Have you tried to use ImageDownloader: http://www.b4x.com/forum/showthread.php?p=179505

Thanks a lot .
No I was trying to accomplish a similar result by clearing an array of bitmaps
And I checked with IsPaused() before calling the function that sets images to imageviews.
I will check ImageDownloader as soon as possible .
Thanks again

Hello again.
I used ImageDownloader and it was really great but now I noticed it has this issue although it shouldn't but anyway the problem happens when I enter one category and quickly get back to the first Activity and the choose another category.
When I do this the old images get downloaded instead of the new ones .
How can I fix this?

Not sure that I understand. Can you upload your project (File - Export as zip)?

I am sorry I am developing it for someone else but I will try to make it clearer

I have main activity with some categories when I click one of them I start the second activity and pass links to ImageDownloader to show them on the second activity

If I for example chose category "A" then I pressed back button which will call "ActivityIsPaused" and chose category "B" I would get "A" images.
I hope it is clear now

Are you sure that you are filling the links map correctly?

I think so .

I am putting imageviews and links to map in a for loop

B4X:

imgviewsmap.Put(imv,url.Get(i))

and then I pass the map to download Sub

B4X:

CallSubDelayed2(Imagedownloader, "Download",imgviewsmap )

Add some Log messages to make sure that the Map is filled correctly. Also make sure to call:

B4X:

Sub Activity_Pause (UserClosed As Boolean)
   CallSub(ImageDownloader, "ActivityIsPaused")
End Sub

I am using it like this

B4X:

If UserClosed = True Then
     CallSub(ImageDownloader, "ActivityIsPaused") 
End If

After using some log statements here and there now I believe that this call is delayed

B4X:

CallSubDelayed2(Imagedownloader, "Download",imgviewsmap )

When I get back to main activity and then to the second download sub of Imagedownloader gets executed twice
But if replace CallSubDelayed2 with CallSub2 , images never gets downloaded

It is hard to say without seeing the full project. You can try to reproduce it in a smaller project and upload it.

edit :That did not help

By the way would DoEvents be our problem? because I added it at loops in imagedownloader service

I don't think that DoEvents is related to this issue. If it is simple to reproduce then you can send me your project to erel@basic4ppc.com and I'll try it.

I think my problem happens because the ImageDownloader finds the same imageviews

B4X:

Dim imv as ImageView

Seems to have always the same android.widget.ImageView{42b9f158... reference
When image gets downloaded and the user is back to the second activity, ImageDownloader find the same key of imagviews,links and sets their bitmaps

I hope my post is clear
