Create Admob App Loading Ad on Android

Tiempo de lectura: 2 minutos

Today we are going to learn how to create an app loading ad with Admob on Android.

First, we will implement in our build.gradle:

    implementation 'com.google.android.gms:play-services-ads:23.0.0'

Then we need to initialize the ads in our MainActivity:

    MobileAds.initialize(
        this,
        new OnInitializationCompleteListener() {
          @Override
          public void onInitializationComplete(InitializationStatus initializationStatus) {}
        });

And add in the manifest (below </application>)

    <meta-data
        android:name="com.google.android.gms.ads.AD_MANAGER_APP"
        android:value="true" />

And also inside <application> </application>

        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="YOUR_ADMOB_APP_ID" />

Replace YOUR_ADMOB_APP_ID with your Admob APP id.

Now let’s create an object called AppOpenManager.java where we will put this code:

<

public AppOpenAdManager() {

    return appOpenAd != null && wasLoadTimeLessThanNHoursAgo(4);
}

/**

public void showAdIfAvailable(@NonNull final Activity activity,
                              @NonNull MyApplication.OnShowAdCompleteListener onShowAdCompleteListener) {
    if (isShowingAd) {
        Log.d(LOG_TAG, "The app open ad is already showing.");
        return;
    }
    // If the app open ad is not available yet, invoke the callback then load the ad.
    if (!isAdAvailable()) {
        Log.d(LOG_TAG, "The app open ad is not ready yet.");
        onShowAdCompleteListener.onShowAdComplete();
        loadAd(activity);
        return;
    }
    appOpenAd.setFullScreenContentCallback(
            new FullScreenContentCallback() {

                    isShowingAd = false;
                    onShowAdCompleteListener.onShowAdComplete();
                    loadAd(activity);
                }

                @Override
                public void onAdFailedToShowFullScreenContent(AdError adError) {
                    // Called when fullscreen content failed to show.

    isShowingAd = true;
    appOpenAd.show(activity);
}

public void loadAd(Context context) {
    // Do not load ad if there is an unused ad or one is already loading.
    if (isLoadingAd  isAdAvailable()) {
        return;
    }

    isLoadingAd = true;
    AdRequest request = new AdRequest.Builder().build();
