App crashes initializing

[fierysquirrel]

Hi,

I'm using the extention in my game (mobile), tested everything, worked well and when I sent to Apple for review, it crashed. The only new thing I added between the previous update and the new one is this extension so I think something is probably happening with it.

The crash log says the following:

At least this is the relevant part where the crash is.

I'm not completely sure but I think the problem is here:

0 GAME 0x000000010070276c alloc_empty_object + 60

with "alloc_empty_object", on the haxe side I'm using this function:

IAP.initialize(IAP_KEY); //For iOS IAP_KEY is ""

which I understand is connected to this file:

ExternalInterface.cpp

which contains the function that is triggering the error.

I'm not really sure about this, that's why I wanted to ask you, in my devices the app doesn't crash but apparently in some devices it's not working.

They tested with an iPad and an iPhone, both with iOS 9.2.

Please if you have a clue or something to fix this bug let me know, I can test and do whatever I have to do to fix it.

I also contacted Apple to request more details about the devices they were using.

Thanks in advance.

I added the whole crash log here in case you want to take a look at it:

@fierysquirrel I took a look above and at the full log. Nothing stands out to me. I'm also not sure this is related to IAP. I don't get how you know that it's tied to IAP.initialize for example. I think your strategy of getting a device where the crash can be reproduced is a great idea.

@thomasuster thank you for your reply, sorry for the delay.

The main reason I believe that the error was triggered by the extension is that is the only new thing I added. Besides this, I think that if you look at the thread that crashed (thread 2) it shows that the last function that was called before crashing was "alloc_empty_object".

Probably I'm not understanding it correctly, I'm not sure.

Anyway, I tested the game in many different devices with same features that Apple mentioned, different OS versions as well and there is no error. I wrote to Apple's team, recompiled, sent the build again and I'm just waiting.

I really think it's a weird crash and was looking for help, didn't know if it happened to you or anyone that has used the extension before.

Still haven't been able to reproduce the error here. Do you think it's better to close the issue or have anything in mind that could probably cause it?

Thank you again for your support.

Try this...

1. Make sure your device has internet
2. Open the app
3. Wait a few seconds (so the IAP has a chance to connect successfully)
4. Disable your mobile internet
5. Try to make a purchase

If it crashes, then my PR that's waiting review might fix it.

Hi,

I think this is not the issue, this is fine.

I'm still waiting for Apple's response on the game's review, once I know I will let you know but once again, we tested many times in different devices and everything went well. There is an issue if you try to make a purchase twice in a row but that can be fixed in my code, I guess you don't need to do anything.

Once again thank you for the support, will keep you updated.
