1.  Banner Ad
2.  Native Ad
3.  Rewarded Ad
4.  Interstitial Ad

Now, let’s get started with how to place a code of Interstitial Ad in your Android Application. I have assumed that you are using Android Studio for developing your app and your project is opened in it. Follow the below steps and copy paste the code into your project carefully.

⟩⟩  First of all, you need to add below line of code in your build.gradle dependencies file.

compile 'com.google.android.gms:play-services-ads:8.4.0'

after adding the above code you will get a sync now option at the top right corner of the page. Click on that and wait for a few minutes to complete the process, once the gradle building is finished you are ready to go with the next steps.

⟩⟩ Then open the Manifest file and add Internet permission to it.

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

⟩⟩  Now open MainActivity.java and add only line number 2 & 3 in public class as shown below

public class MainActivity extends AppCompatActivity {
InterstitialAd mInterstitialAd;
private InterstitialAd interstitial;
}

⟩⟩  Now open MainActivity.java and add below lines of code in onCreate() method

    AdRequest adRequest = new AdRequest.Builder().build();
        
        // Prepare the Interstitial Ad
        interstitial = new InterstitialAd(MainActivity.this);
// Insert the Ad Unit ID
        interstitial.setAdUnitId(getString(R.string.admob_interstitial_id));

        interstitial.loadAd(adRequest);
// Prepare an Interstitial Ad Listener
        interstitial.setAdListener(new AdListener() {
            public void onAdLoaded() {
// Call displayInterstitial() function
                displayInterstitial();
            }
        });

⟩⟩  Then add below lines of code before the last curly bracket of MainActivity.java 

public void displayInterstitial() {
// If Ads are loaded, show Interstitial else show nothing.
if (interstitial.isLoaded()) {
interstitial.show();
}
}

⟩⟩  Now open string.xml file in values folder and paste the below line of code.

<string name="ad_unit_id">ca-app-pub-39402560999xxxxx/21772xxxxx</string>

Interstitial AdMob ID used here is a sample ID. In order to get revenue, you need to replace this test ID with your own Interstitial Ad ID.

If you don’t know how to get your own Interstitial Ad Id then check this guide on how to get Interstitial Ad Unit ID.

Note: Don’t use your real Ad Unit ID while testing and never click on your own Ads it is against AdMob Policy.

That’s it, friends, this is the correct and simple way to insert Interstitial Ad in your Application. Just follow the above steps and copy paste the code carefully at the correct location mentioned above.
