Android Question Error convert list to map

[mrjaw]

I am getting an error when I use map with List

Log("Response from server: " & res)
                Dim parser As JSONParser
                '
                'res=[[17,"clie12345","Chila Perez","-"],[18,"client1235778","Carlos Fuentes","Santiago"]]

                parser.Initialize(res)
                Dim LISTA As List
                LISTA = parser.NextArray 'returns a list with maps
                For i = 0 To LISTA.Size - 1
                    Dim m As Map
                    m = LISTA.Get(i) 'Here this is the error--
                    '========CREANDO UNA LINEA EN LA TABLA VISTA==
                    ID =  m.Get(0) & CRLF & m.Get(1) 'ID record; ID empresa
                    Name = m.Get(2) & CRLF & m.Get(3) 'Nombre y direccion
                    TblClientes.AddRow(Array As String(ID, Name))
                Next

This does not look like JSON? Are you sure the data is JSON?

 

[mrjaw]

Yes.! The problem is when assign the map

 

[DonManfred]

I must agree with @thedesolatesoul Usually a valid json-string contains keyvalue-pairs. A name and a Value. Your json-string seems to have just values.

For example this is such an json i talked about:

{"menu": {"id": "file","value": "File","popup": {"menuitem": [
{"value": "New", "onclick": "CreateNewDoc()"},
{"value": "Open", "onclick": "OpenDoc()"},
{"value": "Close", "onclick": "CloseDoc()"}
]
}
}}

It is a valid json string.

As you can see with this tool: http://basic4ppc.com:51042/json/index.html this json string is made of an array that holds another two arrays. There are no maps here.
