How to set Smart Banner for Android app?

Question

How can I get "smart banner" in spite of simple "banner" in my android app? . I have tried the following code but in vain. It is not showing any banner instead.

    AdView adView = new AdView(this);
    adView.setAdSize(AdSize.SMART_BANNER);
    adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
    mAdView = findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);

Answer 1

The AdView that you are setting Size and UnitID on is not the AdView that you are calling loadAd on. You are setting the ad info on an AdView that you instantiating in code, and then calling loadAd on a view that you are referencing from XML.

mAdView = findViewById(R.id.adView);
mAdView.setAdSize(AdSize.SMART_BANNER);
mAdView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");

AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
