Admob Interstitial Ads in Android – Admob Ads v-20.2.0

Hello Guys, In this tutorial, we will see how to implement Admob Interstitial Ads in Android. So to Implement Admob ads Open Android Studio and create a project. Now follow the below steps

Interstitial ads are full-screen ads that cover the interface of their host app. They’re typically displayed at natural transition points in the flow of an app, such as between activities or during the pause between levels in a game. When an app shows an interstitial ad, the user has the choice to either tap on the ad and continue to its destination or close it and return to the app.

We already Integrated Admob SDK in the last tutorial. If you haven’t read that. Check out here.

Let’s See the Code.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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">

    <Button
        android:id="@+id/interstitial_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:layout_centerInParent="true"
        android:textSize="20sp"/>

    <com.google.android.gms.ads.AdView
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="ca-app-pub-3940256099942544/6300978111">
    </com.google.android.gms.ads.AdView>

</RelativeLayout>

Note: For this Tutorial, I have implemented a Button to show Interstitial. So in your case implement as you like. Make Sure you follow Admob Policies.
