Android Question Stack Trace <> Error log

[MitchBu]

I am trying to implement the uncaught error reporting as described in https://www.b4x.com/android/forum/threads/59805/#content

As it stands, the log is pretty cryptic, since it does not contain any reference to the B4A source.

Would it be possible instead to get the error as reported in the log pane of the IDE ?

Here, I see where the error occurred in my B4A code. THat is a whole lot easier to figure where the problem is:

Why work hard? Use Crashlytics.

The two stack traces are quite similar. The error happened in Starter.Application_Error. Looks like you haven't initialized the StringBuilder.

Thank you Erel
