I am using the following command to generate an iOS build in a CI environment:
react-native run-ios --configuration Release --no-packager
The problem is, this will launch the simulator. I am trying to avoid that as it is a CI machine. Is there a way to generate a build without launching the simulator?

i create one react-native project in expo-cli.
which work correctly in expo go and emulator but when i created eas build of that project i face issue in running build on android device.
My app crash when i tried to run eas build in android device.
My app crash after splash screen.
My app is installed on iphone using eas build --profile development --platform ios and i run the development server expo start --dev-client.
It crashes when i open it. However it's work fine on client Expo go.
How can i debug to solve the problems
After running npx expo run:android once, the app was pushed to the device and the app started up.
I then uninstalled the app on the device and then when I run npx expo run:android once again I get the error:
CommandError: No development build (<package-name>) for this project is installed. Please make and install a development build on the device first.
Learn more: https://docs.expo.dev/development/build/
I started another dummy project with another package name and the same thing can be reproduced after uninstalling once.
The built app is not installing once again on the Android device and then starting up.
The docs referenced in the error states https://docs.expo.dev/development/build/#locally-with-xcode-and-android-studio the following:
If you are comfortable setting up Xcode, Android Studio, and related dependencies, you can build and distribute your app the same as any other iOS or Android app.
The npx expo run commands will create a new build, install it on to your emulator or device, and start running it.
Not sure what I am doing wrong. Any help is appreciated.
Looking at this doc: https://github.com/wix/Detox/blob/master/docs/APIRef.Configuration.md
It says that the
Build command (either xcodebuild, react-native run-ios, etc...), will
be later available through detox CLI tool.
I'm trying to setup the build command to work with Android. Am I supposed to add react-native run-android to the build command? What do they mean by Detox CLI tool?
The build field is optional, and should contain whichever execution logic needed in order to have the .apk file set and ready in the path specified in binaryPath. You are more than welcome to refer to the Detox example project, which was set up as a reference exactly for these type of questions.
In any case, from the react-native CLI tool's help: react-native run-android = builds your app and starts it on a connected Android emulator or device. That makes it not very suitable, as we typically want to build the app, and have detox launch the emulator (optional) and install the app on the device(s), as needed.
I have created one react-native app using expo and atom editor. It's running fine in android device and iOS simulator but with the help of expo. What I want is to generate Apk(debug) so that I can directly run on device. How can I do it ? I followed this(Dmitry Mugtasimov's answer). should I run all those command inside project folder ? Also I don't find index.js file inside my project folder. Also if someone know how to run on iOS simulator by creating app like file(don't know what is that in Ios because from android background). Please help, thanks
Since you have used Expo to develop your react-native app you can build the android app by going to the project folder and running the bellow command in the terminal
expo build:android
The building process will take around 5-10 minutes. When your build is done, expo build:status will give you your .apk file url. If not, it will say your build is still in progress and to try again later.
Also to build the iOS app you can run,
expo build:ios
To build the iOS standalone app you will need to have an Apple Developer account, but for Android standalone app you don't need a Google Play Developer account.
For the above commands to work you need to have expo-cli installed, For this you can run the bellow command,
npm install -g expo-cli
More Info: https://docs.expo.io/versions/latest/distribution/building-standalone-apps/
If you don't have an Apple Developer Account. You can build the iOS
standalone simulator build using the command,
expo build:ios -t simulator
And then wait for build to finish then download and unpack YourAppName.tar.gz. Then, start the iOS simulator and run xcrun simctl install booted YourAppName.app to run the .ica file.
More info: Expo / React-Native, Is it there a way to test-run standalone iOS apps on a device/simulator?
