B4J Question HttpJob: sequential or simultaneous download? (Noob Question!)

[javieret]

Hi. I'm writting an app which has to download 30 pictures, all of them of the same size.
i have 2 options:
1) use 1 httpjob and download them sequentially
2) declare 30 httpjobs and download all of them simultaneously.

I think its obvious that (1) is the best approach, right? Less memory use, less open connections... i'm new into b4j and also a noob at coding!

No. I would have started with the second option. Your PC can handle many concurrent network connections.
Note that if the images are downloaded from the same domain then OkHttp will throttle them internally.

Thanks, Erel! I've tried (2) and... it worked like a charm! BTW I've learnt a lot about this subject from this post of yours which contains the Imagedownloader example: https://www.b4x.com/android/forum/threads/customized-listview.34951/#content
