Required Plugins and Setup

1. Install the Capacitor AdMob Plugin:

bash

npm install @capacitor-community/admob
npx cap sync

2. Configure AdMob Plugin: Add the following to your capacitor.config.ts:

typescript

import { CapacitorConfig } from '@capacitor/core';

const config: CapacitorConfig = {
  plugins: {
    AdMob: {
      appId: 'ca-app-pub-xxxxxxxx~xxxxxxxx', // Your AdMob App ID
      testingDevices: ['YOUR_DEVICE_ID'], // For testing
    },
  },
};

Implementation Steps

Step 1: Initialize AdMob in your React app

typescript

import { AdMob, AdMobNative, NativeAdOptions } from '@capacitor-community/admob';

// Initialize AdMob
await AdMob.initialize({
  initializeForTesting: true, // Remove in production
});

Step 2: Create Native Ad Component

typescript

import React, { useEffect, useRef } from 'react';

const NativeAdComponent: React.FC = () => {
  const adRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    const loadNativeAd = async () => {
      const options: NativeAdOptions = {
        adId: 'ca-app-pub-xxxxxxxx/xxxxxxxx', // Your Native Ad Unit ID
        adSize: 'MEDIUM_RECTANGLE',
        position: 'CUSTOM',
        margin: 0,
        x: 0,
        y: 0,
      };

      try {
        await AdMobNative.createNativeAd(options);
        await AdMobNative.showNativeAd();
      } catch (error) {
        console.error('Error loading native ad:', error);
      }
    };

    loadNativeAd();

    return () => {
      AdMobNative.hideNativeAd();
    };
  }, []);

  return <div ref={adRef} id="native-ad-container" />;
};

Step 3: Platform-specific Configuration

For iOS (ios/App/App/Info.plist):

xml

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-xxxxxxxx~xxxxxxxx</string>
<key>SKAdNetworkItems</key>
<array>
  <!-- Add SKAdNetwork IDs -->
</array>

For Android (android/app/src/main/AndroidManifest.xml):

xml

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

Advanced Implementation with Custom Native Ad Layout

typescript

const CustomNativeAd: React.FC = () => {
  const [nativeAdData, setNativeAdData] = useState(null);

  useEffect(() => {
    const loadCustomNativeAd = async () => {
      try {
        const result = await AdMobNative.loadNativeAd({
          adUnitId: 'ca-app-pub-xxxxxxxx/xxxxxxxx',
          adFormat: 'NATIVE_ADVANCED',
        });
        
        setNativeAdData(result.nativeAd);
      } catch (error) {
        console.error('Failed to load native ad:', error);
      }
    };

    loadCustomNativeAd();
  }, []);

  return (
    <div className="native-ad-container">
      {nativeAdData && (
        <>
          <img src={nativeAdData.icon} alt="Ad Icon" />
          <h3>{nativeAdData.headline}</h3>
          <p>{nativeAdData.body}</p>
          <button onClick={() => AdMobNative.recordClick()}>
            {nativeAdData.callToAction}
          </button>
        </>
      )}
    </div>
  );
};

Best Practices

1. Test Thoroughly: Use test ad unit IDs during development

2. Error Handling: Always implement proper error handling for ad loading failures

3. User Experience: Ensure native ads blend seamlessly with your app's design

4. Performance: Load ads asynchronously to avoid blocking the UI

5. Compliance: Follow Google AdMob policies for native ad implementation
