How to use ads in android studio ?? ( Ads )
Add in build.gradle
implementation 'com.google.android.gms:play-services-ads:22.6.0'
Add this to manifest file
<manifest>
<application>
<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy "/>
</application>
</manifest>the android:value will be your "appkey"Add the following code to your MainActivity is can only we add once
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;
public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MobileAds.initialize(this, new OnInitializationCompleteListener() {
@Override
public void onInitializationComplete(InitializationStatus initializationStatus) {
}
});
}
}Implementing banner ads
Create it in xml
# main_activity.xml
<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>or you can create programmatically
AdView adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
// TODO: Add adView to your view hierarchy.Implementing Interstitial ads
InterstitialAd.load(this,"your ads key", adRequest,
new InterstitialAdLoadCallback() {
@Override
public void onAdLoaded(@NonNull InterstitialAd interstitialAd) {
// The mInterstitialAd reference will be null until
// an ad is loaded.
mInterstitialAd = interstitialAd;
Log.i(TAG, "onAdLoaded");
mInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback(){
@Override
public void onAdClicked() {
// Called when a click is recorded for an ad.
Log.d(TAG, "Ad was clicked.");
}
@Override
public void onAdDismissedFullScreenContent() {
// Called when ad is dismissed.
// Set the ad reference to null so you don't show the ad a second time.
Log.d(TAG, "Ad dismissed fullscreen content.");

}
@Override

}
@Override

}
@Override
public void onAdShowedFullScreenContent() {

}
});
if (mInterstitialAd != null) {
mInterstitialAd.show(MainActivity.this);
} else {

}
}
@Override

}
});
App Open Ads
Just simply create new java file call OpenAppAdd and copy below code
Don't Forget To Chanr your ads key

Change Application name in manifest file to java file name like :
<application
android:name=".OpenAppAdd"
android:allowBackup="true"
