FATAL: Unity 2022.2.11 broke native Android crash reporting

[Tommigun1980]

Description

https://unity.com/releases/editor/whats-new/2022.2.11 contains the "fix":
“Android: Unity will no longer wrap native crashes into java exceptions on Android, as has been the case, and will correctly forward signals to the previous handlers.”

This seems to have broken native crash reporting on Android.

Newer Unity versions no longer print

06-09 01:21:59.724 13024 13052 D AppCenterCrashes: Saving uncaught exception.
06-09 01:21:59.726 13024 13052 D AppCenterCrashes: Saved JSON content for ingestion into /data/user/0/com.ACompanyNme.CrashMaster/files/error/200b8936-b830-4c68-8e3d-d55270b9dbb9.json
06-09 01:21:59.726 13024 13047 D AppCenter: Cleared pending log states
06-09 01:21:59.727 13024 13047 D AppCenter: Channel completed shutdown.

when the app crashes, and Crashes.HasCrashedInLastSessionAsync() never returns true.
Reverting to an older Unity version fixes the issue.

Older Unity versions perform some logging from Unity's AndroidRuntime when an app crashes, after which AppCenter saves the exception. Newer Unity versions don't do this, instead they log about forwarding signals, and AppCenter never saves the crash.

This is of course a fatal issue as newer Unity versions contain mandatory fixes but are incompatible with AppCenter. In other words the later Unity releases are incompatible with AppCenter. Is there an ETA for a fix and an emergency patch release?

Thank you.

Repro Steps

Please list the steps used to reproduce your issue.

1. Integrate the AppCenter SDK to a fresh Unity project, or use an existing Unity project that has the AppCenter SDK integrated.
2. Use a pre-2022.2.11 Unity version (I used 2022.2.7), invoke a native crash on Android and verify that the crash report appears in the AppCenter dashboard.
3. Update Unity to 2022.2.11 or later (I used 2022.2.19), invoke a native crash on Android and verify that the crash report does not appear in the AppCenter dashboard.

I am pretty sure Unity 2022.2.11 is the exact version that broke it, but I did not explicitly verify this.

I am tagging all the recent employees to get visibility for this.

[Tommigun1980]

It's been a week by now. Is this repo still maintained and if not, please let us know.

I need to reiterate that the latest version of the AppCenter SDK does not work with the latest versions of Unity, and this has been the case for a few months by now.

@Tommigun1980, I appreciate your report and apologize for the delay in response.

We're currently addressing the matter with the team. I assure you, I will provide an update as quickly as possible.

It's been three weeks since your reply. I think there's probably some miscommunication here, what I am trying to say is that the latest version of AppCenter doesn't work with Unity. Unity changed how they wrap native crashes in Unity 2022.2.11, so AppCenter has been broken for the last four months.

This has to be fixed now.

Hi again. When will this get fixed? App Center has not been usable with Unity for the last four months. I was promised a quick update so please get back to me asap.

@Tommigun1980 we will be looking into this issue based on our capacity and priorities which unfortunately can take some time.
Please feel free to contribute a fix if you need it urgently.

What do you mean if I need it urgently? App Center does currently not work with Unity. What could have a higher priority than fixing that? Yeah I do need it to work. If Microsoft can't support App Center anymore then please state that. I don't think it's the customer's responsibility to fix an SDK that doesn't work.

[Tommigun1980]

@lucen-ms Getting back to this again. When do you think this will be fixed? I don't think that asking the customer to fix an SDK that doesn't work is the correct way to operate. And also, please state if Microsoft is not supporting App Center anymore so we can look into alternatives.

Thank you.

[lucen-ms]

@Tommigun1980 App Center is supported by Microsoft. I do not have any ETA for the fix at this moment - I will share it here as soon as I will know it.

Note, we prioritize issue fixes based on number of affected customers - that's why it is not our top priority at this moment. That's why I also suggested you can try to fix it as the code is public - we welcome PRs. Thank you for understanding.

+1 for needing this fixed. This is preventing us from upgrading our Unity version to 2022.3 (Long term support) which we need to do for other fixes

Hello,

this might unblock you, Unity provides a way to fallback to legacy crash handler behavior. https://docs.unity3d.com/2023.2/Documentation/Manual/android-handle-crashes.html

You need add this string to command line passed to Unity:

-androidChainedSignalHandlerBehavior legacy

Hi @todi1856 and thank you very much for the information. We now consider this task as a priority, but there is no ETA yet. I will keep you informed.

Hi @MikhailSuendukov. I think it's been half a year by now that App Center hasn't been working with Unity. When will this be fixed? Goes without saying that people will have to look into alternatives if this won't get fixed soon.

[lucen-ms]

@todi1856 or @Tommigun1980 have you tried the workaround please? Does it work?
