ADMOB Ads with Multi WebView App with Fragment Layout in Android Studio | Complete Tutorials

First, we must implement dependency and add some code in the Manifest. file in our project.

NOTE: Requirment “minSDK” – 19 and we have give acess “INTERNET“permission.

<uses-permission android:name="android.permission.INTERNET" />

// Admob Ads Dependency
implementation 'com.google.android.gms:play-services-ads:21.1.0'

<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-3940256099942544~3347511713"/>

Second, we can create topic-wise details:

• Banner Ads Format.
• Smart Banner Ads Format.
• Medium Rectangle Banner Ads Format.
• Interstitial Ads Format.
• App Open Ads Format.

• Implement Banner Ads Format.

First, we have to create and implement an XML code in the Activity layout given below.

<FrameLayout
    android:id="@+id/fragmentContainer"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:layout_constraintBottom_toTopOf="@+id/adView"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    app:adSize="BANNER"
    app:adUnitId="ca-app-pub-3940256099942544/6300978111"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintVertical_bias="1" />

Second, we have to create and implement a JAVA code in the Activity class given below.

// AdView Variable
private AdView mAdView;

 // Admob Ads Code Here

        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });
        mAdView = findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);

• Implement Smart Banner Ads Format.

Here, we can XML layout only and all JAVA code are the same even do nat try to change any code in the JAVA file for this Ads format.

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    app:adSize="SMART_BANNER"
    app:adUnitId="ca-app-pub-3940256099942544/6300978111"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintVertical_bias="1" />

• Implement Medium Rectangle Banner Ads Format.

Here, we can XML layout only and all JAVA code are the same even do nat try to change any code in the JAVA file for this Ads format.

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    app:adSize="MEDIUM_RECTANGLE"
    app:adUnitId="ca-app-pub-3940256099942544/6300978111"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintVertical_bias="1" />

• Implement Interstitial Ads Format.

In this ad format, we have to create JAVA code only. And follow step by step.

Insert the below code under the onCreate method.

// Interstitial Ad
loadInterstitialAd();

Now, we can create a code under AppCompatActivity.

public void loadInterstitialAd() {
    AdRequest adRequest = new AdRequest.Builder().build();
    InterstitialAd.load(this, "ca-app-pub-3940256099942544/1033173712", adRequest,
            new InterstitialAdLoadCallback() {
                @Override
                public void onAdLoaded(@NonNull InterstitialAd interstitialAd) {

                    Toast.makeText(HomeActivity.this, "Ad Loaded", Toast.LENGTH_SHORT).show();
                    interstitialAd.show(HomeActivity.this);
                    interstitialAd.setFullScreenContentCallback(new FullScreenContentCallback() {
                        @Override
                        public void onAdFailedToShowFullScreenContent(@NonNull AdError adError) {
                            super.onAdFailedToShowFullScreenContent(adError);
                            Toast.makeText(HomeActivity.this, "Faild to show Ad", Toast.LENGTH_SHORT).show();
                        }

                        @Override
                        public void onAdShowedFullScreenContent() {
                            super.onAdShowedFullScreenContent();
                            Toast.makeText(HomeActivity.this, "Ad Shown Successfully", Toast.LENGTH_SHORT).show();
                        }

                        @Override
                        public void onAdDismissedFullScreenContent() {
                            super.onAdDismissedFullScreenContent();
                            Toast.makeText(HomeActivity.this, "Ad Dismissed / Closed", Toast.LENGTH_SHORT).show();
                        }

                        @Override
                        public void onAdImpression() {
                            super.onAdImpression();
                            Toast.makeText(HomeActivity.this, "Ad Impression Count", Toast.LENGTH_SHORT).show();
                        }

                        @Override
                        public void onAdClicked() {
                            super.onAdClicked();
                            Toast.makeText(HomeActivity.this, "Ad Clicked", Toast.LENGTH_SHORT).show();
                        }
                    });
                }

                @Override
                public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
                    Toast.makeText(HomeActivity.this, "Failed to Load Ad because=" + loadAdError.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });
}

Now, we have to create three methods to “onPause”, “onResume” and “onDestroy” under AppCompactActivity.

@Override
public void onPause() {
    if (mAdView != null) {
        mAdView.pause();
    }
    super.onPause();
}

@Override
public void onResume() {
    super.onResume();
    if (mAdView != null) {
        mAdView.resume();
    }
}

@Override
public void onDestroy() {
    if (mAdView != null) {
        mAdView.destroy();
    }
    super.onDestroy();
}

• Implement App Open Ads Format.

If you really want to create App Open Ads then you must set the fixed dependency given below.

// Admob Ads Dependency
implementation 'com.google.android.gms:play-services-ads:19.6.0'

Now, you can be implemented the above dependency then you have to move coding in java files. So First we have to create a JAVA file named “MyApplication” then you have to insert the below code in your project.

public class MyApplication extends Application {

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

        MobileAds.initialize(this, initializationStatus -> {
        });
        AppOpenManager appOpenManager = new AppOpenManager(this);
    }
}

After that, we have to create one more JAVA file named “AppOpenManager” then you can insert all java code into your project.

public class AppOpenManager implements Application.ActivityLifecycleCallbacks {

    private Activity currentActivity;
    private static boolean isShowingAd = false;
    private static final String LOG_TAG = "AppOpenManager";
    private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/3419835294";
    private AppOpenAd appOpenAd = null;
    private long loadTime = 0;
    private final MyApplication myApplication;

    // Constructor
    public AppOpenManager(MyApplication myApplication) {
        this.myApplication = myApplication;
        this.myApplication.registerActivityLifecycleCallbacks(this);
    }

    // Request an Ads
    public void fetchAd() {
        if (isAdAvailable()) {
            return;
        }

        AppOpenAd.AppOpenAdLoadCallback loadCallback = new AppOpenAd.AppOpenAdLoadCallback() {
            @Override
            public void onAppOpenAdLoaded(AppOpenAd ad) {
                AppOpenManager.this.appOpenAd = ad;
                AppOpenManager.this.loadTime = (new Date()).getTime();
            }

            @Override
            public void onAppOpenAdFailedToLoad(LoadAdError loadAdError) {

            }

        };
        AdRequest request = getAdRequest();
        AppOpenAd.load(
                myApplication, AD_UNIT_ID, request,
                AppOpenAd.APP_OPEN_AD_ORIENTATION_PORTRAIT, loadCallback);

    }

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

    // Utility method to check if ad was loaded more than n hours ago.
    private boolean wasLoadTimeLessThanNHoursAgo() {
        long dateDifference = (new Date()).getTime() - this.loadTime;
        long numMilliSecondsPerHour = 3600000;
        return (dateDifference < (numMilliSecondsPerHour * (long) 4));
    }

    // Check if ad exists and can be shown
    public boolean isAdAvailable() {
        return appOpenAd != null && wasLoadTimeLessThanNHoursAgo();
    }

    @Override
    public void onActivityCreated(@NonNull Activity activity, @Nullable Bundle savedInstanceState) {

    }

    @Override
    public void onActivityStarted(@NonNull Activity activity) {
        currentActivity = activity;
        showAdIfAvailable();

    }

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

    @Override
    public void onActivityPaused(@NonNull Activity activity) {

    }

    @Override
    public void onActivityStopped(@NonNull Activity activity) {

    }

    @Override
    public void onActivitySaveInstanceState(@NonNull Activity activity, @NonNull Bundle outState) {

    }

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

    }

    // Shows the ad if one isn't already showing.
    public void showAdIfAvailable() {
        if (!isShowingAd && isAdAvailable()) {
            Log.d(LOG_TAG, "Will show ad.");

            FullScreenContentCallback fullScreenContentCallback =
                    new FullScreenContentCallback() {
                        @Override
                        public void onAdDismissedFullScreenContent() {
                            AppOpenManager.this.appOpenAd = null;
                            isShowingAd = false;
                            fetchAd();
                        }

                        @Override
                        public void onAdFailedToShowFullScreenContent(AdError adError) {
                        }

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

            appOpenAd.show(currentActivity, fullScreenContentCallback);

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