Setting up banner ads in your application can be a great way to generate revenue. Here's a step-by-step guide on how to set up banner ads using Google AdMob, one of the most popular ad networks.

Step 1: Sign Up for Google AdMob

1. Create an AdMob Account:

   • Go to the Google AdMob website and sign up or log in with your Google account.

2. Set Up Your App:

   • Once logged in, click on "Apps" in the left-hand sidebar.
   • Select "Add app."
   • Follow the prompts to register your app (you can choose whether your app is already listed on an app store or not).

Step 2: Add AdMob SDK to Your Application 

                    

For Android:

1. Install the Mobile Ads SDK:

   • Add the following to your project-level build.gradle file:

dependencies {
    classpath 'com.google.gms:google-services:4.4.1'
    // ...
}

 

•  Add the following to your app-level build.gradle file:

dependencies {
  implementation 'com.google.android.gms:play-services-ads:23.1.0'
}

2. Initialize the SDK:

1. • In your AndroidManifest.xml file, add the following within the <application> tag:

     <meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" 
     android:value="YOUR_ADMOB_APP_ID"/>
     

Initialize the Mobile Ads SDK in your main activity:

Java

import com.google.android.gms.ads.MobileAds;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// Initialize the Mobile Ads SDK.

MobileAds.initialize(this, initializationStatus -> {});

}

Implement Banner Ad in Your App

For Android:

1. Add AdView to Your Layout: 

• In your XML layout file, add the following

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

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="YOUR_AD_UNIT_ID"/>

 

• Load the Ad:

• In your activity, load the ad with:

 

​​​​​​​JAVA

import com.google.android.gms.ads.AdRequest;

import com.google.android.gms.ads.AdView;

@Override.

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    AdView adView = findViewById(R.id.adView);

    AdRequest adRequest = new AdRequest.Builder().build();

    adView.loadAd(adRequest);

}

• Test Your Ads

​​​​​​​

• Test Ads:

Ensure you're using test ads during development to avoid policy violations. Use the test Ad Unit IDs provided by AdMob or configure your requests to use test devices.

• Publish Your App​​​​​​​

• Publish:

Once everything is set up and tested, you can publish your app on the Google Play Store or the Apple App Store.

By following these steps, you should be able to integrate banner ads into your application and start generating revenue. If you encounter any issues, the Google AdMob documentation is a great resource for troubleshooting and additional details.
