I was trying to run my app on target device and gradle build was failing because of duplicate classes. I've done the invalidate caches and restart already. :app is currently compiled against android-32.
Recommended action: Update this project to use a newer compileSdkVersion
of at least 33, for example 33.
I was getting this error before and changed the targetSdk and compileSdk from 32 to 33 for both and the rest of the errors followed
Gradle file
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
namespace 'com.example.quizapp'
compileSdk 33
defaultConfig {
applicationId "com.example.quizapp"
minSdk 21
targetSdk 33
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {

}
