Can't show maps on Android, while it can shows on iOS – Flutter

I got a problem on showing maps on Android with Flutter here_sdk/Here Maps SDK. I’m running basic hello_map_app and already fill the credentials (access key id and access key secret) then failed to show the map when running to Android. But if I build and run for iOS, it can shows the map. Is there something that i missed?

Android

iOS

the code that I used

here-sdk-exampes/hello_map_app

  // Usually, you need to initialize the HERE SDK only once during the lifetime of an application.
  _initializeHERESDK();

  runApp(MyApp());
}

void _initializeHERESDK() async {
  // Needs to be called before accessing SDKOptions to load necessary libraries.
  SdkContext.init(IsolateOrigin.main);

  // Set your credentials for the HERE SDK.
  String accessKeyId = "####"; // censored
  String accessKeySecret = "####"; // censored
  SDKOptions sdkOptions = SDKOptions.withAccessKeySecret(accessKeyId, accessKeySecret);

  try {
    await SDKNativeEngine.makeSharedInstance(sdkOptions);
  } on InstantiationException {
    throw Exception("Failed to initialize the HERE SDK.");
  }
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'HERE SDK for Flutter - Hello Map!',
      home: HereMap(onMapCreated: _onMapCreated),
    );
  }

  void _onMapCreated(HereMapController hereMapController) {
    hereMapController.mapScene.loadSceneForMapScheme(MapScheme.normalDay, (MapError? error) {
      if (error != null) {
        print('Map scene not loaded. MapError: ${error.toString()}');
        return;
      }

      const double distanceToEarthInMeters = 8000;
      MapMeasure mapMeasureZoom = MapMeasure(MapMeasureKind.distance, distanceToEarthInMeters);
      hereMapController.camera.lookAtPointWithMeasure(GeoCoordinates(52.530932, 13.384915), mapMeasureZoom);
    });
  }
}

I already fill the credentials both on main.dart, AndroidManifest.xml, and Info.plist, but still got the same result.
