AAPT: error: resource android: attr/IStar not found.

This error occurred suddenly, it was working fine last week.

enter image description here

I've tried many solutions but none works. Solutions tried:

  1. Delete, reinstall npm, using npm install
  2. clean gradle with ./gradlew clean in /android
  3. Cleaning npm cache with npm cache clean --force
  4. add org.gradle.jvmargs=-Xmx4608m in /android/gradle.properties
  5. In /android/build.gradle, inside ext{} add androidXCore = "1.6.0"
  6. npm update @react-native-community/netinfo
  7. androidx.core:core-ktx:+ to androidx.core:core-ktx:1.6.0 but I've searched through my project, there is no 'androidx.core:core-ktx:+. So this solution I found is irrelevant.

Version:

"react-native": "0.63.4",

compileSdkVersion = 29
targetSdkVersion = 29

Add this in your android/buld.gradle file.

def REACT_NATIVE_VERSION = new File(['node', '--print',"JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim())

allprojects {
    configurations.all {
        resolutionStrategy {
            // Remove this override in 0.65+, as a proper fix is included in react-native itself.
            force "com.facebook.react:react-native:" + REACT_NATIVE_VERSION
        }
    }

There had been a series of build failures React Native & Expo users have been experiencing when building Android apps starting from November 4th 2022. Your issue is the same.

Since you are using React-native 0.63 React-native has a new patch released for it. try updating your react-native in your package.json from "react-native": "^0.63.4" to "react-native": "^0.63.5" and try running npm install and everything will work fine.

The suggested answer by Thanhal will give you some headaches if you try to upgrade to a new version of react-native and forget to remove it from build.gradle.

for more info please refer to This issue on github

Ahh, thanks for your information and github link, will take note on that and will change later.
@AhChing11 have you got the time to try my suggestion?
So sorry I was rushing on deadlines, I'll try it next week.
I've tried upgrading to 0.63.5. But it returns 2 errors 1. > A problem occurred evaluating script. > Cannot run Project.afterEvaluate(Closure) when the project is already evaluated. 2. A problem occurred configuring project ':app'. > compileSdkVersion is not specified. Please add it to build.gradle
Have you undo the changes on android/build.gradle before upgrading
