you are trying it on your own device, shake your phone left and right to open the debugger menu. then the error goes away.
