Android Question MultiThread

[kkkpe]

I have to load with httputils2 a spinner with many data records. how can I run a multithreaded? Can I use the library Treading? there is a better solution for multi-threaded?

HttpUtils2 handles the request in the background. So it doesn't slow down your app. Can you post your JobDone code?

Sub JobDone(risp As HttpJob)
    If risp.Success Then
        Dim dati As String
        Dim jsondati As JSONParser
        Dim listadati As List
        Dim m As Map
       
        If(risp.JobName="ricevidati") Then
            dati=risp.GetString
            jsondati.Initialize(dati)
            listadati=jsondati.NextArray
            'Spinner1.Add("")
            ACSpinner1.Add("")
            For i=0 To listadati.Size-1
                m=listadati.Get(i)
                'Spinner1.Add(m.Get("descrizione"))
                ACSpinner1.Add(m.Get("descrizione"))
                mdati.Put(m.Get("descrizione"),m.Get("codice"))
            Next
        else If(risp.JobName="inviocoord")Then   
            Try
                dati=risp.GetString
                jsondati.Initialize(dati)
                m=jsondati.NextObject
                If(m.Get("risposta")="ok")Then
                    Msgbox("COORDINATE REGISTRATE","MESSAGGIO")
                End If       
            Catch
                Msgbox(LastException,"MESSAGGIO")
            End Try
           
        End If
    End If
    risp.Release
End Sub

Is the json file very large? Have you tested it in release mode?

Thanks Erel have answered you directly. For me this is an honor.
I'll do the tests and let you know.
I would like to ask you how I can manage the multithread with B4A.

You can use the Threading library to run code in the background. However in most cases it is not needed and will make your program much more complicated. There are also things that you cannot do in the background. For example you cannot add items to the spinner in the background as it is a UI element.
