Dear, Friend in this blog we discussion google ad integration. Many companies work in client base & product base. Product base company in very very important ad integration in the app. Multiple types of AD available like a Facebook ad, start-up ad, google ad, etc. Today we learning google ad integration. 

Type of Google AD:

• Banner AD
• Interstitial Ad
• Rewarded Video Ad
• Native Ad

1.Banner Ad

- Banner Ads occupy only a portion of the screen depending on the ad size that is created. It comes in multiple sizes Standard, Medium, Large, Full-Size, Leaderboard, and Smart Banner. Smart banners are very useful when you target multiple device sizes and fit the same ad depending on the screen size.

2.Interstitial Ads

- Interstitial ads occupy the full screen of the app. Basically, they will show on a timely basis, between screen transition or when the user is done with a task.

Open AndroidManifest.xml and add MyApplication to tag.

<meta-data
    android:name="com.google.android.gms.ads.APPLICATION_ID"
    android:value="ca-app-pub-3940256099942544/6300978111"/>

Basically, it works like a stack where each view is stacked on top of the other

Create a drawable file for shadow view and assign name as image_shadow and add code in this file.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="10dp" />
    <gradient
    android:angle="270"
    android:centerX="300%"
    android:endColor="#99000000"
    android:startColor="#00000000"
    android:type="linear" />
    <size
    android:width="270dp"
    android:height="60dp" />
    <stroke
    android:width="1dp"
    android:color="#878787" />
</shape>
Now, xml file and add the below code into it and set this drawable file as view background

<androidx.appcompat.widget.LinearLayoutCompat

        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>
    <View android:id="@+id/view"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:background="@drawable/image_shadow"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>
    <androidx.appcompat.widget.AppCompatTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:textColor="@android:color/white"
        android:text="Write your text here"
        android:textSize="25sp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="@+id/view"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.LinearLayoutCompat>
