I have been trying to find a solution for the last three days with no luck. I have done following to fix it but its still showing same error
in gradle.properties
android.useAndroidX=true
android.enableJetifier=true
in variables.gradle
minSdkVersion = 23
compileSdkVersion = 30
targetSdkVersion = 26
androidxActivityVersion = '1.2.0'
androidxAppCompatVersion = '1.2.0'
androidxCoordinatorLayoutVersion = '1.1.0'
androidxCoreVersion = '1.3.2'
androidxFragmentVersion = '1.3.0'
junitVersion = '4.13.1'
androidxJunitVersion = '1.1.2'
androidxEspressoCoreVersion = '3.3.0'
cordovaAndroidVersion = '10.1.1'
in build.gradle
repositories {
google()
mavenCentral()
}
...
...
allprojects {
repositories {
google()
mavenCentral()
}
}
None of these changes fixes the issue. However, if I open android build in Android Studio with
ionic cap open android
and add library 'Gradle:androidx.core:core:1.3.0@aar' to class path as intellisense suggestion then it works and and I can run the project on device from Android studio.
But if I make changes and rebuild then it shows same error again.
Please suggest any solution for this.
Many Thanks

try these steps:
ionic cordova plugin add cordova-plugin-androidxionic cordova plugin add cordova-plugin-androidx-adapter
if still not working try step:
npm install jetifier
npx jetifier
npx cap sync android
CodePudding user response：
If u are using Capacitor u cannot "add plugin" as in Cordova...
You have to install it from npm or yarn.
npm i cordova-plugin-androidx npm i cordova-plugin-androidx-adapter....
Or try to update to latest Capacitor, Ionic and Android Studio
