Interstitial ads are full-screen ads that cover the whole UI of the app. This article shows you how to integrate Interstitial ads from AdMob into an Android app. Example –
allprojects { repositories
{
google()
jcenter()
maven
{
url "https: //maven.google.com"
}
}
} |
In the app-level build.gradle file, add the highlighted code to dependencies section.
dependencies { implementation fileTree (dir : 'libs' , include : [ '*.jar' ])
implementation 'com.android.support:appcompat-v7:26.1.0'
compile 'com.google.android.gms:play-services-ads:15.0.0'
|
Add the following code to Main Activity to initialize Mobile Ads SDK (this only needs to be done once in app lifecycle). You can find the app’s App ID in AdMob console.
package org.geeksforgeeks.geeksforgeeks;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.google.android.gms.ads.MobileAds;
public class MainActivity extends AppCompatActivity
{ protected void onCreate (Bundle savedInstanceState)
{
super .onCreate (savedInstanceState);
setContentView (R.layout.activity_main);
// Initialize the Mobile Ads SDK
MobileAds.initialize ( this , getString (R.string.admob_app_id));
}
} |
Add the highlighted code to Main Activity to show Interstitial Ad: MainActivity.class –
package org.geeksforgeeks.geeksforgeeks;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import com.google.android.gms.ads.AdListener;
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 interstitial;
@Override
protected void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialize the Mobile Ads SDK
MobileAds.initialize( this , getString(R.string.admob_app_id));
// create ad request
AdRequest adIRequest = new AdRequest.Builder().build();
// Create an instance of the InterstitialAd object
interstitial = new InterstitialAd(MainActivity. this );
// Set the Ad Unit ID
interstitial.setAdUnitId(getString(R.string.admob_interstitial_id));
// Load the Interstitial Ad
interstitial.loadAd(adIRequest);
// Prepare an Interstitial Ad Listener
interstitial.setAdListener( new AdListener() {
@Override
public void onAdLoaded() {
// Call displayInterstitial() function when the Ad loads
displayInterstitial();
}
});
}
public void displayInterstitial() {
// If Interstitial Ads are loaded then show them, otherwise do nothing.
if (interstitial.isLoaded()) {
interstitial.show();
}
}
} |
Add the Admob App Id and Interstitial Ad Id to string.xml strings.xml –
<? xml version="1.0" encoding="utf-8"?>
< resources >
< string name="admob_app_id">
ca-app-pub-3940256099942544~3347511713</ string >
< string name="admob_interstitial_id">
ca-app-pub-3940256099942544/1033173712</ string >
<!-- ca-app-pub-3940256099942544~3347511713
this is your admob app id -->
<!-- ca-app-pub-3940256099942544/1033173712
