iOS Question ImageDownloader

[MarcoRome]

Hi, i have this code:

Dim m As Map
                    m.Initialize
                    m.Put(ImageView1, "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria"))
                    Downloader.Download(m)

In this way i have this message:

Error downloading image: https://www.devil-app.eu/devil-app.eu/pizzerie/<null>

if i write the code so:

Dim foto As String = "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria")
                  
                    Dim m As Map
                    m.Initialize
                    m.Put(ImageView1, foto)
                    Downloader.Download(m)

work.
I dont understand why

What is the output of Log("m: " & m.Get("logo_pizzeria"))?

Based on the error message there is no such item in the map.

I wrote that in this mode:

Dim foto As String = "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria")
                  
                    Dim m As Map
                    m.Initialize
                    m.Put(ImageView1, foto)
                    Downloader.Download(m)

Work.

Don work if i use this code:

 m.Put(ImageView1, "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria"))

I don't understand your code. m.Get("logo_pizzeria") will return Null for sure as you just initialized the map. Why are you doing it?

 

[MarcoRome]

This isnt null. I copy only a part code. For sure m.Get("logo_pizzeria") have a value infact... if i put the value in variable (foto) work:

Dim foto As String = "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria")

Dim m As Map
m.Initialize
m.Put(ImageView1, foto)
Downloader.Download(m)

but if i assign the variable in direct mode no.

m.Put(ImageView1, "https://www.devil-app.eu/xxxxxxx/pizzerie/"& m.Get("logo_pizzeria"))

The m.Get("logo_pizzeria") have value by a select

ExecuteRemoteQuery($"Select logo_pizzeria from pizzeria_xxxx where id_utente = ${Main.id_pizzeria}"$,"CaricoLogo")

....JobDone

        Case "CaricoLogo"
                Dim VERIFICA As List
                Dim m As Map
                m.Initialize
                VERIFICA = parser.NextArray 'returns a list with maps
                If VERIFICA.Size > 0 Then
                    m = VERIFICA.Get(0)
                    Dim foto As String = "https://www.devil-app.eu/devil-app.eu/pizzerie/"& m.Get("logo_pizzeria")
                   
                    Dim m As Map
                    m.Initialize
                    'm.Put(ImageView1, "https://www.devil-app.eu/devil-app.eu/pizzerie/"& m.Get("logo_pizzeria"))
                    m.Put(ImageView1, foto)
                    Downloader.Download(m)

It will always be null in the code from the first post. You can also see the null string in the logs. I cannot guess what the code that you haven't posted is doing.

Check the value of foto.
