Windows 7 64bits
Genymotion
I just upgraded my code to react native 0.30, 0.31, 0.32. Live and hot reload not working anymore. It works perfect in 0.28.
I tried on clean project also not working and no error in cmd and js debugger.
Here is the progress
react-native init Project
cd Project
react-native run-android
then in Genymotion
Enable Live Reload
Enable Hot Loader
The app is refreshed when file saved but nothing changed.
The only way to make the app reload is react-native run-android again.
Any idea?

After opening my React Native project in Expo, I get a "New update available, downloading..." infinite loading on the Android emulator.
I tried restarting the server and restarting the emulator, expecting to see the actual content of my React Native application.
I managed to solve this problem by following these steps:
Stop the server.
Uninstall Expo on Android emulator.
Run npm start.
Reopen the application on Android emulator.
I am creating a simple app. It was working smoothly in emulator but after running on real physical android device it is not working on both emulator and device.
I am using react-native-cli.
After running
npm start android
I am getting below screen.
And in device it showing loading please check the below image. I patiently waited but still no luck its on the same loading screen.
Have you tried to run it on Android Studio itself after this command:
npx react-native start --reset-cache
Restart your phone.
That's all I had to do and the issue fixed itself.
I want to run my React Native app in the iOS emulator. Here is what I done so far:
I installed XCode, along with its command line tools, and can bring up the emulator without issue.
I created an empty React Native app using the Expo CLI, per the instructions here. https://facebook.github.io/react-native/docs/getting-started. I am running on Node v10.0.0 on a Mac.
Afterwards I install all the necessary dependencies.
I then run "sudo npm run ios". This fires up the Metro Bundler as well as the iOS simulator. The Simulator loads up after about 5 minutes of waiting, but my app does not start up.
What am I missing here?
I should note that I prefer to stick with Expo, so I'd prefer not to have to eject.
I'm trying to run a boilerplate react-native app and the packager seems to stall out right at the beginning when the javascript bundle is requested. Eventually the iOS simulator gives up and throws Could not connect to development server.
Here is the terminal output:
[01/17/2017, 10:48:00] <START> Initializing Packager
[01/17/2017, 10:48:00] HMR Server listening on /hot
React packager ready.
[01/17/2017, 10:48:47] <START> Requesting bundle
bundle_url: /index.ios.bundle?platform=ios&dev=true&minify=false
I haven't been in react-native for a few months but I used to be able to specify whether the app should load from a bundle or just load the js directly. I would load directly when the xCode project was in debug mode or from a bundle when in release mode.
Again this is just straight boilderplate - no external packages or anything. Just using react-native init TestProj and then cd TestProj/ && react-native run-ios
I'm using the last version of react-native 0.40.0 and the expected react dependency of react#~15.4.0-rc.4.
Thanks for any help on this.
I'm not sure what the issue was but it was fixed after I restarted my computer. I also had issues getting the code to refresh once the app was loaded. That was fixed by uninstalling nodemon globally.
I have a problem when running react-native run-ios on my project.
The IOS emulator launch well.
Then the application start (react-native white splash screen) and immediately after that, it return me to the Iphone home screen.
If I Cmd-Shift-H (with pressing H two times) I saw the app in the background (still with the react-native white splash screen).
When I click on it, it return me to the home screen again.
If I launch the Xcode project and run the app, it work fine and I can navigate in my application.
I've had some troubles with my app before, the IOS version was 'abandoned' and I've installed a lot of modules and changed the name of the project in the mean time, before trying to make it work on IOS.
Then I've decided to create a new project with react-native init myNewProject (because I couldn't figured out how to fix the IOS, something with a workspace not configured) and copy paste my old src and index.ios/android.js inside.
So now Android is still working and IOS is only working if I launch the app from Xcode.
I've tried to reset the emulator but it don't change anything.
I don't have any logs about app crash or something.
The Android app version is working fine.
Any idea ?
Logs
I've put the device logs after running react-native run-ios on a gist

Additional Information
React Native version: 0.35
Platform: IOS
Operating System: macOS El capitan
Xcode: Version 8.0
I ran into this problem, and solve it:
In my case i install third-party native component in my project and link it using command react-native link <component-name>. Than i have a problem about you wrote:
Running project by Xcode - works fine. Bundling start, after loading dependency graph.
But runnig project by react-native run-ios app hide immediately and bundling not started after loading dependency graph. And not any errors happened.
I tried reinstall all, clean npm cache, react-native upgrade, delete build folder, delete derived data... nothing helped.
I found one way that helped me:
I remove that problem library not manyally from Xcode, but from terminal using command react-native unlink <component-name>. Its way to resolve this problem for me, maybe for you too.
Sorry for my english.
