将广告联盟 extra 传递给适配器

某些网络适配器支持在创建广告请求时传递给适配器的其他参数。这些参数称为“网络额外参数”。

Google 移动广告插件在 Android 和 iOS 上提供了 API，可让您将广告联盟额外信息传递给中介适配器。为此，您需要在 Android 上实现 MediationNetworkExtrasProvider，在 iOS 上实现 FLTMediationNetworkExtrasProvider，然后向插件注册额外参数 提供程序实现。之后，插件会在 Android 或 iOS 上创建广告请求时使用该实现来传递广告联盟额外信息。

在 Android 上注册 MediationNetworkExtrasProvider

创建 MediationNetworkExtrasProvider 的实现：

class MyMediationNetworkExtrasProvider implements MediationNetworkExtrasProvider {

  @Override
  public Map<Class<? extends MediationExtrasReceiver>, Bundle> getMediationExtras(
      String adUnitId, @Nullable String identifier) {
    // This example passes extras to the AppLovin adapter.
    // This method is called with the ad unit of the associated ad request, and
    // an optional string parameter which comes from the dart ad request object.
    Bundle appLovinBundle = new AppLovinExtras.Builder().setMuteAudio(true).build();
    Map<Class<? extends MediationExtrasReceiver>, Bundle> extras = new HashMap<>();
    extras.put(ApplovinAdapter.class, appLovinBundle);
    // Note: You can pass extras to multiple adapters by adding more entries.
    return extras;
  }
}

然后向 GoogleMobileAdsPlugin 注册该实现：

// Register a MediationNetworkExtrasProvider with the plugin.
public class MainActivity extends FlutterActivity {

  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    super.configureFlutterEngine(flutterEngine);

    // Register your MediationNetworkExtrasProvider to provide network extras to ad requests.
    GoogleMobileAdsPlugin.registerMediationNetworkExtrasProvider(
        flutterEngine, new MyMediationNetworkExtrasProvider());
  }
}

您可以在特定网络的 Android 参考文档中查看不同网络支持哪些额外参数以及如何 构建这些参数。

在 iOS 上注册 FLTMediationNetworkExtrasProvider

创建 FLTMediationNetworkExtrasProvider 的实现：

@implementation MyFLTMediationNetworkExtrasProvider

- (NSArray<id<GADAdNetworkExtras>> *_Nullable)getMediationExtras:(NSString *_Nonnull)adUnitId
                                       mediationExtrasIdentifier:
                                           (NSString *_Nullable)mediationExtrasIdentifier {
  // This example passes extras to the AppLovin adapter.
  // This method is called with the ad unit of the associated ad request, and
  // an optional string parameter which comes from the dart ad request object.
  GADMAdapterAppLovinExtras *appLovinExtras = [[GADMAdapterAppLovinExtras alloc] init];
  appLovinExtras.muteAudio = NO;
  // Note: You can pass extras to multiple adapters by adding more entries.

  return @[ appLovinExtras ];
}
@end

然后向 FLTGoogleMobileAdsPlugin 注册该实现：

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GeneratedPluginRegistrant registerWithRegistry:self];

  // Register your network extras provider if you want to provide
  // network extras to specific ad requests.
  MyFLTMediationNetworkExtrasProvider *networkExtrasProvider =
      [[MyFLTMediationNetworkExtrasProvider alloc] init];
  [FLTGoogleMobileAdsPlugin registerMediationNetworkExtrasProvider:networkExtrasProvider
                                                          registry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

@end
