Просьба проверить мой кодирования ниже, и помочь мне разобраться в этом вопрос, как быстро, как вы можете спасибо :)

Я предполагаю, что вы стоите на основной деятельности и не существует какая-либо активность в stack.You необходимо переопределить onBackPressed() метод и добавить код для interstetial добавить в onBackPressed()

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

Для добавления промежуточного кода или обратитесь к коду ниже ссылки https://firebase.google.com/docs/admob/android/interstitial

Загрузите объявление Экземпляр в метод onCreate(). Итак, вы можете предварительно выбрать объявление без загрузки. И записать это 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); 
} 
+0

где добавить код интерстициального объявления –

+0

mInterstitialAd = новый InterstitialAd (это); mInterstitialAd.setAdUnitId ("************"); mInterstitialAd.setAdListener (новый AdListener() { @Override общественные недействительный onAdClosed() { отделки();} }); loadInterstitialAd(); –

+0

Сделайте это в методе onCreate(). Чтобы создать interstitialAd, вам нужно пройти через документ Google Admob. –
