Hi Nataliya,
Did you ever get an answer?
We don't have any code samples for XEVENT beyond those in Cary's blog.
I believe XEVENT doesn't work on all Android versions, and XEVENT is now viewed as an out-going technology on our products that may not be supported in future.
We are working on new Android SDKs going forward - is this something that would be of interest to you?
Thanks,
Lewis.
