Duplicate class Error thrown with ShortMessage library on Android mode

I’m running Processing v3.5.4 on Windows10. I’ve downloaded the package from:
C:\Users\home\Documents\Processing\libraries\ShortMessage
I added the library ShortMessage from the default list. I can run the sample code ReceiveMessages.pde in java mode without errors.

When I run it on Android mode I’m getting:

     Duplicate class org.ajwcc.pduUtils.gsm3040.SmsSubmitPdu found in modules jetified-pduutils (pduutils.jar) and jetified-smslib-3.5.1 (smslib-3.5.1.jar)
     Duplicate class org.ajwcc.pduUtils.gsm3040.ie.ConcatInformationElement found in modules jetified-pduutils (pduutils.jar) and jetified-smslib-3.5.1 (smslib-3.5.1.jar)
     Duplicate class org.ajwcc.pduUtils.gsm3040.ie.InformationElement found in modules jetified-pduutils (pduutils.jar) and jetified-smslib-3.5.1 (smslib-3.5.1.jar)

How can I fix this?
