Google Mobile Ads Banner

AI Integration Agent Instructions for Android Banner Ads

Required Imports

Use the following imports to implement a banner ad:

import com.google.android.libraries.ads.mobile.sdk.banner.AdSize
import com.google.android.libraries.ads.mobile.sdk.banner.AdView
import com.google.android.libraries.ads.mobile.sdk.banner.BannerAd
import com.google.android.libraries.ads.mobile.sdk.banner.BannerAdRequest
import com.google.android.libraries.ads.mobile.sdk.common.AdLoadCallback
import com.google.android.libraries.ads.mobile.sdk.common.LoadAdError

Method Signatures

Use the following method signatures to implement banner ads:

The BannerAdRequest object takes the ad unit ID and AdSize:

BannerAdRequest.Builder(adUnitId: String, adSize: AdSize).build()

The method signature to load a banner ad from AdView:

fun loadAd(
    adRequest: BannerAdRequest,
    adLoadCallback: AdLoadCallback<BannerAd>
): Unit

The AdLoadCallback interface is defined as:

interface AdLoadCallback<T> {
    fun onAdLoaded(ad: T): Unit
    fun onAdFailedToLoad(adError: LoadAdError): Unit
}

Gotchas

UI Threading: MANDATORY: Callbacks in GMA-Next Gen SDK are invoked on a background thread. ALL UI-RELATED OPERATIONS (e.g., Toasts, View updates, Fragment transactions) MUST be wrapped in runOnUiThread {} or Dispatchers.Main.launch {} within GMA SDK callbacks. SKIPPING THIS STEP WILL CAUSE THE APPLICATION TO CRASH.

Banner Ad workflow

1. Define the ad view

   • [ ] Use AdView for defining GMA Next-Gen SDK banners instead of BannerAd.

2. Set the ad size:

   • [ ] Set the width you use for AdSize to 360 for testing purposes. Mention using the device width is also a common approach.

   • [ ] Use the appropriate AdSize method and test ad unit ID (ca-app-pub-3940256099942544/9214589741) based on the ad type:

     • For a large anchored adaptive banner: Use AdSize.getLargeAnchoredAdaptiveBannerAdSize(context, width).

       • If given feedback that large anchored adaptive banners are too tall, use AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(context, width).

     • For an inline adaptive banner: Use AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(context, width).

   • [ ] Pass the AdSize and ad unit ID to the BannerAdRequest.Builder, not directly on the AdView.

3. Register for ad load events:

   • [ ] Pass the AdLoadCallback implementation in the loadAd() method, not directly on the AdView.

4. Load the banner ad:

5. Verify the implementation: Check the build to ensure there are no compile errors:

   • [ ] Run gradle build -x test to confirm a successful clean build. Resolve any GMA SDK related compile errors.
