Error inflating class com.google.android.gms.ads.AdView in android studio

I am trying to add an admod to a fragment. After adding the dependency in build.gradle, I still cannot inflating the admod class and display the admod on my XML. Any idea of what I have done wrong? Am I missing any setting?

Error message

android.view.InflateException: Binary XML file line #1095 in com.centslife.development:layout/mockup_spotreceiptdetail: Binary XML file line #1095 in com.centslife.development:layout/mockup_spotreceiptdetail: Error inflating class com.google.android.gms.ads.AdView

You are using very old version of ads sdk.Change it with the latest.

implementation 'com.google.android.gms:play-services-ads:19.1.0' Also you have to add meta data in your manifest file's application tags

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

You can try like this

<com.google.android.gms.ads.AdView

        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_unit_id"/>
