Edit: problème résolu il suffit d'ajouter les @Afterviews d'appel comme celui-ci

@AfterViews 
void afterViews() { 
    if (uri != null) { 
     displayFromUri(uri); 
    } else { 
     displayFromAsset(SAMPLE_FILE); 
    } 
    setTitle(pdfFileName); 

    MobileAds.initialize(getApplicationContext(), "app-id"); 

    AdView mAdView = (AdView) findViewById(R.id.adView); 
    AdRequest adRequest = new AdRequest.Builder().build(); 
    mAdView.loadAd(adRequest); 
} 

PS Je suis nouveau à la programmation.

Answer 1

Tout d'abord, je vous recommande de jeter un oeil à la documentation Activity Lifecycle. S'il n'y a pas de méthode onCreate() dans le code que vous avez fourni, vous devrez ajouter la méthode vous-même. L'éthique de pourquoi vous modifier un produit sous licence Apache 2.0 pour insérer uniquement annonces de côté, dans votre cas, il serait

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    Super.onCreate(savedInstanceState); 
    MobileAds.initialize(getApplicationContext(), "app-id"); 

    AdView mAdView = (AdView) findViewById(R.id.adView); 
    AdRequest adRequest = new AdRequest.Builder().build(); 
    mAdView.loadAd(adRequest); 
} 

Notez également que le code fourni dans cette activité fait un usage intensif de Android Annotations, je Je vous conseille de passer un peu de temps à vous familiariser avec un peu plus de code vanilla avant de passer aux librairies qui vous font gagner du temps.

Answer 2

Problème résolu, il suffit de mettre en @Afterviews comme ceci:

@AfterViews 
void afterViews() { 
if (uri != null) { 
    displayFromUri(uri); 
} else { 
    displayFromAsset(SAMPLE_FILE); 
} 
setTitle(pdfFileName); 

MobileAds.initialize(getApplicationContext(), "app-id"); 

AdView mAdView = (AdView) findViewById(R.id.adView); 
AdRequest adRequest = new AdRequest.Builder().build(); 
mAdView.loadAd(adRequest); 
}
