Gradle: Error: Program type already present: androidx.activity.R$attr

Question

When adding

 implementation 
    ('com.google.android.ads.consent:consent-library:1.0.0') {
        exclude module: 'androidx.activity'
    }

to my app/build.gradle file i get this error: Error: Program type already present: androidx.activity.R$attr

What i did do: 1. gradlew androidDependencies But i cannot find any duplicates

2. Read: https://developer.android.com/studio/build/dependencies#duplicate_classes.

3. Other stackoverflow answers suggesting excluding support library versions dont help me

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

configurations {
    all*.exclude group: 'com.google.guava', module: 'listenablefuture'
}

configurations.all {exclude group: 'com.android.support', module: 'support-v13'}

Please help me understanding where the dependencies have duplicates

Answer 1

I had the same problem. Just using the Clean Project option and building it again worked for me...

Answer 2

It took me two days to fix it but here is the fix:

implementation ('com.google.android.ads.consent:consent-library:1.0.0') {
        exclude group: 'androidx'
    }
