hi
i had made a program that loads about 200 items in a custom listview
in item 189 it crashes and give out of memory error

i had already used loadsample

B4X: 
imv.Bitmap = LoadBitmapSample(File.DirInternalCache,AsyncDownloader.FileName,640,360)

my device is galaxy s6 edge, which is very powerfull, why did it crashed in less than 200 images ?

is there is a way to load the images only when i scroll to them ?

(It should be 640dip, 360dip)

You can ask the OS to give you more memory by adding this line to the manifest editor:
B4X: 
SetApplicationAttribute(android:largeHeap, "true")

A better solution is to only load the images that are currently visible. Add more images when the user scrolls the list and remove non-visible images.
