Android Question Strange JSONParser behaviour

[Descartex]

Hi.
I'm working with JSON strings that a webservice sends to my app, but it crashes with a strange behaviour.
If I do this:

Log(JSONParser.NextArray.Size)
                Dim l As List
                l=JSONParser.NextArray

On the log it puts this:

Spoiler: Log

2
Error occurred on line: 156 (Main)

It means that the list returned by NextArray has 2 elements, but it crashes when I try to assign to a list to handle it.
I've tried the online tool to check the string is right and it seems yes...

Can someone bring some light on this?
Thank you in advance.

Probaste algo como esto

Sub ObtieneTiposEventos
    Dim j As HttpJob
    j.Initialize("", Me) 'name is empty as it is no longer needed
    j.download2(ModConn.Url_php_mysql("TPEVENTOS"), Array As String ("REQUEST_METHOD", "GET_TPEVENTOS", "USER_ID", ModConn.IMEI.GetDeviceId))
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        'The result is a json string. We parse it and log the fields.
        Dim jp As JSONParser
        jp.Initialize(j.GetString)
        Dim quotes As List = jp.NextArray
        For Each quot As Map In quotes
            Log(quot.Get("j1"))
        Next
    End If
    'j.Release

End Sub

It's strange, if I access the items just after initialize the parser it works, but if i make some access to the parser, for example, to its size, it crashes.
It can be possible it "unloads" it after the first access?

Thanks anyway, @rscheel .

Log(JSONParser.NextArray.Size)

This code parses the complete string returns the list and prints its size.
You must initialize JSONParser again.
Or change your code to:

Dim items As List = JSONParser.NextArray
Log(items.Size)
'work with items
