# AI Migration Agent Instructions for the Google Mobile Ads SDK ## Migrate to the GMA Next-Gen SDK * When I ask to migrate to the "Next-Gen" SDK, **ALWAYS** look up the latest stable version for `com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk`. * Make sure the project meets the SDK requirements of `minSdk` 24 or higher and `compileSdk` of 35 or higher. * Replace the `com.google.android.gms:play-services-ads` dependency with the Next-Gen `com.google.android.libraries.ads.mobile.sdk:ads-mobile-sdk` dependency. * Resolve each `com.google.android.gms.ads.*` class to its specific counterpart in `com.google.android.libraries.ads.mobile.sdk.*`. * If the change involves the `com.google.android.gms.ads.mediation.Adapter` class, ask me if I'm sure I want to migrate this class before making the change. * **CRITICAL:** `MobileAds.initialize()` must be called on a background thread. * **CRITICAL:** Make sure `MobileAds.initialize()` is called **before** any other SDK methods (e.g., `MobileAds.setRequestConfiguration()`). Move any such calls to the initialization callback or after initialization is complete. * If `RequestConfiguration` is used, configure it using `InitializationConfig.Builder.setRequestConfiguration()` and pass the config to `MobileAds.initialize()`. Do not call `MobileAds.setRequestConfiguration()` separately before initialization. * **CRITICAL:** **Always** dispatch UI-related operations (e.g., view updates, Toasts) within GMA Next-Gen SDK callbacks to the UI thread (e.g., using `runOnUiThread` or `Main` dispatcher). This is MANDATORY as the GMA Next-Gen SDK callbacks are not guaranteed to be on the main thread. * **ALWAYS** use the value of the `com.google.android.gms.ads.APPLICATION_ID` meta-data tag from `AndroidManifest.xml` for `applicationId`. If you can't find it, ask me what the AdMob application ID is. * Preserve the `com.google.android.gms.ads.APPLICATION_ID` `<meta-data>` tag in the `AndroidManifest.xml` file. * Run a build/compile check. If there are **0 errors** related to the files you modified, no more references to `com.google.android.gms.ads`, and you've verified every step in the instructions, consider the migration complete. ### Banner ads * Declare the preferred `com.google.android.libraries.ads.mobile.sdk.banner.AdView` class to load a "Next-Gen" banner ad instead of the deprecated `BannerAd` APIs. * To check if a banner ad is collapsible, use `getBannerAd().isCollapsible()` on the `AdView` object. ### Native ads * The following APIs are now set on the `NativeAdRequest.Builder`: * `.setCustomFormatIds(customFormatIds: List<String>)` * `.disableImageDownloading()` * `.setMediaAspectRatio(mediaAspectRatio: NativeMediaAspectRatio)` * `.setAdChoicesPlacement(adChoicesPlacement: AdChoicesPlacement)` * `.setVideoOptions(videoOptions: VideoOptions)` * Remove all "Mute This Ad" logic and associated data structures as they are not supported in the GMA Next-Gen SDK. ### Ad preloading * Unless noted in the mapping table, Ad preloading methods are the same from the old SDK to the GMA Next-Gen SDK. The existing API signature stays the same, using the same parameters as before. ### API mapping This table covers the main classes and their GMA Next-Gen SDK equivalents. | Feature | Old SDK Import (`com.google.android.gms.ads...`) | GMA Next-Gen SDK Import (`com.google.android.libraries.ads.mobile.sdk...` ) | |:---------------------------|:-------------------------------------------------------------------------------------|:--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **Core** | | | | Initialization | `MobileAds` | `MobileAds`, `initialization.InitializationConfig` | | Ad Request | `AdRequest` | *Format specific* (e.g. `common.AdRequest`, `banner.BannerAdRequest`, `nativead.NativeAdRequest`) (Ad Unit ID is declared in `Builder`.
