iOS crashes for 25% of users. (Android is fine) #610

Closed unnanego closed 4 years ago

unnanego commented 4 years ago

Approximately 25% of all my apps users (both this one and I'm guessing I had the same problem with my previous app from last summer, but crashlytics doesn't go that far) experience crashes on iOS only (this is a unity project, Android has no crashes at all). Crashlytics gives me the following stack trace and some of the crashes have this key: CoreUI: deallocating _CUIInternalLinkRendition 205 /System/Library/CoreServices/CoreGlyphs.bundle/Assets.car

Here's the stacktrace from Crashlytics: 0 UnityFramework UnityAdsEngineSetDidFinishCallback + 27372 1 UnityFramework Firebase_App_FutureVoid_SWIGUpcast + 14940256

full: https://pastebin.com/f5vYT5WB

Unity 2019.3.3 Latest xcode and iOS versions. Unity Firebase SDK 6.11.0

I can't reproduce the error on any of my devices.

There's a topic on stackoverflow https://stackoverflow.com/questions/59717173/crash-info-entry-0-coreui-deallocating-cuiinternallinkrendition-assets-ca but it has no answer

This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @unnanego,

Without a reproducible case, unfortunately not sure what this issue might be, as we haven't seen anything similar. My best guess would be that maybe your FirebaseApp is being garbage collected, if you aren't holding a reference to it. If you can, please try to track down a case that can reproduce this.

Hey @unnanego. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Since there haven't been any recent updates here, I am going to close this issue.

@unnanego if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

We have exactly the same issue. iOS only, Unity 2019.3, last Firebase SDK. Did you solve the issue @unnanego? Right now it still is quite a mystery to us...

patm1987 commented 4 years ago

Hi VGMFR/unnanego,

I'm re-opening since there has been some additional follow up. We really really need repro steps if we're going to help solve this issue. I know that not being able to repro on your own devices is going to make this more challenging too.

Some things to help, make sure all of these fields from the template are filled in (I know this came over from another github repo, so I apologize for asking this after the fact)

Unity editor version: 2019.3.3 Firebase Unity SDK version: 6.11.0 Source you installed the SDK (.unitypackage or Unity Package Manager): Firebase plugins in use (Auth, Database, etc.): Additional SDKs you are using (Facebook, AdMob, etc.): Platform you are using the Unity editor on (Mac, Windows, or Linux): Platform you are targeting (iOS, Android, and/or desktop): Scripting Runtime (Mono, and/or IL2CPP):

I can also say that one of the first debugging steps will be to have you upgrade to the latest SDK version - which is currently 6.13.0.

For reproduction, we prefer if at all possible you can reproduce on the quickstart (here's the Crashlytics one, since that's the SDK you mention currently).

Without seeing your code and without solid repro steps, it's hard to say exactly what's happening (and therefore to get any sort of fix in). I do notice that there are some Unity Ads callbacks in the callstack. It might be worth auditing scripts where you call Show with a finishCallback and see if there's any way that that may be triggered after that script or the game has been torn down. I don't know the best practices around that API, but it might be as simple as checking if this is not null in your callback methods (given Unity's object model).

I hope that helps!

Hi Patrick,

Thanks for reopening this. We still can't reproduce this issue on our side, even if I am struggling with it since last Thursday. Here is the information that I can give you:

Unity editor version: 2019.3.6f1 Firebase Unity SDK version: 6.13.0 Source you installed the SDK: Unity Package Manager Firebase plugins in use: Crashlytics & Analytics Additional SDKs you are using: Facebook, Ogury, Appsflyer for the biggest ones Platform you are using the Unity editor on: Mac Platform you are targeting: iOS and Android. As said, Android works flawlessly, this problem only occurs on iOS. Scripting Runtime : IL2CPP, .Net 4.x

Hope it helps! I'll come back if I get more info.

Hello, this is the first search result on google when you search UnityAdsEngineSetDidFinishCallback and I'm not sure if the crash is somehow related to Firebase but I'm writing my findings about this issue. Firstly:

Unity editor version: 2019.3.7 2019.3.8 2019.3.9 (happens on all of them) AND 2018.4.5 Firebase Unity SDK version: 6.13.0 Source you installed the SDK: .unitypackage Firebase plugins in use: Crashlytics, Analytics, RemoteConfig, CloudMessaging Additional SDKs you are using: MoPub (latest, 5.12), Facebook, AdMob and a lot of ad network SDKs Platform you are using the Unity editor on: Mac Platform you are targeting: iOS Scripting Runtime: il2cpp, .net 4.x

So we have about 110k crashes on Crashlytics and 100% are background and iOS 13. There are several crashes that all have similar call stacks. They all have [UIApplication _terminateWithStatus:] or UnityAdsEngineSetDidFinishCallback. So it somehow crashes when you force-kill the app by swiping the home button/bar then swiping the app up to kill. Then a crash popup appears saying the app crashed.

At first we thought that this is a 2019.3 crash but then we got the same behaviour crash (force-kill) on Unity 2018.4.5, that led me to think that this isnt a Unity version thing and some SDKs are at fault. Weird thing is that we have another game with Unity 2019.2.14 and with same version SDKs and these crashes dont happen there.

When we force-kill the app as described above while watching an ad, it crashes like %80 of the time. Note that which ad network is showing the ad does not matter, I've had the crash happen on Facebook, AdMob, Unity etc so this makes me think that it could be MoPub related.

Currently I have no reason to believe that this crash is related to Firebase. I'll post updates if I find anything else.

Here are some stack traces from 2 different apps on iOS:

@arkenthera Thanks for investigation this issue too. Turns out that we have the same issue (with 100% background) that you have. But I also have a crash that seems to be on launch with a different stacktrace and that seems to be related somehow:

@unnanego @arkenthera @VGMFR I've been struggling to find the cause of the similar crash for couple of days now. This thread is almost everything you can find at all. So maybe my findings would be helpful to you guys.

The crash stack trace symbolycation is "corrupted" because firebase lacks symbols to process the addresses. If you look closely at symbolicated output you'll notice the offsets from base function addresses are huge (MetalHeap::AliasResources() + 76544 or _operator delete[](void*, std::nothrowt const&) + 1421404) which makes no sense at all: no function is that large. Probably firebase tries its best to symbolicate the addresses with not much luck. I checked on crashlytics page and yes, some symbols are missing for the build (marked as Optional for some reason).

The reason for that is Unity changed the way xcode projects are structured starting from 19.3. It now separates the application from unityframework, and when built they produce separate dSYM files. Firebase only upload one of them: I believe this is a bug in Unity Firebase Crashlytics implementation. So when I uploaded symbols manually, new strack traces of the same bug started to look more to the point, from the

The crash is actually 100% reproducible, unity app just crashes when user closes it while some ad is running. When UnityAppController.UnityCleanupTrampoline() gets called it then sets root ViewController to nil, but this lead to iOS 13 asking the app for application:supportedInterfaceOrientationsForWindow, which then asks ViewController for orientations. This leads to crash in backgound, because app is "closed" already. You can check out "Data\PlaybackEngines\iOSSupport\Trampoline\Classes" folder at Unity install location to have a look at sources yourself. This is clearly a Unity bug. I've tried to quickfix it by changing the UnityCleanupTrampoline, with no luck. The crash still reproduces, but not shown in crashlytics at all for some weird reason.

Please let me know if you find any solution to this. Thanks.

Hey, @L4fter thanks for sharing your findings. We opted to downgrade to Unity 2019.2.x in one game and the crashes went away. But we cant downgrade some other game because it depends on some 2019.3 features. I'm discarding what I said about Unity 2018 in my previous post because that must be something else. We didnt experience this crash when we downgraded 1 game to 2019.2.x , and with your findings it's certain that this is a bug in 2019.3.x.

I also tested this in Unity 2020 beta and it's happening there too.

@L4fter Thanks a lot for sharing this. You should report this bug to Unity using Unity Bug Report!

L4fter commented 4 years ago

@VGMFR I did. Will get in touch if I receive any news. Another question is: should the bug in crashlytics regarding unity 19.3 be opened separatly from this thread? @patm1987 ?

How destructive would removing UnityCleanupTrampoline() from applicationWillTerminate be? I'm comparing Unity 2019.2.x and 2019.3.x applicationWillTerminate callbacks in UnityAppController.mm, obviously a lot are different but if I change the code to be same as 2019.2.x implementation, crash does not happen.

This means:

2019.2.x:

- (void)applicationWillTerminate:(UIApplication*)application
{
    ::printf("-> applicationWillTerminate()\n");

    Profiler_UninitProfiler();

    if (_unityAppReady)
    {
        UnityCleanup();
    }

    extern void SensorsCleanup();
    SensorsCleanup();
}

2019.3.x vanilla:

- (void)applicationWillTerminate:(UIApplication*)application
{
    ::printf("-> applicationWillTerminate()\n");

    // Only clean up if Unity has finished initializing, else the clean up process will crash,
    // this happens if the app is force closed immediately after opening it.
    if (_unityAppReady)
    {
        UnityCleanup();
        UnityCleanupTrampoline();
    }
}

2019.3.x edited:

- (void)applicationWillTerminate:(UIApplication*)application
{
    ::printf("-> applicationWillTerminate()\n");

    Profiler_UninitProfiler();

    // Only clean up if Unity has finished initializing, else the clean up process will crash,
    // this happens if the app is force closed immediately after opening it.
    if (_unityAppReady)
    {
        UnityCleanup();
        SensorsCleanup();
    }
}

If I run the app like this, the crash does not occur. But I dont know the extents of what could happen by removing the trampoline cleanup code. We can test this in production but if anyone has any ideas of what could happen by changing the code like this I'd appreciate it.

L4fter commented 4 years ago

My bet was to create flag like "shutdownStarted", set it first in UnityCleanupTrampoline(), and then check if it is set inside supportedInterfaceOrientationsForWindow. The latter already have a similar check in both unity versions:

if ([window rootViewController] == nil)
        return UIInterfaceOrientationMaskAll;

This failed, dunno why, probably a simple if-else in obj-c is just to much for me.

But you there have a great solution to use before official fix. The application is already closing, so who cares if anything breaks as long as no crash is happening.

0x61726b commented 4 years ago

We released a build with the edited applicationWillTerminate code and all the crashes went away and currently sitting at %99 crash free.

zoranigic commented 4 years ago

Cause of error is [_UnityAppController window].rootViewController = nil; Commenting it prevent error from happening.

`extern "C" void UnityCleanupTrampoline() { // Unity view and viewController will not necessary be destroyed right after this function execution. // We need to ensure that these objects will not receive any callbacks from system during that time. //[_UnityAppController window].rootViewController = nil; [[_UnityAppController unityView] removeFromSuperview];

// Prevent multiple cleanups
if (_UnityAppController == nil)
    return;

[KeyboardDelegate Destroy];

SensorsCleanup();

Profiler_UninitProfiler();

[DisplayManager Destroy];

UnityDestroyDisplayLink();

_UnityAppController = nil;

}`

odysoftware commented 4 years ago

At least I can confirm that with Unity 2019.3.1f6 you should not have those issues, but when moving up to at least 2019.3.1f9 then having several native crashes in analytics starts! - So for now downgrading to 2019.31f6 should work.

So the error must be in one of the versions after f6

VGMFR commented 4 years ago

@L4fter Hi, did you get some news from Unity? I also reported this issue, and even with the complete reproduction description, they ask for a project where they can just reproduce it without any effort. I'll try to do this, but I don't have the time at the moment. What is your status on the subject? Thanks!

0x61726b commented 4 years ago

@VGMFR I submitted a report with a project attached and repro steps last week. Havent heard back

L4fter commented 4 years ago

@VGMFR not a single word from them image

L4fter commented 4 years ago

@arkenthera @VGMFR I created thread at Unity forum to bring more attention to the bug from Unity team https://forum.unity.com/threads/unity-2019-3-crashes-on-ios-13.880030/ I assume they will notice the issue faster this way. I hope you guys can put a comment there describing the issue and linking your own bug reports. Hopefully that will give this thing a little momentum.

Hey @unnanego. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

odysoftware commented 4 years ago

Its still present -> crashes in UnityIsOrientationEnabled - is not related to unity ads! I have it in my app and its always crashing on closing the app - now also tested on 2019.3.13f1

cgviver commented 4 years ago

i faced the same issue in Unity 2018.4.21f1 plugins used : Admod, FB audience network etc .

How i resolved :

Previously :

changed to :

}

its working fine now without any crash while close and reopen while i build it directly to my iPad but after uploading to test flight i am facing the same issue.

and edited :

but still facing the same crash issue. Any help will be appreciated.

VGMFR commented 4 years ago

@arkenthera @L4fter Thank you for your answers. No need to send them a project then, si you already did it. In the meantime we applied @arkenthera fix and it worked: no more crashes reported on the subject!

apautrot commented 4 years ago

On my side, until a fix is found on Unity side, I SOLVED THIS ISSUE by applying the fix proposal made by @zoranigic and my build is live since 2 days, with more than 2K users acquired, ans so far, not a single crash (while my previous version had 5% users crashing on this issue).

Since there haven't been any recent updates here, I am going to close this issue.

@unnanego if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

0x61726b commented 4 years ago

Unity QA team finally answered my bug report saying they reproduced the crash and will resolve it in the future releases

nicolasgramlich commented 4 years ago

Just experienced the same issue. Thanks for being persistent @arkenthera :)

trymoto commented 4 years ago

@arkenthera also thanks! Ran into the crash problem today while building on 2019.3f14, rolled back to 3f9. Hoping to see it fixed in the upcoming changelogs.

Alej-P commented 4 years ago

@arkenthera do you have a link to the Unity issue tracker page?

renattou commented 4 years ago

I talked with Unity support and it seems the fix was shipped with Unity 2019.4.0f1. We still didn't try updating though.
