In which scenarios is the lazy loading pattern used?

The lazy loading pattern is used when creating an object or loading data is an expensive operation, and it is worth postponing until it is actually needed. In Android, this is often applied for:

• Deferred loading of images or data from the network to avoid blocking the UI
• Initialization of resources that may not be needed immediately (e.g., databases or heavy view components)
• Performance optimization and memory saving

Example: loading an image into an ImageView only when scrolling to it in a list (RecyclerView). This allows not to load all images at once, but only as needed.
