Awesome project, however i'm playing around with it and sending the following lines of code and i keep getting an error.

Any ideas why that is and how to get this to work, the reason i'm testing it with the argparse modile is because the scripts i have depend on the argparse module and was hoping i could port this project over to android.

the lines of code i'am sending are the following.

Sub argpasrser As String
    Dim str As StringBuilder
    str.Initialize
    str.Append("import sys").Append(CRLF).Append("import argparse").Append(CRLF) _
    .Append("parser = argparse.ArgumentParser()").Append(CRLF) _
    .Append("parser.add_argument(" & """echo""" & ", help="&"""echo the string you use here"""&")").Append(CRLF) _
    .Append("args = parser.parse_args()").Append(CRLF)  _
    .Append("print args.echo")
    Log("command: " & str.ToString)
    Return str.ToString
End Sub

I'am calling this function which returns the formatted string to the

Py.Execute(argpasrser)

but i keep getting the following error:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **

Thanks, i'm hoping i can find the solution to this so i can proceed and hopefully port this project and load it onto a raspberry pi running Android Things.

Regards,
Walter
