react-native reload doesnt work

Issue

I can't be sure it happened because of that but I updated my project name using react-native-rename and rebuild the project couple of hours later. Since then I cant reload my project on device.

Note On simulator it works , not working only on real device. Running npm-start return :

Looking for JS files in
   /Users/Project/Client 


Metro Bundler ready.

Loading dependency graph, done. 

and never updating no matter what. I tried to look for .lock inside .git as suggested here #4357 but I can't find the .git directory so I believe it isnt the issue.

I also tried rm -rf /usr/local/var/run/watchman && brew uninstall watchman && brew install watchman as suggested here #10889 without any luck.

Along the route I tried as well watchman watch-del-all and rm -fr /usr/local/var/run/watchman/$USER-state

Solution

You should set a debug server address for a real device.

1. Make sure your laptop and your phone are on the same Wi-Fi network.
2. Open your React Native app on your device.
3. You'll see a red screen with an error. This is OK. The following steps will fix that.
4. Open the in-app Developer menu.
5. Go to Dev Settings → Debug server host for device.
6. Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
7. Go back to the Developer menu and select Reload JS.
