Why am I not getting the V1 and V2 Signature versions checkboxes when i create a APK in Android Studio?

Found it! I have adjusted my gradle file like so:

signingConfigs {
mySigningConfig {
    keyAlias 'theAlias'
    keyPassword 'thePassword'
    storeFile file('theKeystore.jks')
    storePassword 'thePassword'
    v1SigningEnabled true
    v2SigningEnabled true
}

}
