Event serialization
Event serialization is not supported by processing rules. In the Mobile SDK, you must use a special syntax in the context data parameter to set serialized events directly on the server call.
cdata.put("&&events", "event1:12341234");
For example:
//create a context data dictionary
HashMap cdata = new HashMap<String, Object>();
// add events
cdata.put("&&events", "event1:12341234");
// send the tracking call - use either a trackAction or TrackState call.
// trackAction example:
Analytics.trackAction("action", cdata);
// trackState example:
Analytics.trackState("State Name", cdata);
