Admob App Open Ads in Android – Admob Ads v-20.2.0

Admob App Open Ads are the latest Ad Formats of Admob. App open ads are a special ad format intended for publishers wishing to monetize their app load screens. App open ads can be closed at any time, and are designed to be shown when your users bring your app to the foreground.

App open ads automatically show a small branding area so users know they’re in your app.

Add these activity lifecycle dependencies in your app-level build.Gradle file.

build.gradle:

//Add these inside dependencies


def lifecycle_version = "2.0.0"
    implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
    implementation "androidx.lifecycle:lifecycle-runtime:$lifecycle_version"
    annotationProcessor "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"

Now First, create a Utility class called AppOpenManager.

AppOpenManager.java

package com.example.admobtutorial;

import android.app.Activity;
import android.app.Application;
import android.os.Bundle;
import android.util.Log;

import androidx.lifecycle.LifecycleObserver;

import androidx.lifecycle.ProcessLifecycleOwner;

import com.google.android.gms.ads.AdError;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.FullScreenContentCallback;
import com.google.android.gms.ads.LoadAdError;
import com.google.android.gms.ads.appopen.AppOpenAd;

import java.util.Date;

import static androidx.lifecycle.Lifecycle.Event.ON_START;

public class AppOpenManager implements LifecycleObserver,Application.ActivityLifecycleCallbacks{

    private static final String LOG_TAG = "AppOpenManager";
    private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/3419835294";
    private AppOpenAd appOpenAd = null;

    private AppOpenAd.AppOpenAdLoadCallback loadCallback;
    private Activity currentActivity;
    private final myApplication myApplication;
    private static boolean isShowingAd = false;
    private long loadTime = 0;

    /** Constructor */
    public AppOpenManager(myApplication myApplication) {
        this.myApplication = myApplication;
        this.myApplication.registerActivityLifecycleCallbacks(this);
        ProcessLifecycleOwner.get().getLifecycle().addObserver(this);
    }

    /** LifecycleObserver methods */
    @OnLifecycleEvent(ON_START)
    public void onStart() {
        showAdIfAvailable();
        Log.d(LOG_TAG, "onStart");
    }

    /** Request an ad */
    public void fetchAd() {
        // We will implement this below.

        // Have unused ad, no need to fetch another.
        if (isAdAvailable()) {
            return;
        }

        loadCallback =
                new AppOpenAd.AppOpenAdLoadCallback() {
                    /**

                     */
                    @Override
                    public void onAdLoaded(AppOpenAd ad) {
                        AppOpenManager.this.appOpenAd = ad;
                        AppOpenManager.this.loadTime = (new Date()).getTime();
                    }

                    /**
                     * Called when an app open ad has failed to load.
                     *
                     * @param loadAdError the error.
                     */
                    @Override
                    public void onAdFailedToLoad(LoadAdError loadAdError) {
                        // Handle the error.
                    }

                };
        AdRequest request = getAdRequest();
        AppOpenAd.load(
                myApplication, AD_UNIT_ID, request,
                AppOpenAd.APP_OPEN_AD_ORIENTATION_PORTRAIT, loadCallback);
    }
    public void showAdIfAvailable() {
// and an ad is available.
    if (!isShowingAd && isAdAvailable()) {
        Log.d(LOG_TAG, "Will show ad.");

        FullScreenContentCallback fullScreenContentCallback =
                new FullScreenContentCallback() {
                    @Override
                    public void onAdDismissedFullScreenContent() {
                        // Set the reference to null so isAdAvailable() returns false.
                        AppOpenManager.this.appOpenAd = null;

                    @Override
                    public void onAdFailedToShowFullScreenContent(AdError adError) {}

                    @Override
                    public void onAdShowedFullScreenContent() {
                        isShowingAd = true;
                    }
                };

        appOpenAd.setFullScreenContentCallback(fullScreenContentCallback);
        appOpenAd.show(currentActivity);

    } else {
        Log.d(LOG_TAG, "Can not show ad.");
        fetchAd();
    }
}

    /** Creates and returns ad request. */
    private AdRequest getAdRequest() {
        return new AdRequest.Builder().build();
    }

    private boolean wasLoadTimeLessThanNHoursAgo(long numHours) {
        long dateDifference = (new Date()).getTime() - this.loadTime;
        long numMilliSecondsPerHour = 3600000;
        return (dateDifference < (numMilliSecondsPerHour * numHours));
    }

    /** Utility method that checks if ad exists and can be shown. */
    public boolean isAdAvailable() {
        return appOpenAd != null && wasLoadTimeLessThanNHoursAgo(4);
    }
    /** ActivityLifecycleCallback methods */
    @Override
    public void onActivityCreated(Activity activity, Bundle savedInstanceState) {}

    @Override
    public void onActivityStarted(Activity activity) {

    }

    @Override
    public void onActivityResumed(Activity activity) {
        currentActivity = activity;
    }

    @Override
    public void onActivityStopped(Activity activity) {}

    @Override
    public void onActivityPaused(Activity activity) {}

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {}

    @Override
    public void onActivityDestroyed(Activity activity) {
        currentActivity = null;
    }


}

Now create an Application class

myApplication.java

package com.example.admobtutorial;

import android.app.Application;

import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

public class myApplication extends Application {

    private static AppOpenManager appOpenManager;

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

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

        appOpenManager = new AppOpenManager(this);

    }
}
