Using Kotlin & RxJava Observers

Import in your Gradle file

implementation 'com.google.android.gms:play-services-ads:15.0.0'

Import on top of your kotlin source file

import io.reactivex.Observable
import com.google.android.gms.ads.identifier.AdvertisingIdClient

Implement a helper function

    private fun fetchAdIdAndThen(onNext : Consumer, onError : Consumer) {
        Observable.fromCallable(Callable {
            AdvertisingIdClient.getAdvertisingIdInfo(context).getId()
        }).subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(onNext, onError);
    }

Then

    fetchAdIdAndThen(Consumer() {
        adId ->
        performMyTaskWithADID(activity, 10000, adId);
    }, Consumer() {
        throwable ->
        throwable.printStackTrace();
        performMyTaskWithADID(activity, 10000, "NoADID");
    })
