Встраивать рекламу в код, отображается только пустое поле

Question

Многие ошибки не отображаются и реклама не отображается в fragment_home.xml

Есть код баннера, как сделать баннер в этом коде?

Мой home_fragment.xml

   <TextView

   </LinearLayout>

Answer 1

Просто добавить его к xml недостаточно. Вам необходимо загрузить его в коде.

MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });
        mAdView = findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
