This is not ImageDownloader. You made many modifications.

Put a breakpoint in line 89. You will see that your code is wrong.

You should watch the collections video tutorial and see how to correctly use Maps.


Correct code:
Tip 2: don't use ImageDownloader at all. It is not needed since the support for resumable subs. You can simplify your code: [B4X] OkHttpUtils2 with Wait For
Tip 3: remove the two modules and use iHttpUtils2 library instead.

Correct code:

B4X:

Private Sub ShowImgWhenComplete(ilo As imgldrobj,bmp As Bitmap)
   If tasks.ContainsKey(ilo.url) Then
       Dim ti As imgldrobj=tasks.Get(ilo.url)
       LogColor(ilo.url,Colors.Red)
       LogColor(ti.url,Colors.Blue)
       If ti.url=ilo.url Then
           If ti.cache Then
               saveBmpToFile(getkey(ilo.url),bmp)
               completeJobFromCache(ti)
           Else
               completeJobFromNet(ti,bmp)
           End If
       End If
   End If
End Sub

Only in this way photos cached or not?

iHttpUtils2 doesn't cache anything. You will need to cache the images yourself if it is really needed.
