Lots of crashes on end user devices

Hi,

We are seeing lots of crashes on our end user devices. Our current release was built with 5.3.1.

Any ideas what could be causing this?

Thanks.





And this is another crash:

 

Hi @christophergoy ,

This is not happening in our development environment.. this is happening to about 5% of our live users. We are getting these crash reports from Crashalytics.

These are full stack traces.

and ...

 

Hey @christophergoy, that's cool that one of the crashes will be fixed in the next patch.. will hold the next app update for now.

About the second crash.. I can't reproduce it in house... we are just getting the reports from the field.. I'll let you know if I get any more info.

Thanks!

 

Is this supposed to be fixed in Unity 5.3.3f1? We're still seeing the following two crashes related to Repaint and sending the app to the background on iOS.

Any suggestions on what is causing this? This is on devices with iOS 9.2

 

Hi @christophergoy

We currently modify keyboard.mm in a postbuild script to get a round a few issues (removing the shortcut bar introduced iniOS9 and stopping auto capitalization because weird things were happening in NGUI). The modifications we do are as follows:

Code (CSharp):

1. // Modify the file Keyboard.mm to remove the new iOS9 keyboard shortcut bar
2.             string textViewCodeToInsert =
3.                 "\n\n" +
4.                 "    if ([textView respondsToSelector:@selector(inputAssistantItem)]) {\n" +
5.                 "        UITextInputAssistantItem *inputAssistantItem = [textView inputAssistantItem];\n" +
6.                 "        inputAssistantItem.leadingBarButtonGroups = @[];\n" +
7.                 "        inputAssistantItem.trailingBarButtonGroups = @[];\n" +
8.                 "    }\n";
9.             InsertCodeAfter(path + PATH_KEYBOARD_FILE, "textView.text = initialText;", textViewCodeToInsert, "TextView: Removing keyboard shortcut bar");
10.  
11.             string textFieldCodeToInsert =
12.                 "\n\n" +
13.                 "    if ([textField respondsToSelector:@selector(inputAssistantItem)]) {\n" +
14.                 "        UITextInputAssistantItem *inputAssistantItem = [textField inputAssistantItem];\n" +
15.                 "        inputAssistantItem.leadingBarButtonGroups = @[];\n" +
16.                 "        inputAssistantItem.trailingBarButtonGroups = @[];\n" +
17.                 "    }\n";
18.             InsertCodeAfter(path + PATH_KEYBOARD_FILE, "textField.text = initialText;", textFieldCodeToInsert, "TextField: Removing keyboard shortcut bar");
19.        
20.             // Turn off "UITextAutocapitalizationTypeSentences" because it causes flickering backspace/shift keys when the input is hidden
21.             // This is something to do with how Unity & NGUI deal with input.
22.             // http://www.tasharen.com/forum/index.php?topic=9960.msg47765#msg47765
23.             // https://feedback.unity3d.com/suggestions/touchscreenkeyboard-auto-capitalization-support
24.             // The acceptable workaround seems to be to disable 'UITextAutocapitalizationTypeSentences'
25.             ReplaceCode(path + PATH_KEYBOARD_FILE, "UITextAutocapitalizationType capitalization = UITextAutocapitalizationTypeSentences;", "UITextAutocapitalizationType capitalization = UITextAutocapitalizationTypeNone;", "Keyboard: Disabling UITextAutocapitalizationTypeSentences because of the flickering key issue found when pressing backspace and the input is hidden");
26.  

I'll attach our keyboard.mm from our current build (deployed with 5.3.3p2).

Is your previous fix present in our current keyboard.mm? (had to add a .txt extension so I could attach it)

 

Oh you want the version from the trampoline folder. Ah ok. See attachment:

Thanks

 

I have also been getting a lot of these crashes below reported from players on iOS, mainly iPhone. I'm running Unity 5.3.2f1.

@christophergoy -- Thank you for that suggestion, I am updating now.

 

In Unity 5.4.3p3 the bug is still present. Are there any ideas how to fix it without waiting for a new patch version?

 

If this is the same one, I have a partial fix for it. Our "UnityRepaint()" crashes dropped by about 60-70% following this. You need to attache this to any monobehaviour class you are sure is always present in your app.

Code (CSharp):

1. #if UNITY_IOS && !UNITY_EDITOR
2.     IEnumerator OnApplicationFocus(bool hasFocus)
3.     {
4.         if ( !hasFocus )
5.         {
6.             Application.targetFrameRate = 30;
7.         }
8.         else
9.         {
10.             yield return null;
11.  
12.             Application.targetFrameRate = 60;
13.         }
14.  
15.     }
16. #endif

 

We're also seeing the FrontBoardServices crash on end user devices. This is in builds created with 5.5.0.

 

I'm having this issue on my game, and it is stopping me from getting an update out on iOS now. The Apple review team keep failing me due to this crash.

Does anyone have any updates on this? I've tried going to Unity 2018.2.12f1 and still no luck.

I'm going to try this, see if it helps. Thanks

 

i also having this issue on my game, it happened on ios 12. only on ios 12 happend . did you sloved the question?

 

Hi buddy,

Yes, I did manage to get my app past Apple review.

I tried changing two things from the iOS player settings window -

• Turned the Multithread rendering tick box option to off (unticked it), and
• I changed the Script optimization from "Fast" to "Safe and Slow".

This seemed to stop the crashing, and Apple finally made my app available on iOS.
Do you want to try that and see how you go?

Cheers
Navil

 

Is there anyone could explain why Multithread rendering and Script optimization may cause this issue?
