Android Question Halt on Json.Parse NextArray

how does the json you want to parse look like?
Without it is is hard to answer your question...

Add Log(res) to print the response string.

Dim j As HttpJob
j.Initialize("", Me) 'name is empty as it is no longer needed
j.Download("https://embalagenscanada.com.br/api/Prod/2/1")

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 msg As String
msg = j.GetString.Replace(Chr(92) & Chr(34) ,Chr(34))
xui.MsgboxAsync(msg, "Sucesso")
'equivalent to:
Dim jp As JSONParser
jp.Initialize(msg)
Dim lst As List = jp.NextArray
' For Each col As Map In lst
' Dim A As String = col.Get("A")
' Dim P1 As Double = col.Get("P1")
' Dim B As String = col.Get("B")
' Dim P2 As Double = col.Get("P2")
' Dim C As String = col.Get("C")
' Dim E As Double = col.Get("E")
' Dim F As Double = col.Get("F")
' Dim G As String = col.Get("G")
' Next

Else
xui.MsgboxAsync(j.ErrorMessage, "Embalagens Canada")
End If
j.Release
ERROR EM Nextarray , close app

The API returns an XML with a structure of a String JSON variable.

You should check the API return parses.
