[@Habitual-Developer]

[@user-dm2kl7dw2h]

if it is crush after lounch then remove node modules and package-lock install packages using yarn and then during build check errors and in my case it was about add package react-native-screens

Build failed: Gradle build failed with unknown error. See logs for the "Run gradlew" phase for more information. how to resolve this problem?

[@my_extreme_code]

When encountering a Gradle build failure with an unknown error, it can be challenging to pinpoint the exact cause without additional information or error logs. However, here are some general troubleshooting steps you can follow to resolve the issue: Check the error logs: Look for the specific error message or stack trace provided in the logs for the "Run gradlew" phase. The logs can usually be found in the console output or in a separate log file. Understanding the specific error message can help you identify the root cause of the problem. Verify Gradle version: Ensure that you are using a compatible Gradle version for your project. Check the Gradle documentation or the project's documentation to determine the recommended Gradle version. You can also try updating Gradle to a newer version if you are using an outdated one. Check for dependency conflicts: Gradle builds can fail due to conflicts between different dependencies. Use the dependency management features of Gradle to analyze and resolve any conflicts. You can try excluding or updating specific dependencies to resolve conflicts. Clean and rebuild: Sometimes, build failures can be caused by corrupt or outdated build artifacts. Try cleaning the project build by running gradlew clean or ./gradlew clean (depending on your operating system) before attempting to rebuild. This will remove any previously generated build files and start with a clean slate. Internet connectivity: Gradle relies on internet connectivity to download dependencies and plugins. Ensure that you have a stable internet connection and that any necessary proxies or firewalls are properly configured. Check for build script errors: Review your Gradle build scripts (build.gradle or build.gradle.kts) for any syntax errors or misconfigurations. Pay attention to the tasks, dependencies, and plugins specified in the build scripts. Gradle wrapper: If you are using the Gradle wrapper (gradlew or gradlew.bat), make sure it is properly configured and up to date. You can try updating the Gradle wrapper by running gradlew wrapper --gradle-version X.Y.Z (replace X.Y.Z with the desired Gradle version). Seek help: If you have tried the above steps and the issue persists, consider seeking help from the Gradle community or the specific project's support channels. They may be able to provide more targeted guidance based on the error logs or project-specific configuration. Remember to provide as much relevant information as possible when seeking assistance, such as the error message, relevant portions of the build script, and any additional context that might be helpful in diagnosing the problem.

Better English than some guys, Beto ... congrats 😀👍 By the way, can you explain how to run and configure that Emulator on the right side on the screen, man. Thanks in advance 😀👍

[@codewithbeto]

Thanks bro! Do you mean the IOS simulator? You just need to download Xcode 👍👍

[@sp-ef2fi]

So in Windows using EAS we can only target android simulator but not iOS? Then what is the benefit of using Expo over react native cli?

[@codewithbeto]

Yes you can target android, this tutorial is just for android

[@anillimbu7092]

When i run this command in my terminal eas build:configure it says zsh: command not found: eas, how to fix it ?

[@codewithbeto]

You need to install the expo CLI, refer to the expo documentation for instructions 👍

So, how do you pass the point with the node version problem? It seems like there's nothing I can do. It's literally the first problem, yet I can't seem to find a solution. How did you solve this?

[@codewithbeto]

Can you provide more context to this problem? I’m not sure what error you are referring

[@michaellevi1474]

@@codewithbeto Sure. Expo doesn't support the LSV of Node, but not even the latest version, but the last 3 versions. I believe Node v16 and below are supported by Expo. Has something to do with Node using different hashing for security, I dunno. So my question is, is there a way around it? Or is the only way to downgrade node to version that supports Expo?

[@codewithbeto]

It should work with node 18 but you can try using a node version manager like nvm to quickly change between node versions in your computer. I hope this helps

[@ItsMe-fj1co]

ver helpful, tu ver much!

[@patriciodiaz4483]

Hi! I have a question, how you configure the environment variables for development and production? I read the documentation and it says you have to pass them in thw eas.json file, but when I do it and build my preview android apk, it doesn't works

[@sfallpeoplefaiz4473]

show me ur eas.json code

[@wendigo6372]

Did you solve it?

[@patriciodiaz4483]

@@wendigo6372 yes I figured it out, I was able to set 3 environments, in my case development, preview and production. Also I found a way to change the App name depending of this one

[@patriciodiaz4483]

{ "cli": { "version": ">= 6.0.0" }, "build": { "development": { "developmentClient": true, "distribution": "internal", "env": { "EXPO_PUBLIC_API_EXAMPLE": "", "EXPO_PUBLIC_API_EXAMPLE_2": "" }, "android": { "buildType": "apk" } }, "preview": { "distribution": "internal", "android": { "buildType": "apk" }, "env": { "EXPO_PUBLIC_API_EXAMPLE": "", "EXPO_PUBLIC_API_EXAMPLE_2": "", "APP_VARIANT": "preview" } }, "production": { "env": { "EXPO_PUBLIC_API_EXAMPLE": "", "EXPO_PUBLIC_API_NODO_EXAMPLE_2": "" }, "android": { "buildType": "apk" } } }, "submit": { "production": {} } }

[@patriciodiaz4483]

That is the structure I use for eas.json. The important thing to set the correct prefix variable in env object, is a must to type the EXPO_PUBLIC_API_ . Another thing is the APP_VARIANT, is optional, but this will help you as a environment variable to be able to change some dynamic values (in my case de name of the app), I will comment an example

[@Lobos91]

There is 30 free builds a month in free plan, does it mean i can only run my app 30 times in visual code? That would be insane if there is 5 people working on app amd we daily open amd run it like 50 times

[@awaisDeshmukh]

As I understand it, it is not about running the app in Visual Studio Code, but rather about building it, which means that one can build the Android app up to 30 times and the iOS app up to 15 times. Trust me, I've run my own expo app more than 500 times in a month with Visual Studio Code. In other words, it's not about running an app, but about building an apk. I hope my response was helpful.

My app works via Metro but it crashes after splash screen when I try to launch it via apk. 😭

[@arpanbajpai1226]

Is your problem resolved?plz help me.

[@EdikTVSet]

@arpanbajpai1226 yep yep. I figured it out via creating a new project. In the new project I realized that I made some mistakes in previous project. For example, my way of installing packages was wrong. I used to installing packages using "npm install" but the right way is "npx expo install nameOfPackageYouWannaInstall" It was the main problem. Also, there were other problems with layout. I had some red errors but it worked via Metro. But unfortunately it doesn't work via apk. Make sure your project doesn't have errors.

@arpanbajpai1226 try to create a new empty project. Then build it. Does it work? If so, great. Start adding new content step-by-step, build and test project. This way you will find the problem cuz one time you will get a wrong build. And you will know the reason why
