This sub will log the underlying stack trace. It can be useful for debugging cases where the code flow is complex.
In debug mode the underlying stack trace can be incomplete.

B4X:
Sub Log_StackTrace
    Dim lines As List
    #if B4A or B4J
    Dim jo As JavaObject
    lines.Initialize
    Dim stack() As Object = jo.InitializeStatic("java.lang.Thread").RunMethodJO("currentThread", Null).RunMethod("getStackTrace", Null)
    For Each st As JavaObject In stack
        lines.Add(st.RunMethod("getClassName", Null) & ": " & st.RunMethod("getMethodName", Null))
    Next
    #else if B4i
    Dim no As NativeObject
    Dim stack As List = no.Initialize("NSThread").RunMethod("callStackSymbols", Null)
    lines = stack
    #end if
    Log("****************")
    Dim found As Boolean
    For Each line As String In lines
        If found Then
            Log(line)
        Else If line.Contains("log_stacktrace") Then
            found = True
        End If
    Next
End Sub
