Hi @JackPS9 . Have you found the solution?

 

I have the same issue

 

I'm having the exact same problem. My game is built using Unity 2018.3.0f2, Advertisement package version 2.3.1 and il2cpp backend.

The crash seems to be quite random. Unfortunately I am not able to reproduce it on my device, but the game regularly crashes at launch on a few devices during the pre-launch tests in the Google Play Console.

This is the device where the crash happened more often:

Screen Size 1080 × 1920
Screen Density (dpi) 480
Model Name Mate 9
RAM 4096 MB
Manufacturer Huawei
OpenGL ES Version 3.2
Android Version Android 7.0
Native Platform armeabi-v7a
Locale en_US
CPU Make HiSilicon
CPU Model KIRIN960

These two lines of the stack trace suggest the crash originates from the Unity Ads plugin:

Can someone from the Unity team shed some light on this issue? @Yury-Habets @NinjaCat @JuliusM

 

I've had this no implementation found for reflection helper exception for analytics and IAP:

The problem doesn't seem to occur anymore after upgrading to the latest Unity Ads SDK from the Asset Store.

 

I have the latest SDK installed and still receive these crashes. The Unity Ads SDK on the asset store was last updated Oct 25, 2018 so I'm not sure if you downloaded a newer update elsewhere?

 

Same here, any help from Unity?

 

Also experience this on Unity2018.3.2f1, no solution yet from my side.

 

facing the similar issue.
Anyone solved this crash issue

I've also been getting crash reports from google play's pre-launch report. Most of which seam to come from unity ads.

They are intermittent, usually just 1 or 2 of the ~9 devices they randomly choose to run their automated test on. I have tried changing the version of the ads sdk using package manager but so far it doesn't seam to have worked ( though there is a long turnaround time to get a new launch report as I can't repro the issue locally )

Here is the latest stack trace I got in case its helpfull

Same problem here! Since Unity 2018.3, now we are using 2018.3.2f1.

Any patch to solve this please? We are having thousand crashes on google play console...

Just been through much the same set of issues and solutions as people are mentioning here. Here is the full solution that has worked for me. Using Unity 2018.3.0f2. Upgrade to latest Monetization SDK (3.0.1 I think, import it from asset store). Then on services tab of editor, open ads settings, and uncheck the box that says 'Enable built in ads extension' (which is hiding in the Advanced bit under Ads). Then Unity will most likely then complain about multiple references to the same package, so ...… edit the file YourProject/Packages/manifest.json and delete the line specifying dependency on Inbuilt Ads (find it using standard file explorer outside of Unity Editor because the Editor hides it from you, then open in WordPad or something and delete line that mentions unityads 2.3.1, or whatever version yours says that is pre 3.0, and save the amended file). Then, back in Unity Editor, if you look in the Packages folder of your project, you will see the Advertisements folder magically disappear (it doesn't let you simply delete that folder hence the editing of the json file). You'll also have a warning in Services-Ads about importing latest package or re-enabling built in ads, which is fine since you've already done just that. You'll have to rewrite your scripts that handle the ads to use UnityEngine.Monetization instead of UnityEngine.Advertisements (except for banners which use Advertisements) - instructions available online. Finally build with IL2CPP backend, C++ compiler configuration to master build if building a production ready bundle, and enable all architectures (ARMv7, ARM64, x86). You might also have to update your scripting runtime version to .NET 4.x (I seem to remember it moaning about that to me!) Since doing this lot, I've had zero crashes which makes me happy, and since ARM64 is included in the app bundle, this means I'm ready for the Google requirement of 64 bit support which is going to become a requirement this year. All I need to do now is turn my crash free Ads revenue stream into something that is actually meaningful and then I'll be double happy. Hope this helps anyone who is stuck with crashing ads though.

 

This looks like an issue I wasted weeks on! Does this happen when the ad is closed by the user? There is a known bug that is causing crashes when the user closes the ad.

The solution for now - which is a hack but works - is to create a private boolean i.e. adClosed = false. On the callback handler for when the ad is closed just set adClosed = true. Then in an Update function have if(adClosed) {do whatever you want i.e. change scene, pop UI etc.}.

It's not great as you have to have an update function, but it works. The bug won't let you call other classes in the callback handler, but a local variable works fine. Another dev said it should be a static variable, but I found it to work even when it wasn't static.

Hope this helps!!!

 

Guys, I think your problem is related to my. Look here: https://forum.unity.com/threads/cra...018-3-when-use-androidjavaproxy-class.627637/
I posted this few days ago and still no any answer from Unity staff.

 

I'm seeing this same exact issue in pre-launch unfortunately.

 

Same problem. Any solutions yet?

Correction: it still happens, just less often...

 

This seems to be a major issue. I have tried all the solution present here but the issue still exists. It has crossed the bad behaviour limit on Google.

I also have those errors with il2cpp backend.(with/out Proguard, with/out stripping,...) (Unity 2018.3.8)

The quick fix is to use mono... 0 errors.

 

Try setting target API level = 29 instead of highest installed. And if you use Appodeal of Apploving try deleting the rewarded videos and rewarded callbacks.

It fixed the problem on 3 out of 4 Android 11 devices. But that is better than crash on every Android 11 device.
