Hello,

I am using SDK 7.1.0 and i am getting this crash when i load admob full screen ad.

I read that this is related with the new youtube API. Is this fixed on SDK 7.2.1?

Hi Roberto,

I find nothing in the stack trace to indicate that the crash is from the mobile Ads SDK. Could you please try this on SDK sample and check if you are able to reproduce this issue?

Thanks,

Elton

Hello,

i cant reproduce this bug locally. I is only happening to 3% of users.

I am using Breadcrums, and this only happen when ads are visible, also i don't use any web-view on my app.

This bug started on 14 April.

According to this link, some people have the same issues with youtube SDK.

here is full logs of some of the crashes.

Hi Andrew, is there any update on this issue?

Yesterday we registered this exact same crash ~1100 times using SDK v7.5.2. The only SDK our app includes that uses UIWebViews is the Google Mobile AdMob SDK.

Here you can find a list of all the WebCore crashes we have:

I thought this one had been resolved, but it's possible that it hasn't. I'll reopen our issue report on it and add your stack traces to the notes.

Thanks for posting them!

This is seriously affecting my app (Snappp). Crashlytics has recorded this crash 3644 times, affecting over 1000 users. I was on the 7.6 SDK but for now have reverted back to 7.4, though I couldn't tell you if this fixed the issue until I submitted it and it got into the hands of many users. Sounds like this issue has been around since before then.

For some reason, this crash started happening in large numbers around December 9th. It existed before, but it became a big problem on that day forward. My guess is it's something server-side that's being sent down that's making the app crash. A specific advertiser's ad, maybe?

I'm thinking this could actually just be a WebKit bug, because I can't imagine how the AdMob SDK could do something to get WebGL rendering to crash.

WebKit is my guess as well. I know this one is still being looked at to see if we can find a workaround. Would you mind posting any stacktraces and device/OS details you have, if they're different from the ones already listed?

I'm having the same issue and in just 48 hours I got over 24k crashes due to this Webcore thing. Here is my backtrace, this started happening once my new update went live integrating Admob SDK.

Hi All,

I am also seeing this weird crashes recently, from the web I got 3 causes

1. Youtube player :- Which my app is not using
2. OpenGLES background calls :- No openGLES features in App directly
3. Admob:- I use it for conversion tracking

From my analysis 1&2 looks not to be the cause. I would like to check if Admob has anything to do with this, I am trying to figureout where is the cause as stacktrace is not giving much info, anything recently changed with the way Admob works??

thanks

Does anyone know if the issue goes away with the latest AdMob SDK, v7.7.1 ?

Nope, we're using v7.7.1 and still getting thousands of crashes caused by WebCore (iOS 9 only).

I'm seeing this same problem with version 7.8.1 of the SDK.

Thanks to Firebase Crash, I've already caught about a dozen of these crashes (having just released the latest update to the App Store a few days ago). The stack trace is shown below (at least I hope it is... copy-and-paste is being finicky).

From what I've read elsewhere, it seems that this particular crash from WebCore::GraphicsContext3D::reshape(int, int) can happen if it's attempted while off-screen.

After investigating the problem further with the engineering team, we've come to the conclusion that this is an issue with the web view itself, rather than the Google Mobile Ads SDK. We're looking into ways to work around the problem, but don't have anything solid yet. In the meantime, it's likely that publishers will continue to see occasional webview crashes like this.

As I had mentioned, it seems that this particular crash happens if the web view is off-screen while being updated. In my case, I found a situation where I'll have the ad banner loaded, but then I'll have a Safari view open on top of my app's main view (via SFSafariViewController). If this happens, and the my ad banner attempts to refresh while the Safari window is open, it can crash the app.

What I've done as an attempt to workaround this problem is to set adBannerView.autoloadEnabled = false before loading the Safari viewcontroller and re-enabling the ad banner once the Safari view is dismissed.

Any progress on this issue? What do you recommend we do to resolve it?

I'm also seeing this crash, but I'm not using any banners in my app, only full screen interstitials which are preloaded (cached) on app startup.

We are also seeing a lot of these crashes. Approximately 40% of the crashes are attributed to this issues which is very high as there seems very little we can do to fix it. At least with the other 60% we can attempt to rectify them.

Are there any updates on this?

This is still happening, seeing it on my app as well. We only use interstitial ads if that helps at all. Has any progress been made on this issue over the last year and change?

Great to hear that! I'm too using interstitials. Unfortunately I can't reproduce it locally but here are my two most common crash logs:

I just enabled Interstitial ads in my app for the first time yesterday (was using smart banners only before), and since I made this change the app is now crashing with this same error. WebCore::GraphicsContext3D::reshape(int,int)

Any ideas when you'll fix it??
