Android Question Simple question about recycle imageview

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?


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
