Hi all,
What we are trying to do is to send an image via xml.
I'm using the CameraExClass to take a picture (max width 1280) and we encode this to B64 (EncodeBtoS). xML-string is created but after a few pictures the application hangs. the XML-string is null. Any thoughts?
The error which is given:
(Line: 278) If (sXMLFile <>"" AND sXML<>"") Then
java.lang.NullPointerException
