This is the error I am facing at the time of building the ios for my expo app.
Here is the code for Image Picker I used
This is working great in my simulator expo app as well as in iphone expo as well but giving this error while building using eas build -p=ios
I try doing different things and after trying many things I get to know it's because of outdated verions I updated everything in my package.json with the help of expo doctor I see compatible and install them and it's fixed.

I am building an app using react-native on Expo and making sure to build with EAS every few days or whenever I add a new dependency.
After every build, I install the apk on an Android device and run the ios build on a simulator.
On my latest build, the build completes successfully but after installing the apk on android 10, the app opens and crashes once I navigate to a certain page.
It works fine on 3 other android phones.
The code difference between the last successful build that doesn't crash to the current one is minimal however very necessary for the app.
How can I see logs from the native crash in order to find the cause of the problem and hopefully find a fix?
I tried to install sentry but at the bottom of the page, it explains it only follows js issues and is not native.
Any ideas will be helpful
Thanks
I was trying execute myapp to android but an error occurred.
To clarify what happened, first time I install nodejs and Android Studio.
Later I used the following commands:
npx react-native init 'app'
cd app
npx react-native run-android
Its my fisrt time messing with react native, I was following this page:
https://learn.microsoft.com/pt-br/windows/dev-environment/javascript/react-native-for-android
And the error is:

I want coding in real time for android app.
How can I fix this?
Looks like the terminal output gives you several steps to do/check.
Make sure you have properly set up your android environment. Use this link to do so. You can use Expo-Cli or React-Native-Cli.
SDK location not found. This could be an off-shoot error of not properly doing step 1. However, to cover all of your bases, ensure you have properly set up your Android Emulator. This doc is a great walkthrough.
Once your Android studio and AVD Manager is properly set up, and your development environment is properly set, you should have no issues!
Please let me know if doing the above to steps did or did not solve your errors.
If you follow the steps, https://reactnative.dev/docs/environment-setup and https://developer.android.com/studio/run/emulator there will be no problem.
As a React Native fan on Windows 10, I'd like to mention just few points you need to check.
First, please check following user variables in Environment Variables ( You can see it from System Properties).
adb="C:\Users{username}\AppData\Local\Android\Sdk\platform-tools"
ANDROID_HOME="C:\Users{username}\AppData\Local\Android\Sdk"
JAVA_HOME="C:\Program Files\OpenJDK\openjdk-11.0.15_10"
Path: check if contains {ANDROID_HOME}\platform-tools
Eg:"C:\Users{username}\AppData\Local\Android\Sdk\platform-tools"
Second, if you are using Android Sdk emulator, please make sure that it configured correctly in emulator list in Android Studio.
For an instance, I created a android emulator using android sdk-29 and you can check the followings.
Third, I recommend you, deploy first app on emulator in Android Studio.
Because we need to download gradle zip file and others, it's essential to run your first android app in Android Studio.
When you confirmed your first android app(Deploy empty project app is also okay), you can run your React Native App by Expo-cli or react-native-cli.
Firstly I created my project with create-react-native-app and I'm developing my app with npm start and I have expo installed on my emulator. How can I convert these project into react native init, I don't want to use expo anymore...I don't neeed any api-es from them...
Thank you
The best resource for this is in the create-react-native-app repository. Try having a look here to get started.
The short answer is to use npm run eject
If you have experience generating signed APKs for Android and code signing with iOS then you shouldn't run into too much trouble.
If you don't, then take the time to go through the Android docs and also this guide should help you get up on running on iOS as well.
Good luck!
Instead of creating your project using the command create-react-native-app, you may create a react native project by following "Building Projects with Native Code" of the getting start guide: https://facebook.github.io/react-native/docs/getting-started.html.
Here you will find out how to:
1. Set up the environment.
2. Installation of phone emulator.
3. Connection of your phone via USB for testing.
4. Create a project using the react-native init command.
I am busy trying to implement camera functionality into an app I am writing in react-native. I have installed react-native-camera via npm and have this working solidly in IOS.
When I try and run on android, the project does not build and throws below error
node_modules/react-native-camera/android/src/main/java/org/reactnative/camera/events/BarCodeReadEvent.java:27: error: no suitable method found for init(int)
I have specified the correct android sdk build tools as described on https://github.com/react-native-community/react-native-camera.
I can run simple projects on my android emulator but as soon as I link the react-native-camera, I am unable to build. Does anyone have any ideas, or experience with this?
I am developing on a mac and as mentioned above. Everything works perfectly on the IOS app.
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.
