Android Question Cannot get Wrapper Working - code provided

[Krammig]

Hi,

I am trying to run an app with a third party library, specifically, Chilkat Email Library.

A couple of issues which I cannot seem to find the reason for and was hoping someone could spot what I cannot.

a)
I have built a Wrapper and created a Jar file from a Java file. Code listed below.

b)
I have created a B4A app, code listed below.

ISSUES ;

i)
if I do not have the third party library placed in the ?Files folder I get an error saying it is missing.
However if I place it in there, Chilkat libchilkat.so I see a message in the IDE saying that it is never used.
File libchilkat.co is not used. (Warning #15)

ii)
running the app, it seems to compile and displays input data on the phone. However immediately on pressing the Get button I see the following error.

LogCat connected to: d3ae099

I have checkboxed the Library in the Library Manager.

I would greatly appreciate any assist / feedback / comments on this.

thanks
