RewardedAdEvent.earnedReward never gets called on iOS about native_admob_flutter

[genox-wang]

try debugged onUserEarnedReward event

 case 'onUserEarnedReward':
      try {
        onEventController.add({
          RewardedAdEvent.earnedReward: RewardItem.fromJson(call.arguments)
        });
      } catch(e) {
        print(e);
      }

I found amount field is double, but try to parse it with int

I don't know wether amount always is double, so I try fix it like this.
because I only care whether user skip video or not

try {
  onEventController.add({
    RewardedAdEvent.earnedReward: RewardItem.fromJson(call.arguments)
  });
} catch (e) {
  onEventController.add({RewardedAdEvent.earnedReward: null});
}

Can you guys try the latest master and see if it works?

dependencies:
  native_admob_flutter:
    git:
      url: https://github.com/bdlukaa/native_admob_flutter.git

I tried just now but it is still doesn't work.

I still go from loaded, then I watch, then it fire showed then once I close it only fire closed.

flutter: *** Ad Loaded!
flutter: *** Ad showed
flutter: *** Ad closed

I also get this message, not sure if this relevant or not:

Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service

@bdlukaa i am facing this issue on IOS with the test reward ad (version ^1.2.4), same exact code works ok on Android. RewardedAdEvent.closed is called without issues but case RewardedAdEvent.earnedReward is not called.

[bdlukaa]

ooh wow. I'll investigate

And if I understand the behavior correctly. In Android, when I finished watching a video Ad and then I close it, it fires rewarded first before firing close. Is it supposed to be the same behavior in iOS ?

Yes its a correct behavior, rewarded trigger before close event .

[bdlukaa]

Sorry but I won't be able to work on this today, only tomorrow!

[shofizone]

Any update on this issue? I got a bad review for this.

[bdlukaa]

Hey, thanks for reporting this issue! Does this happen on Android too? Are you using Rewarded Ads or Rewarded Interstitial Ads?

[fly-qp]

Reward Ads - no not on android.
I no just did something like this because I dont want my users to be mad on me:

case RewardedAdEvent.closed: loadNext(); if (Platform.isIOS) onRewarded(); onEvent(); break;

[bdlukaa]

Hey! I could not reproduce this issue. What version of the plugin are you using?

[fly-qp]

native_admob_flutter: ^1.2.0

[bdlukaa]

I can confirm this is also happening on Android with the latest version!

[bdlukaa]

Okay I managed to fix it. Nothing wrong on the platform side. It was just a casting error on the dart side. I'll release a new version with the fix for it soon

[fly-qp]

Thanks man I appreciate it very much 😍💕
Please let me know when new version is out

[niypoo]

Published v1.2.1 with the fix for it.

I'm facing same issue now , I'm using last version native_admob_flutter: ^1.2.4

[bdlukaa]

I don't know what's wrong on the iOS side. It seems to be everything good.

Swift code:

            rewardedAd.present(fromRootViewController: (UIApplication.shared.keyWindow?.rootViewController)!) { () in
                self.channel.invokeMethod("onUserEarnedReward", arguments: [
                    "amount": self.rewardedAd.adReward.amount,
                    "type": self.rewardedAd.adReward.type,
                ])
            }

https://developers.google.com/admob/ios/rewarded-ads#display_the_ad_and_handle_the_reward_event

Kotlin code:

                rewardedAd!!.show(activity) { reward ->
                    channel.invokeMethod("onUserEarnedReward", hashMapOf<String, Any>(
                            "amount" to reward.amount,
                            "type" to reward.type
                    ))
                }

Dart code:

      case 'onUserEarnedReward':
        onEventController.add({
          RewardedAdEvent.earnedReward: RewardItem.fromJson(call.arguments)
        });
        break;

Anyone with experience knows what's wrong?

[niypoo]

What was the wrong at first time you have known about this issue?
I think at version 1.2.1

[bdlukaa]

What was the wrong at first time you have known about this issue?

The data parsing from RewardItem.fromJson(call.arguments). It was not working on Android too, but I fixed it an it's now working on Android. Idk why it doesn't work on iOS since the implementation is basically the same.

I can't test it on iOS since all the iOS implementation is made from the community. It'd be very helpful someone to help me out.

[niypoo]

So , can you disabled any data return like data of award , just trigger a event and see if the event trigger or not

[bdlukaa]

The fix for it may be vishwajit76@96189d8, can you try his fork? Still, I can't test it because I don't have an Apple env.

okay , give me a full fork repo url.

I can't test this fork,
it's gives to me when try initialize MobileAds.initialize

Unhandled Exception: 'package:native_admob_flutter/src/utils.dart': Failed assertion: line 23 pos 10: 'Platform.isAndroid': Android is the only supported platform for now

and also the initialize function refuse this argument rewardedInterstitialAdUnitId

The named parameter 'rewardedInterstitialAdUnitId' isn't defined.
Try correcting the name to an existing named parameter's name, or defining a named parameter with the name 'rewardedInterstitialAdUnitId'.

[bdlukaa]

I think I know where this error is coming from. GADAdReward#amount is NSDecimalNumber. It's probably just a parsing issue. I'll keep investigating

[bdlukaa]

https://stackoverflow.com/a/28268951/11622876 should be the fix for it.

Okay I will try it today, thanks

[zenkog]

Hi. Sorry don't mean to push, but any update? I'm behind on a deadline.

[zenkog]

And if I understand the behavior correctly. In Android, when I finished watching a video Ad and then I close it, it fires rewarded first before firing close. Is it supposed to be the same behavior in iOS ?

[zenkog]

No Problem. Thanks for the reply.

Sorry but I won't be able to work on this today, only tomorrow!
