I can’t reproduce the problem.
Also everything looks fine when debugging in my devices.
What I know, from players with andoid 10 devices, is that the app closes after a minute or so. If I send them an apk without the appodeal block everything works fine.
Maybe there is something wrong with my build.settings or the way I do the initialization?
Also (don’t know if it helps) in this app version the impacted sessions are 0.09%, crash-free sessions 99,91%, number of sessions 40k.
I looked at what you posted. I don’t recognize the first crash. The second crash is the terrible libmonochrome crash. You are not alone. Usually, this is a playable ad with some nasty javascript. I don’t use StartApp or AdColony (the only two networks you have enabled).
The last StartApp version according to the changelogs for Appodeal is:
2.5.5 (June 20, 2019)
Fix Ads CountDown view crash during size changes
Fix issue with missing banners during animations
StartApp updated to 4.0.2
StartApp has produced many versions since then and I am not clear what they changed since I can’t find the change logs. You might benefit from updating this library manually until it breaks Appodeal.
The last AdColony version according to changelogs for Appodeal is:
2.5.10 (4 November, 2019)
AdColony updated to 4.1.0
Looking at changes since that version, I see that AdColony did address a webview issue with version 4.1.2. Manually updating AdColony up to that version might be beneficial if it doesn’t break Appodeal.
