NativeAds crashing a lot (5K crash in one day)

[Ahmadul Hoq]

Hi, for the past couple of weeks we're seeing a spike in NativeAds crash. It's one of those crashes which we're unable to reproduce. But in Firebase Crash Reporting, we can see the number is quite high, and it was so far about 5k crashes in the last 24 hours.

FYI, we use Google AdMob mediation and our ads come Facebook and Google. From the analytics tags on the Firebase crash reporting page, we can see that the crash happens couple seconds later the app launches, most likely when the ad is loaded. Can anyone please point me where the issue might be coming from?

Here's the stacktrace (I only have this):

Exception java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.ads.internal.renderer.nativeads.a.c()' on a null object reference

com.google.android.gms.ads.internal.formats.o.g (o.java:258)

Thanks!

Hi there,

This issue has been reported before and the team is actively investigating the root cause of the issue in order to provide a fix. The crash seems to occur when the Native Ad is being destroyed using the .destroy() method. Can you confirm if this is the true for your end?

Additionally, if you could provide the following information to help expedite the issue quicker, then it would be of great help:

• Affected Ad Unit IDs
• Complete Warning/Error logs captured from the device
• Logs from Charles' Proxy with SSL Proxying Enabled.
• A sample code snippet/project in where the issue can be reproduced.

This is in the "O" emulator released today.

Dunno if this is the same thing, but was getting this crash on orientation change, which shouldn't necessarily involve the destroy() but anyway...

I set up a Google account on the emulator, and now I see this, again when changing orientation.

Hi there,

We have a known issue about the crash log you provided and a fix has been made. However, I do not have a specific timeline on when this fix will be rolled out. You can regularly check our Release Notes in case a new version has been released and check if you can still replicate the crash.

However, since your issue does not seem to be related to the original post, you can open a new thread if you want to request for an update and we will continue our discussion from there.
