Как показывать межстраничную рекламу при нажатии кнопки «Назад» Android

Хай друзья! Мне нужна помощь от вас, ребята, относительно моего приложения для Android. В основном мой проект Android представляет собой вкладку фрагмента, где я хочу показывать межстраничную рекламу, когда пользователь нажимает кнопку «Назад» перед закрытием приложения.

Пожалуйста, проверьте мой код ниже и помогите мне разобраться с этим вопросом как можно быстрее, спасибо :)

MainActivity.java

public class MainActivity extends AppCompatActivity {



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);



    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);

Загрузите экземпляр объявления в метод onCreate(). Таким образом, вы можете предварительно выбрать объявление без загрузки. И запиши как..

@Override
public void onBackPressed() {
    showAdvertisement();
}

private void showAdvertisement() {
    if (mInterstitialAd.isLoaded()) {
        mInterstitialAd.show();
    } else {
        finish();
    }
}

private void loadInterstitialAd() {
    AdRequest adRequest = new AdRequest.Builder()
            .build();

    mInterstitialAd.loadAd(adRequest);
}

mInterstitialAd = новое межстраничное объявление (это); mInterstitialAd.setAdUnitId(************); mInterstitialAd.setAdListener(new AdListener() { @Override public void onAdClosed() { finish(); } }); загрузить межстраничную рекламу(); - person Meenu Meena; 20.02.2017

Сделайте то же самое в методе onCreate(). Чтобы создать межстраничную рекламу, вам нужно пройти документ Google Admob. - person Meenu Meena; 20.02.2017

Я предполагаю, что вы находитесь в основной активности, и в стеке нет никакой активности. Вам нужно переопределить метод onBackPressed() и добавить код для промежуточного добавления в onBackPressed()

@Override
public void onBackPressed() {
//Interstitial code goes here
}

Для добавления межстраничного кода или справки по коду перейдите по ссылке ниже https://firebase.google.com/docs/admob/android/interstitial
