It's a good thing I have lots of hair, because I am ripping them out strand by strand.
I changed my webservice to send me back a json string instead of XML.
My code is very simple
B4X: 
    Dim JSON As JSONParser
        Dim Map1 As Map
        JSON.Initialize(WS_url)
        Map1 = JSON.NextObject
        Dim m As Map
My data string looks like the
B4X: 
[{"Title":"TARGETED","ReceiptTicketItemIndex":166661,"SerialNumber":1,"PerformanceIndex":11206,"TicketCategoryIndex":769,"ReceiptTicketItemIndex1":166661,"ReceiptItemIndex":307226,"CurtainTime":"\/Date(1475197200000)\/","FilmIndex":673,"AuditoriumIndex":19,"TicketCatName":"Senior 62+","TicketCatTypeIndex":4,"AudName":"AUD 7","ScheduleDate":"\/Date(1475128800000)\/","Swapped":null,"SwapReserved":null,"SeatRowNumber":null,"SeatName":null,"RowName":null,"RowScreenToProjection":null,"RowQty":null}]
My error message is on the "NextObject" line, and it states java.lang.RuntimeException: JSON Object expected.

Dim parser As JSONParser
parser.Initialize(<text>) ' Put your text here......
Dim root As List = parser.NextArray
For Each colroot As Map In root
 Dim TicketCatName As String = colroot.Get("TicketCatName")
 Dim ReceiptTicketItemIndex As Int = colroot.Get("ReceiptTicketItemIndex")

Another hint:

If a Json starts with [ it's a list = .nextarray, If it starts with { it's a map = .nextobject

Lists and maps can be combined as you see in your data.
