Android Question Simple question about recycle imageview

[Douglas Farias]

Hi all.
I tried a few things about recycling here in the forum but nothing very clear and explained.

what is the right way to use multiple images in a ImageView?

for example
i want to show a imageview where i will load around 50+ images with size 600x600 or more.

1 - the recycle its the correct function on this case?

What should I do to load all those images without memory crash or any other type of crash?

as I think it is
- Open app
- Show image on imageview
- Use recycle to clear the image
- show another image on imageview
- Use recycle to clear the image
- show another image on imageview
- Use recycle to clear the image
- show another image on imageview
.....

2 - this is correct to avoid crash?


3 - what the exacty time i need to use the recycle?
after loading an image in a ImageView
or when i want change the image of imageview for another image.


4 - this code its correct?

Dim jo = imageview.bitmap As JavaObject
jo.RunMethod("recycle", Null)

i m working on app like a tinder, where i will load pictures every click, I need to avoid as much memory crash.

I really appreciate if someone can explain me.
thank you.

ps: i dont know if recycle its the right function to help me on this case.

thx

In most cases you don't need to use Bitmap.recycle at all. Just make sure that there are no live references to the bitmaps that are no longer used.

Also make sure to use LoadBitmapSample when loading images.

1 imageview will change the image every click.

the user can see around 50+ images on the same imageview.

its correct use the recycle on this case or have another way to avoid crash?

Start without it and see whether you encounter any memory issues. It is more important to avoid loading large images.
