What should replace deprecated Facebook adView setAdListener to get callbacks?

Solution: Since 5.6, you should use loadAd(AdView.AdViewLoadConfig loadAdConfig)

public void loadAd(AdView.AdViewLoadConfig loadAdConfig)

Loads an ad.

This method always returns immediately. The ad is loaded asynchronously. The control's ad listener will be called when loading finishes or fails.

Java

AdView adView = new AdView(this, "placementId", new AdSize(width, height));

AdListener adListener = new AdListener() {
    @Override
    public void onError(Ad ad, AdError adError) {

    }

    @Override
    public void onAdLoaded(Ad ad) {

    }

    @Override
    public void onAdClicked(Ad ad) {

    }

    @Override
    public void onLoggingImpression(Ad ad) {

    }
};

AdView.AdViewLoadConfig loadAdConfig = adView.buildLoadAdConfig()
        .withAdListener(adListener)
        .build();

adView.loadAd(loadAdConfig);

Kotlin

val adView = AdView(this, "placementId", AdSize(width, height))

val adListener = object : AdListener {
    override fun onError(ad: Ad, adError: AdError) {

    }

    override fun onAdLoaded(ad: Ad) {

    }

    override fun onAdClicked(ad: Ad) {

    }

    override fun onLoggingImpression(ad: Ad) {

    }
}

val loadAdConfig = adView.buildLoadAdConfig()
    .withAdListener(adListener)
    .build()

adView.loadAd(loadAdConfig)
