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

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

Please help me understanding where the dependencies have duplicates

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

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'
}

Android build issue

I get error "Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 16.0.5."

I saw errors downloading FireBase libraries as well while gradle performs synchronization. I'm upgrading an old app in order to use geofencing API.
Many thanks.

Update the classpath 'com.google.gms:google-services:4.1.0' in project build.gradle.

I am using two plugin annotationProcessor one for Room database and other for Glide Plugin but as soon as i add annotationProcessor for Room Database. It seem GLide annotationProcessor is getting override and I am getting compilation error for Glide Plugin in my project. How to run both in my project ?

Make sure your root gradle look like this:
allprojects {
repositories {
jcenter()
google()
}

Program type already present: com.android.volley.Cache$Entry

When I run my Application it returns this error By searching ,I realised that I have to change dependency in the gradle file but I don't know what to change . This is my build.gradle file :
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})

implementation 'com.android.support:support-v4:27.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.github.sundeepk:compact-calendar-view:1.9.1'
implementation 'com.mcxiaoke.volley:library-aar:1.0.0'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.google.android.gms:play-services-location:10.2.4'
implementation 'com.android.support.constraint:constraint-layout:1.0.0-beta1'
implementation 'com.android.volley:volley:1.0.0'
implementation 'com.jakewharton:butterknife:8.5.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'
}

FYI
implementation 'com.mcxiaoke.volley:library-aar:1.0.0' is DEPRECATED
Remove dependencies of implementation 'com.mcxiaoke.volley:library-aar:1.0.0' from your Build.Gradle
Than Clean-Re-Build-Run your project
EDIT
Latest version is compile 'com.android.volley:volley:1.1.1'

Just exclude volley like below I did and it will work
implementation ('com.google.android.libraries.places:places:2.1.0'){
exclude group: 'com.android.volley'
}

I also got same problem after long research fortunately i find solution and here it's
configurations {
all*.exclude group: 'com.squareup.okio'
all*.exclude group: 'com.squareup.okhttp3'
all*.exclude group: 'com.android.support', module : 'support-v13'
}
Just put this code in app folder build.gradle file, it's look like
configurations {
all*.exclude group: 'com.squareup.okio'
all*.exclude group: 'com.squareup.okhttp3'
all*.exclude group: 'com.android.support', module : 'support-v13'
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'

}

Paytabs SDK is using okhttp jar file, you can exclude okhttp by configuration
android {
configurations {
all*.exclude group: 'com.squareup.okhttp3', module: 'okhttp'
}
}
