React native Cannot connect to react-devtools using android simulator

Question

I execute the project with react-native run-android and in another terminal, i do:

npm run react-devtools

and it opens the new window of electron that says:

The react native app it will open in a few seconds...

but nothing happens.

I put in the simulator toggle inspector with Ctrl + m and i can see in networks that it makes a request to http://localhost:8097 and the result is it fails to connect and keeps trying with the same result.

The window of electron that is open it says that it wait connections to the port 8097 so i can see is trying to connect but with no results!

Answer 1

You need to run this command in a new terminal adb reverse tcp:8097 tcp:8097

Answer 2

react-devtools v4 is incompatible with react-native

try version 3 instead of version 4: npm install -d -g [email protected], it's worked for me.
