Flutter, Native Admob, Ad failed to load : 0

Question

https://pub.dev/packages/google_mobile_ads

I copied this example

and everything is working fine except "Native Ad"

Of course, MainActivity.kt and NativeAdFactoryExample.kt are all set perfectly

and of course I used testAdUnitId for NativeAd

but it keeps show

I/Ads     ( 6932): Received log message: <Google:HTML> Incorrect native ad response. Click actions were not properly specified
I/Ads     ( 6932): Ad failed to load : 0
I/flutter ( 6932): NativeAd failedToLoad: LoadAdError(code: 0, domain: com.google.android.gms.ads, message: Internal error.)

I`m working on it for 12hours and it`s still not solved and I am really getting crazy

Could anyone help this problem please?

Answer 1

So i came up against this and could not get it to work until i found this https://github.com/googleads/googleads-mobile-flutter/issues/399 so making your ad widget use the auto keep alive mixin apparently helps, i tried that with my code and it would not work i then used the example in the link which did work, the only difference i can see is he is creating an instance of the ad in init state and then calling .load() on that instance, where as i was using the dart notation and creating the instance and calling ..load() in the same call Object()..load() i think these things are usually identical but i switched to his version and it worked. Below is the example the only i thing i swapped was the style from using the factoryId to specifying a style

      class NativeInlineAd extends StatefulWidget {
    const NativeInlineAd();
  
    @override
    State createState() => _NativeInlineAdState();
  }
  
  class _NativeInlineAdState extends State<NativeInlineAd>
      with AutomaticKeepAliveClientMixin {
    // COMPLETE: Add NativeAd instance
    late NativeAd _ad;
  
    // COMPLETE: Add _isAdLoaded
    bool _isAdLoaded = false;
  
    @override
    void initState() {
      super.initState();
  
      // COMPLETE: Create a NativeAd instance
      _ad = NativeAd(
        adUnitId: kReleaseMode
            ? '<YOUR_NATIVE_ADMOB_ID>'
            : '<NATIVE_TEST_AD_ID>',
        factoryId: 'googleNativeAdsCard',
        request: const AdRequest(),
        listener: NativeAdListener(
          onAdLoaded: (_) {
            setState(() {
              _isAdLoaded = true;
            });
          },
          onAdFailedToLoad: (ad, error) {
            // Releases an ad resource when it fails to load
            ad.dispose();
  
            throw 'Ad load failed (code=${error.code} message=${error.message})';
          },
        ),
      );
  
      // COMPLETE: Load an ad
      _ad.load();
    }
  
    @override
    Widget build(BuildContext context) {
      super.build(context);
      if (_isAdLoaded) {
        return Container(
          child:  SizedBox(height: 200, child: AdWidget(ad: _ad)),
          ),
          height: 270,
          margin: const EdgeInsets.only(
            left: 10,
            right: 10,
            top: 5,
          ),
          padding: const EdgeInsets.all(8),
          decoration: BoxDecoration(
            borderRadius: BorderRadius.circular(
              ValuesConstant.borderRadius,
            ),
            border: Border.all(
              width: 1,
              color: Colors.black,
            ),
            color: Theme.of(context).cardTheme.color,
          ),
          alignment: Alignment.center,
        );
      }
      return const SizedBox(
        height: 72.0,
        child: Center(
          child: CircularProgressIndicator(
            valueColor: AlwaysStoppedAnimation<Color>(
              Colors.grey,
            ),
          ),
        ),
      );
    }
  
    @override
    void dispose() {
      _ad.dispose();
      super.dispose();
    }
  
    @override
    bool get wantKeepAlive => true;
  }

Answer 2

if your code is fine and also you are using an emulator with google play. just set your app-ads.txt which can be found in your all apps on google AdMob

Google will crawl the URL (root URL of your website) and find these apps requesting or serving ads.

If your code is OK, then nothing to worry about. just try again on other emulator with "google play" or try with live device.
