Integrating AdMob Ads

To integrate AdMob ads into your app, follow these steps:

1. Create an AdMob Account: Go to the AdMob website and create a new account. Fill out the registration form and follow the instructions to set up your account.
2. Generate AdMob App ID and Ad Unit ID: After creating your account, you will be given an App ID and Ad Unit ID. Note down these IDs as you will need them later.
3. Add AdMob to the App: Open the Android Studio project and navigate to the app/build.gradle file. Add the following code to the dependencies section:

   dependencies {
   implementation 'com.google.android.gms:play-services-ads:20.6.0'
   }

4. Create an AdMob Layout: Create a new XML layout file (ad_layout.xml) in the res/layout directory:

   
   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical">
   
   <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_centerVertical="true">
   
   </com.google.android.gms.ads.AdView>

5. **Add the AdMob Ad**: In the `activity_main.xml` file, add the following code to add the AdMob ad:
```xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- Add AdMob Ad -->
    <include layout="@layout/ad_layout"/>

    <!-- Scan Button -->
    <Button
        android:id="@+id/scan_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Scan"/>

</LinearLayout>

1. Initialize AdMob in the Code: In the MainActivity.java file, add the following code to initialize AdMob:

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

public class MainActivity extends AppCompatActivity {

private AdView adView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Initialize AdMob
    MobileAds.initialize(this, "YOUR_APP_ID");
    adView = findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);
}

}

Replace `YOUR_APP_ID` with your actual AdMob App ID.
