how to to Load Large Images Efficiently in RecyclerView with Glide on Android
Could someone explain I'm stuck on something that should probably be simple. I've looked through the documentation and I'm still confused about I'm experiencing performance optimization when loading large images in a RecyclerView using Glide. My RecyclerView is set up to display a grid of images fetched from a remote API. While testing, I noticed the scrolling is choppy, especially with images larger than 1MB. I'm using Glide version 4.12.0, and here's the relevant part of my Adapter: ```kotlin class ImageAdapter(private val imageUrls: List<String>) : RecyclerView.Adapter<ImageAdapter.ImageViewHolder>() { override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ImageViewHolder { val view = LayoutInflater.from(parent.context).inflate(R.layout.image_item, parent, false) return ImageViewHolder(view) } override fun onBindViewHolder(holder: ImageViewHolder, position: Int) { Glide.with(holder.itemView) .load(imageUrls[position]) .override(300, 300) // Resizing to fit the screen .into(holder.imageView) } override fun getItemCount(): Int = imageUrls.size class ImageViewHolder(view: View) : RecyclerView.ViewHolder(view) { val imageView: ImageView = view.findViewById(R.id.imageView) } } ``` I've tried using the `.override()` method to resize the images to 300x300 pixels, but it doesn't seem to improve performance significantly. I also set a placeholder and an behavior image to handle loading states. When I profile the app with Android Studio's profiler, I see important memory usage spikes and garbage collection pauses when scrolling. My `RecyclerView` is inside a `CoordinatorLayout`, and I'm concerned that this might be contributing to the performance optimization. I've also checked for potential memory leaks using LeakCanary, and it looks good, but the performance is still not what I expected. I suspect I might be missing some caching strategy or options in Glide. Any suggestions on how to optimize image loading in this scenario? Has anyone else encountered this? I've been using Kotlin for about a year now. The stack includes Kotlin and several other technologies. What's the best practice here?
