Sorry, we can not reproduce this crash. I just ran into the crash case for only once when app launching. The app is an online version. you can download the app from App Store, apple id = 1248716307.

And we don't have any other reports on other iOS versions and device models so far.

Hi Eric,

Thanks for providing to us the stack trace of the crash. However, it does not seem to be related to the original report of the first developer in this thread. While your crash log does contain symbols of the SDK (such as GADDiskUsageStatisticsWithError), the offset of the symbol is too high ( + 4377669496) for it to be coming from the SDK and is most likely caused by your implementation.

With that said, I would recommend that you review your implementation and check where the crash may be occurring.

On the other hand, if you are able to replicate the crash locally, then kindly provide to us a sample project, as well as other useful information such as Android OS versions, device models and SDK version used in a new forum thread where we can replicate the issue and we will be glad to assist you in finding out the cause of the crash.

Regards,

Joshua Lagonera

Hi Joshua,

Our publisher reported a similar crash to us, please refer to this crash link: http://crashes.to/s/1865270becb, and attached devices and OS version information.

They found it happened in GMA 7.21.0 and 7.27.0, they also cannot replicate this issue. Do you have any insights from this crash and is it related to GMA SDK?

App Id: 416048305

Thanks

Hi,

We have also found multiple of these crashes via Crashlytics. The only common denominator we have found is that devices had very little RAM free at the moment of the crash, below 5%, sometimes all the way down to 1%. The crash occurs on different versions of iOS 10.* and at least for 11.2.*

Also, looking at Crystal Wangs crash link, error message that can be read is "Out of memory. We suggest restarting the application. If you have an unsaved document, create a backup copy in Finder, then try to save.".

Could it be that GAD is using to much memory in some edge cases? We have not stumble up on this crash during developing, only on AppStore releases.

Hi there,

Thank you for providing the crash logs. While it does contain symbols from the SDK, the crash doesn't seem to be caused by the SDK and it seems to be more on your implementation, as indicated by the very large offsets (e.g. + 4297426672).

Can you check if you are able to replicate the crash from our sample projects? Additionally, for us to take a better look at what is causing the crash, can you provide to us the following information privately by using the Reply Privately to Author option?

A sample project showing your implementation of the Mobile Ads SDK.
If you are able to locally replicate the crash, then additional details on how to replicate it as well would be extremely helpful.
Metrics on how often the crash is happening.

Hi Joshua

It is highly unlikely you will be able to reproduce the crash, but recently our app has been rejected due to "crash on launch" with exactly the stacktrace of topic starter. Apple apparently was able to reproduce it. We are also unable to reproduce it locally. It might be a strange blend of `canMakePayments` implementatation and the context it is being called. Please notice that in the TS's stack trace offsets from your symbols are not that big, so it must be originating from the SDK code. Any ideas on how to mitigate this?

Hi Eugene,

Seeing as the originally reported stack trace is a bit old, can you provide to us the stack trace of the crash you are reporting for us to have a more updated reference? It would be helpful for us to investigate the source of the crash. Additionally, can you provide to us some information (such as the version of SDK you are using, iOS Versions, etc) about the environment when the crash occurred?

Regards,

Joshua Lagonera

Thanks for responding. Here are the details:

We were integrating GoogleMobileAds SDK v. 7.27 (I know that the most recent one is 7.29, but setting a symbolic breakpoint on +[SKPaymentQueeue canMakePayments] shows that it is being called in the same place in v. 7.29).

Here is the stacktrace from iOS 11.2.5 (assuming iPhone device type, but Apple reviewer has not revealed this detail). BuyAndSell is the name of our app module, notice that the app is killed by the system watchdog because it deadlocks. Hope the below helps:

Hi Eugene,

Thank you for providing the crash log, as well as additional insights about the crash. It is interesting to note that it contains StoreKit's canMakePayments method so it is possible that this is more on Apple's side rather than something specific with the SDK.

Regardless, I have forwarded this information to the rest of the team for investigation. I'll get back to this thread once I have any updates from the team.

Hi Eugene,

How did you go with this? I've just had the same rejection from Apple (See below). Did you just make a new build and resubmit? I can't think of anything to do to fix this myself. Seem like a case of bad luck :(

Hi Alan,

We are actively looking into this for you and will provide an update as soon as we have a resolution timeline. While the underlying issue is a known issue with Apple's StoreKit, we are looking into a solution to stop this crash from occurring on app launch.

Regards

Were you able to find a solution for this issue ? We are seeing a similar crash in our application as well (with the latest SDK available).

Kind regards,

Hi there,

we haven't nailed a specific solution since we're unable to replicate, however we have a few ideas that we will be testing in an upcoming release.

Are you seeing very many crashes? Is it preventing submission to the app store?

Hi Sam,

Yes, we do see many crashes (we are unable to use the application for more than one minute). So it does block our next release.

Kind regards and thanks for the feedback.

Hmm ok, so it's reproducing reliably?

Are you able to give us a minimal sample that reproduces the crash for us to investigate?

Bart,

Can you also please provide some crash logs so we can verify we are talking about the same issue. As far as we're aware, the [SKPaymentQueue canMakePayments] call is currently only made on app launch, so it wouldn't make sense to us if you're using the app for a minute and then it crashes, for this to be the cause.

Regards

Sam

Thank you for that crash report, that is actually a new crash report that I have not seen before. We were previously looking at [SKPaymentQueue canMakePayments], but the log you shared does not have that, instead it contains -[AVAudioSession currentRoute].

If others are seeing this crash, or other crashes not containing [SKPaymentQueue canMakePayments], can you also please share?

We suspect that the GADDiskUsageStatisticsWithError is not the actual cause of the crash, but need more data points, and where possible a reproducing sample, to be able to take any specific actions.

Cheers

Sam

I am having the same issue, looks like AdMob is observing didFinishLaunch and then tries to log some statistics. It tries to access [SKPaymentQueue canMakePayments], but this function never returns and therefore app freezes.

We added another attempt to resolve this issue in 7.33.0 release, can you please update to the latest SDK (7.33.1) and advise if the issue still occurs?

Regards

Sam
