Scalling problem Live wallpaper

[Prosg]

Hello,

I give you my Scalling test app if someone could help.

I explain my problem :

- The pictures are always 720 x 1280 (manga pictures) . One is in Files folder in the project zip

There a lot of devices :
320 x 480
480 x 800
720 x 1280
720 x 1184 (nexus)
800 x 1280

And in this sample app you will see that the live wallpaper not have the complete screen for every devices. (a gray background appear)

Actually for my release app i must do that but the designer is getty crazy xD

Sub img_Click
   
   'Vérife que c'est bien notre wallpaper
   checkCurrentWallpaper

   Dim iv As ImageView
   iv = Sender
   
   Dim tempUrl As String = iv.tag
   Select Case GetDeviceLayoutValues.Width
      Case 320
         tempUrl = tempUrl.Replace("thumb", "images320")
      Case 480
         tempUrl = tempUrl.Replace("thumb", "images480")
      Case 720
         If GetDeviceLayoutValues.Height = 1184 Then
            tempUrl = tempUrl.Replace("thumb", "images7201184")
         Else
            tempUrl = tempUrl.Replace("thumb", "images720")
         End If
      Case 800
         tempUrl = tempUrl.Replace("thumb", "images800")
      Case Else
         tempUrl = tempUrl.Replace("thumb", "images800")
   End Select
   
   Dim realSizeJob As HttpJob
   realSizeJob.Initialize ("realSizeJob", Me, "")
   realSizeJob.Download(tempUrl)
   
End Sub

it's bad coding but the image are well display
