Android Question What is proper way to handle 1000+ HD images?

[Pendrush]

I want to make app similar to this.
I know how to make everything, but don't know proper way to handle 1000+ HD images without triggering Out Of Memory error.
Can anyone recommend way how to load and release images by releasing memory they occupied?

You can also easily resize a bitmap once you have loaded it.

I know for that, but problem is even when you resize image. Loading 1000+ or 5000+ will trigger OOM even images is not HD or they are resized. I can see in Android Monitor how app use more and more memory for every new loaded image in same ImageView.

 

[Peter Simpson]

Well you can just optimise the images before saving them then load them up resizes, you will not get any out of memory issues then.

What size are the saved images?

Loading different image in same ImageView leave reference "live" from previous loaded image. As I continue to load different image in same ImageView, memory consumption start to grow as reference for every loaded image is still "live". I need a way to "break" reference from previous loaded image in that particular ImageView.

The question is, has your application died because of too many images? What makes you think that the image is "live". Java and most likely Android's Dalvik/ART are lazy in collecting garbage (only doing it when forced to).

Ignore the above, I really need to read better

I know for that, but problem is even when you resize image. Loading 1000+ or 5000+ will trigger OOM even images is not HD or they are resized.

why would you load 1000 images at once?

Loading different image in same ImageView leave reference "live" from previous loaded image.

do you have an example how you doing this?

do you have an example how you doing this?

See Erel's example here, using the xCustomListView you can load many images but, the trick there is that it will only load the images within the Visible Range, this speeds loading images tremendously and at the same time it saves resources, this will help in your situation.

Problem is in the Map (as it get larger and larger), totally unrelated with my first suspicions.
So it's coding error, nothing related with images.
