# AdMob Integration

shared/src/commonMain/kotlin/modules/common/ads/ads.kt

### Integrating AdMob with Your Application

**Overview:**

This document outlines the steps involved in integrating AdMob into your KMM application to display interstitial ads.

**Prerequisites:**

* A Google AdMob account is required.
* A KMM project set up.
* The `google-services.json` file provided by Google placed in the root directory of your Android application module.

**Integration:**

1. **Ad Unit ID:** Obtain the Ad Unit ID from your AdMob account and store it in Credentials file `shared/src/commonMain/kotlin/configs/Credentials.kt`.
2. **AdMob Implementation:**

   * Create a composable function that utilizes the `interstitialAd` function:

   Kotlin

   ```
   @Composable
   fun ShowInterstitialAd() {
       val ad = interstitialAd(adUnitId)

       ad.show()
   }
   ```
3. **`interstitialAd` Function:**
   * The `interstitialAd` function is defined in the `shared/src/commonMain/kotlin/modules/common/ads/ads.kt` file.
   * It's responsible for creating and handling the interstitial ad.
   * The specific implementation might vary depending on the AdMob library you're using, but it typically involves:
     * Creating an interstitial ad object.
     * Loading the ad.
     * Showing the ad when ready.
     * Handling ad events (e.g., impression, click, close).

**Additional Considerations:**

* Refer to the AdMob documentation for detailed information on specific implementation steps and best practices.
* Test your AdMob integration thoroughly to ensure proper ad display and tracking.

By following these steps and leveraging the `interstitialAd` function, you can effectively integrate AdMob into your KMM application to display interstitial ads and generate revenue.
