MRAID "exposureChange" event is not fired

[Hideyoshi Moriya]

Hi Google Mobile Ads SDK team,

# Environment

- iOS Mobile Ads SDK version: 7.60.0

- Model and iOS version: iPhone 11 Pro (iOS 13.4.1) / iPhone Simulator iPhone X (iOS 11.0.1)

# Example code

- iOS: https://github.com/a42inc/GMA_MRAID_Example/tree/master/iOS/GMA_MRAID_Example

- Ad Creative: https://github.com/a42inc/GMA_MRAID_Example/blob/master/ad_creative/index.html

Note: If my ad manager ad unit code is needed for testing, please contact me.

# Issue 

The MRAID "exposureChange" event (https://developers.google.com/ad-manager/mobile-ads-sdk/ios/mraid#viewability_-_exposurechange_event) is not fired.

In my iOS code above, an ad banner view is added on top of UIScrollView. The MRAID's "exposureChange" event should be fired when a part of the ad banner view is off screen. However, the "exposureChange" event is not fired. In the example app, you can check if the "exposureChange" event is fired via app event delegate.

Ad creative HTML

mraid.addEventListener('exposureChange', (exposedPercentage, visibleRectangle, occlusionRectangles) => {
    admob.events.dispatchAppEvent("mraid", `exposureChange: ${exposedPercentage}`);
});

iOS

func adView(_ banner: GADBannerView,
                didReceiveAppEvent name: String,
                withInfo info: String?) {
    guard let info = info else {return}
    print("\(name) - \(info)")
}

# Expected behavior

The MRAID "exposureChange" event is fired whenever the percentage of ad container exposure has changed.

Refs:

- https://developers.google.com/ad-manager/mobile-ads-sdk/ios/mraid#viewability_-_exposurechange_event

- https://www.iab.com/wp-content/uploads/2017/07/MRAID_3.0_FINAL.pdf

# Other info

- The "exposureChange" event was fired normally about a year ago as far as I know.

- Other MRAID events (viewableChange, ready) are fired normally.

- The "audioVolumeChange" event is also not fired.

- It seems it's not an issue in the client side SDK but a script which is loaded in the SDK because the event is not fired with the exact same code and old SDK (7.43.0).

Thanks,

Hi there,

Thank you for providing an extensive rundown of the issue. For us to investigate further, would it be possible for you to provide a Charles log (see instructions here) capturing the ad? This will help and enable to test the ad on our test App environment by trafficking the creative in the test network.
Kindly send the requested details via Reply privately to author option.

Hi there,

I work with Teejay and will be assisting you today. Thank you for the Charles log. I was able to find the ad unit Id you made and use it in the app. The creative that came up was able to send the callback for viewable change of false and true but not percentage of view changed. Let me consult with the rest of my team. I will get back to you as soon as we have more information.

Kind regards,
Aryeh Baker

Hi Aryeh and team,

Thanks so much for your investigation on this.

Would you mind giving me updates or estimated time to fix the issue?

Please let me know if there's anything I can help you with.

Best regards,

Hideyoshi

Hi Hideyoshi,

My team is looking into it now. When we have more information we will get back to you. Thank you for your patience.

Hi Hideyoshi,

I work along with Aryeh. 

The team provided their feedback that the issue is not reproducible on the latest version of the SDK (7.60.0). Could you please confirm if the behavior occurs to on your end with the said version?

Regards,
Teejay Pimentel

[Hideyoshi Moriya]

Hi Teejay,

Thanks for your reply and investigation.

I tried again with the latest SDK version (7.60.0) and confirmed the issue is still reproducible.

I've already provided the example code and Charles log with your team before.

Would mind giving me an example code which can confirm if The MRAID "exposureChange" event is fired?

Also, just in case, it would be appreciated if you could check the behavior with an external (non-Google) network because this issue might not happen within Google's internal network.

Thanks,

Hideyoshi

Hi Hideyoshi,

I retested your app making sure that podfile.lock had the latest SDK version and I found that the exposure call wasn't triggering. Let me raise this and your comments with the rest of the team. We will get back to you the soonest we have more information.

Kind regards,
Aryeh Baker

Hi Aryeh,

Thanks for the update.

I suspect there might be an issue on a script which is loaded inside the SDK because the "exposureChange" event used to be fired (at least a year ago) as expected.

I'm looking forward to getting back from you.

Thanks!

Hi Hideyoshi,

That sounds plausible, especially as you reported that it was working a year ago on old SDK and doesn't work on old SDK anymore. I will bring up this suggestion too to the rest of the team.

[Hideyoshi Moriya]

Hi Mobile Ads SDK Team,

Any updates on this? Thanks!

Hi Hideyoshi,

 

Thank you for your patience on this issue.

 

The team is still currently investigating on this. The latest finding we have so far is that there might be some js code that was being unnecessarily injected in the ad HTML, which might be causing this issue. Rest assured that we'll keep you updated on this.
