问题

I am new to this. I have been trying to connect an app to Admob. When I attempt to connect, it always triggers the onAdFailedToLoad() method. This is the same for banner, interstitial and rewarded ads. Please what am I doing wrong?

In the MainActivity, I have:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    MobileAds.initialize(MainActivity.this, "ca-app-pub-XXXXXXXXXXXXXXXX~XXXXXXXXXX");

    //   --- Admob ---
    view = getWindow().getDecorView().getRootView();

    Admob.createLoadBanner(getApplicationContext(), view);
    Admob.loadBanner();
    //   --- *** ---

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

In the Admob class, I have:

public static void createLoadBanner(final Context context, View view) {
    mAdView = view.findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().
            addTestDevice("ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX").
            build();
    mAdView.loadAd(adRequest);
    mAdView.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            Toast.makeText(context, "Banner Ad has been loaded.", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onAdClosed() {
            super.onAdClosed();
            Toast.makeText(context, "Banner Ad has been closed.", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onAdOpened() {
            super.onAdOpened();
            Toast.makeText(context, "Banner Ad has been opened.", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onAdLeftApplication() {
            super.onAdLeftApplication();
            Toast.makeText(context, "Banner Ad is being redirected.", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onAdFailedToLoad(int errorCode) {
            super.onAdFailedToLoad(errorCode);
            Toast.makeText(context, "Banner Ad failed to load!", Toast.LENGTH_LONG).show();
            // loadBanner();
        }
    });
}

public static void loadBanner() {
    if (!mAdView.isLoading()) mAdView.loadAd(new AdRequest.Builder().
            addTestDevice("ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX").
            build());
}

@Override
public void onCreate(BundleInstanceState bundle) {
super.onCreate(bundle);
MobileAds.initialize(MainActivity.this, "ca-app-pub-XXXXXXXXXXXXXXXX~XXXXXXXXXX");
//   --- Admob ---
view = getWindow().getDecorView().getRootView();
Admob.createLoadBanner(getApplicationContext(), view);
Admob.loadBanner();
//   --- *** ---
adView = findViewById(R.id.adView);
adView.loadAd(new AdRequest.Builder().build());
}

public static void createLoadBanner(final Context context, View view) {
mAdView = view.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().
addTestDevice("ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX").//ca-app-pub-3940256099942544/6300978111
build();
mAdView.loadAd(adRequest);
mAdView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
super.onAdLoaded();
Toast.makeText(context, "Banner Ad has been loaded.", Toast.LENGTH_LONG).show();
}
@Override
public void onAdClosed() {
super.onAdClosed();
Toast.makeText(context, "Banner Ad has been closed.", Toast.LENGTH_LONG).show();
}
@Override
public void onAdOpened() {
super.onAdOpened();
Toast.makeText(context, "Banner Ad has been opened.", Toast.LENGTH_LONG).show();
}
@Override
public void onAdLeftApplication() {
super.onAdLeftApplication();
Toast.makeText(context, "Banner Ad is being redirected.", Toast.LENGTH_LONG).show();
}
@Override
public void onAdFailedToLoad(int errorCode) {
super.onAdFailedToLoad(errorCode);
Toast.makeText(context, "Banner Ad failed to load!", Toast.LENGTH_LONG).show();
// loadBanner();
}
});
}
public static void loadBanner() {
if (!mAdView.isLoading()) mAdView.loadAd(new AdRequest.Builder().
addTestDevice("ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX").//ca-app-pub-3940256099942544/1033173712
build());
}
