One of the challenging tasks in Android development was optimizing the application's performance with large amounts of data in RecyclerView. It was necessary to ensure smooth scrolling and minimal memory consumption when loading images and data from the network. To achieve this, I used the ViewHolder pattern, the Glide library for efficient image loading and caching, and implemented pagination with the Paging Library.

Example of using the Paging Library:

val pager = Pager(PagingConfig(pageSize = 20)) {
    MyPagingSource()
}

val flow = pager.flow.cachedIn(viewModelScope)

This significantly improved UX and reduced the load on the device.
