Best way to make thumbnails for app gallery

Question

I'm working on a simple gallery app. I'm wondering what's the best way to create and dsiplay thumbnails. I was thinking about using ThumbnailUtils, making thumbnail for new pictures and then store it in app data storage as I assume that doing it every time when user displays all images isn't efficient. Though I'm not so sure what's better memory-wise. To load an image into ImageView which is part of RecyclerView item I'm using Glide. I don't know if .thumbnail(...) does what I want so I think I need to create thumbnails myself. Could someone show me the correct way to do this? I want the app to load quickly so it's obvious I can't load full resolution images to recycler.

The best way for your result is to use the GridLayout. I wrote an answer yesterday how to achieve that Widget. Take a look. Cheers!
