I had been working with react native for few days and I used to run my app in my own android phone through LAN. But recently the expo client app is not supporting. When I open it it shows all the recent project as well as working project. when I click on working once it shows all the normal stuffs like Dowloading javascript bundles and in metro bundler also it shows Building JavaScript bundle: finished in 5380ms. No problem there. But when it finishes a pop up came and show Expo stopped
like this :
I cleared the cashe and atlast reinstalled expo client app in android device and expo-cli in my system. Still the problem persisting. How to resolve it... :(

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.
My React native app working fine two days ago but when I installed new library and did pod install then app is not running and showing error "RnAlarmNotification.h file not found" in ios app on xcode.
I tried to run application for implementing Stripe 3ds but app is not running. now I need to solve "RnAlarmNotification.h" file not found issue to further development.
Screen shot the error what issue I am facing.
I've been working on a react-native app managed mode built on expo, I was working from a mac at first which worked perfectly fine using the IOS simulator it didn't work on android emulator on mac, here i switched to a windows computer and the issue still exists on the android emulator, executing the command "expo start" the app crashes after the splash screen before the logo appears, I tested the app on a real device on the debug mode and it worked! also after deploying the apk file the app works with no issues, the only problem is it's not working on android simulator using expo client, things i tried to solve the issue including trying to reinstall android studio and install the latest version, tried updating expo sdk to latest version also tried playing around with the app.js from where the app launches the first time but still crashes at the same point, it's not showing any errors or warning it just crashes, any suggestion or something i could try would be very helpful thanks.
I am also having a similar issue : after upgrading to the latest release (SDK 41) the android simulator hangs often and the app crash without any errors. But works some time .
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 have been working with React native for a few days now. Everything seemed to be working fine until I installed Nativebase. Now either I would get this error:
OR it would get stuck at around 97% while Building JavaScript bundle after a couple of Project restarts and clearing cache. This happens regardless of whether I'm running on my phone or the emulator. I'm using the Expo XDE but its the same with the cmd.
