android - play-services-ads conflicts with appcompat

Question

When I add implementation 'com.google.android.gms:play-services-ads:18.2.0' to my build.gradle, Android Studio highlights implementation 'com.android.support:appcompat-v7:28.0.0' with the error:

Dependencies using groupId com.android.support and androidx.* can not be combined but found IdeMavenCoordinates{myGroupId='com.android.support', myArtifactId='versionedparcelable', myVersion='28.0.0', myPacking='aar', myClassifier='null'} and IdeMavenCoordinates{myGroupId='androidx.interpolator', myArtifactId='interpolator', myVersion='1.0.0', myPacking='aar', myClassifier='null'} incompatible dependencies

My build.gradle is:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    configurations.all {
        resolutionStrategy.force 'com.android.support:appcompat-v7:28.0.0'
    }
    defaultConfig {
        applicationId "com.XXXXXX.XXXXXX"
        minSdkVersion 14
        targetSdkVersion 28
        versionCode 3
        versionName "1.1.2"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.google.android.gms:play-services-ads:18.2.0'
    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'
}
