Usa API specifiche per la rete

Le reti di mediazione possono fornire API nei propri SDK per Android e iOS che consentono di personalizzare ulteriormente gli annunci. Puoi chiamare queste API dal codice Dart utilizzando un canale della piattaforma.

L'esempio seguente mostra come chiamare le API di privacy negli SDK di AppLovin per Android e iOS da Dart.

Creare un canale di metodo in Dart

Nel codice Dart, crea un canale di metodo:

/// Wraps a method channel that makes calls to AppLovin privacy APIs.
class MyMethodChannel {
  final MethodChannel _methodChannel =
      MethodChannel('com.example.mediationexample/mediation-channel');

  /// Sets whether the user is age restricted in AppLovin.
  Future<void> setAppLovinIsAgeRestrictedUser(bool isAgeRestricted) async {
    return _methodChannel.invokeMethod(
      'setIsAgeRestrictedUser',
      {
        'isAgeRestricted': isAgeRestricted,
      },
    );
  }

  /// Sets whether we have user consent for the user in AppLovin.
  Future<void> setHasUserConsent(bool hasUserConsent) async {
    return _methodChannel.invokeMethod(
      'setHasUserConsent',
      {
        'hasUserConsent': hasUserConsent,
      },
    );
  }
}

Modificare il codice Android

Configura un canale di metodo per effettuare chiamate API all'SDK AppLovin in Android:

public class MainActivity extends FlutterActivity {
  private static final String CHANNEL_NAME =
    "com.example.mediationexample/mediation-channel";

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

    // Set up a method channel for calling APIs in the AppLovin SDK.
    new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), CHANNEL)
        .setMethodCallHandler(
          (call, result) -> {
            switch (call.method) {
              case "setIsAgeRestrictedUser":
                AppLovinPrivacySettings.setIsAgeRestrictedUser(call.argument("isAgeRestricted"), context);
                result.success(null);
                break;
              case "setHasUserConsent":
                AppLovinPrivacySettings.setHasUserConsent(call.argument("hasUserConsent"), context);
                result.success(null);
                break;
              default:
                result.notImplemented();
                break;
            }
          }
        );
  }
}

Modificare il codice per iOS

Configura un canale di metodo per effettuare chiamate API all'SDK AppLovin in iOS:

@implementation AppDelegate

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

  // Set up a method channel for calling methods in 3P SDKs.
  FlutterViewController* controller = (FlutterViewController*)self.window.rootViewController;

  FlutterMethodChannel* methodChannel = [FlutterMethodChannel
                                          methodChannelWithName:@"com.example.mediationexample/mediation-channel"
                                          binaryMessenger:controller.binaryMessenger];
  [methodChannel setMethodCallHandler:^(FlutterMethodCall* call, FlutterResult result) {
    if ([call.method isEqualToString:@"setIsAgeRestrictedUser"]) {
      [ALPrivacySettings setIsAgeRestrictedUser:call.arguments[@"isAgeRestricted"]];
      result(nil);
    } else if ([call.method isEqualToString:@"setHasUserConsent"]) {
      [ALPrivacySettings setHasUserConsent:call.arguments[@"hasUserConsent"]];
      result(nil);
    } else {
      result(FlutterMethodNotImplemented);
    }
  }];
}
@end

Utilizzare MethodChannel in Dart

Ora puoi utilizzare MyMethodChannel per chiamare le API di privacy di AppLovin da Dart:

/// An example widget for the home page of your app.
class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  
  // Keep a reference to your MyMethodChannel.
  static MyMethodChannel platform = MyMethodChannel();
  
  @override
  void initState() {
    super.initState();

    _updateAppLovinSettingsAndLoadAd();
  }
  
  Future<void> _updateAppLovinSettingsAndLoadAd() async {
    // Update the AppLovin settings before loading an ad.
    await platform.setAppLovinIsAgeRestrictedUser(true);
    await platform.setHasUserConsent(false);
    _loadAd();
  }
  
  void _loadAd() {
    // TODO: Load an ad.
  };

  @override
  Widget build(BuildContext context) {
    // TODO: Build your widget.
  }
}
