Admob Ads app crashes occasionally on IllegalArgumentException

Question

I try to integrate AdMob ads and GooglePlay IAP into clean (hello world) cocos2d-js 3.5 project.

Occasionally (every 5th run) the application crashes and shows the exception bellow. This behavior started when I've integrated IAP. Clean AdMob integration is fine (or at least believed to be).

Up to now I only did the Java part (cocos code is not called except the main screen). I did upgrade the google-play-services_lib to 23 version.

The log dump:

Any hints? I can post some code snippets if you find it useful...

UPDATE:

It is likely bug on Google side as Dmitry mentioned. I can see these security warnings just before the crash. It shows that the bug causing ad is "World of Tanks"

Answer 1

I am having the same problem. I have an already released app and it seems that the Game Of War Ad is what's doing it.
