This easy-to-follow guide will show you the right way to add these big, full-screen ads without messing up the fun your users are having.

What Are Interstitial Ads?
Interstitial Ads are full-screen ads that cover the entire interface of an Android app. Visually engaging and intriguing, they are typically displayed during natural transition points like the conclusion of a game level or while waiting for a new page load. These ads can effectively capture user attention and, if placed strategically, can highly increase your ad revenue.
Preliminary Steps: Integrating Google Mobile Ads SDK
Before embarking on the journey to add Interstitial Ads in your Android app, you need to integrate the Google Mobile Ads Software Development Kit (SDK) into your application.
Updating your Android Studio
Ensure you have the latest version of Android Studio. It’s essential to have updated tools for seamless integration.
Adding Google Play Services to your Project
Include the Google Play services package into your Project’s build.gradle file. This package is necessary because the Google Mobile Ads SDK is a part of Google Play services.
Adding Interstitial Ads in your Android App
With the prerequisites done, now here’s how you can add Interstitial Ads to your Android App.
Importing the Google Mobile Ads SDK
First, import the Google Mobile Ads SDK in the app-level build.gradle file. Once the Gradle project sync is successful, the SDK is ready to be used.
Adding Interstitial Ads elements
The next step involves creating the Interstitial Ad object, loading it with an ad, and then showing it when needed.

How To Add Interstitial Ads In Your Android App
Below we have provided the source code for every important file that requires change or code addition.
First, you need to update your AndroidManifest.xml file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<!-- The following lines are required for interstitial ads -->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<!-- Make sure you replaced 'com.example.myapp' with your package name -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="YOUR_ADMOB_APP_ID"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Remember to replace "YOUR_ADMOB_APP_ID" with your actual AdMob App ID.
MainActivity.java file to create and load the ad. Here’s a basic example:
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.InterstitialAd;
import com.google.android.gms.ads.MobileAds;
public class MainActivity extends AppCompatActivity {
private InterstitialAd mInterstitialAd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MobileAds.initialize(this,
new OnInitializationCompleteListener() {
@Override
public void onInitializationComplete(InitializationStatus initializationStatus) {
}
});
AdRequest adRequest = new AdRequest.Builder().build();
InterstitialAd.load(this,"YOUR_ADMOB_UNIT_ID", adRequest,
new InterstitialAdLoadCallback() {
@Override
public void onAdLoaded(@NonNull InterstitialAd interstitialAd) {
mInterstitialAd = interstitialAd;
}
@Override
public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
mInterstitialAd = null;
}
});
}
public void mMyButton(View view) {
if (mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
} else {
startActivity(new Intent(this, MainActivity.class));
}
}
}
Activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="14dp"
android:text="Button"
android:onClick="mMyButton"
app:layout_constraintStart_toStartOf="@+id/textView"
app:layout_constraintTop_toBottomOf="@+id/textView" />
</androidx.constraintlayout.widget.ConstraintLayout>
Please adjust the method name in android:onClick to match your method in MainActivity.java. If you don’t have a method called mMyButton in your MainActivity file, you will get a runtime error when clicking the button. So, ensure that a suitable corresponding method exists!
