Hi, When I use this method print throwable, it prints without stack line number. Any other method could print with line number? or any body can give me some reference? TKS

throwable.printStack()

[kpgalligan]

Is that from ExceptionUtilsJs? It looks like a native stack trace. Not that it matters, but the Js implies it's coming from something else. Anyway...

[kpgalligan]

I'd have to poke around. You can get actual line numbers when you push to Crashlytics, etc. I assume there's a way to do that locally, but I haven't looked into it too much (you can usually figure out what's wrong from function list and debugging, but line number would be nice).

[kpgalligan]

Today is a lot of native code, so I'll keep this in mind while poking around.

@kpgalligan Thanks for clarifying, Actually I hope we could see the crash or stacktrace line number in debug mode just like Java, aHa,Yep, we could figure out the problem from function list and debugging in most time. Thank you for your hot help.
