Parsing your apps logs

It is possible to access your apps logs with LogCat from the Phone library. Note that it doesn't require any permission however you cannot use it to read the logs of other apps. The LogCatData event is raised on a different thread. This makes it a bit more difficult to work with this event if...

The only way I know of to get a stack trace is to catch an Exception and use the ExceptionEx object in my Threading library | B4X Programming Forum

    Dim Ex As ExceptionEx
    Ex = LastException

You can also use it to Throw your own Exception if needed.

This will work in B4A and B4J, it will log the underlying Java stack:

Sub LogStackTrace
    Dim jo As JavaObject
    Dim stack() As Object = jo.InitializeStatic("java.lang.Thread").RunMethodJO("currentThread", Null).RunMethod("getStackTrace", Null)
    For Each st As JavaObject In stack
        Log(st.RunMethod("getClassName", Null) & ": " & st.RunMethod("getMethodName", Null))
    Next
End Sub

It will make more sense in release mode.

thanks Manfred
i don't access to log but simply i need to know what is sub tha have called a second sub from second sub
for example
i have a pubblic sub named Log_generic that is called some times.
From this sub i need to know who have called it without pass subFrom parameter if possible.

sub s1
msgbox("first sub","")
log_Generic("s1","detail of log..")
end sub

sub log_Generic(subFrom as String, LogData as String)
'i need here to know subFrom without pass the parameter if possible

LOG($"
  Procedure:  ${subFrom}
  Detail:     ${logData}
"$)

end sub
