How to debug the crash log?

[DouglasHennrich]

On firebase's crash log I had this report but how do I know what it means? There's a way to know where to find this problem on the code ?

That looks hard to debug. Do you use kroll- or main-thread? And TiCore or JSCore?

[DouglasHennrich]

Yea I know =/
I'm using main-thread and JSCore

[hansemannn]

Okay, then the core should be fine. In general, it looks like it tries to call a callback which is not allocated anymore, so maybe you fire a global event while closing a Window?

Maybe... I do trigger some backbone's event on window close event. but I guess this happens when I'm on background receiving user's location and saving it on an global array
