How to Symbolicate an AIR mobile crash report on iOS?

Report · Apr 30, 2013

(I posted this in the wrong forum yesterday, trying here instead.)

I am developing a game that uses the iOS GameKit API via a native extension. It works great over WiFi. But when I switch to Bluetooth, I get intermittent crashes.

So I can start guessing at where my problem lies... but that could take days. iOS is dumping a crash report that it is able to partially symbolicate. (Unfortunately, it's the part that doesn't help me much) For example:

Incident Identifier: B3D0F337-B696-47C9-8ABA-883F2DFA2BA8

So I need to know how to turn those memory addresses into functions. That would help me out a ton. I found a lot of information on how to do it manually via the dSym... but nothing that seems to apply to an AIR mobile app. (And nothing that seems to actually work)

Need a knight in shining geeky armor to rescue me.

Hi,

The information you needed is present @ http://blogs.adobe.com/rajorshi/2011/11/18/debugging-native-extensions-for-air-ios/

I hope it helps!

While the information present at that link is helpful to set up live debugging, (which is great), it doesn't help to symbolicate a crash report. It does, however, have a link to a Stack Overflow question that is directly related... but I've tried the suggestions there and cannot get it to work.

Nevertheless, I did find the source of the problem using other means.
