Unable to debug in device

Question

Hello I'm new to react native. and i'm trying to debug the code with real device. But every time I'm debug I'm getting an error :

unable to connect with remote debugger Failed to connect to localhost/127.0.0.1:8081

this on my mobile screen. Any help will be appreciated.

Please add a screenshot of the error and confirm that the device and packager are on same network. — Suraj Malviya, Dec 21 '18 at 06:11

There could be several cases where you can't connect to debugger:

Device and host machine definitely should be on the same network. Either connect your mobile to your PC's network or your pc to the mobile hotspot.
In some cases on real devices, you might need to run adbe reverse command:
```
adb reverse tcp:8081 tcp:8081
```
Uninstall the app, stop the packager, and restart the packager with reset cache option:
```
npm start -- --reset-cache
```
And then, run it on device again.
