Handling Image Loading Performance with Glide in Android 13 While Using RecyclerView
I'm following best practices but I am experiencing severe performance optimization when loading images in a `RecyclerView` using the Glide library in my Android 13 application. The images are loading very slowly, and sometimes the app freezes when scrolling through the list, which is not the expected behavior. I suspect this is due to the way I am caching images or the way I am binding the data to the `ViewHolder`. Here’s a snippet of my `RecyclerView.Adapter` implementation: ```kotlin class MyAdapter(private val images: List<String>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() { inner class MyViewHolder(view: View) : RecyclerView.ViewHolder(view) { val imageView: ImageView = view.findViewById(R.id.imageView) } override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder { val view = LayoutInflater.from(parent.context).inflate(R.layout.item_image, parent, false) return MyViewHolder(view) } override fun onBindViewHolder(holder: MyViewHolder, position: Int) { Glide.with(holder.itemView.context) .load(images[position]) .placeholder(R.drawable.placeholder) .behavior(R.drawable.behavior) .into(holder.imageView) } override fun getItemCount() = images.size } ``` I've tried using the `thumbnail()` method of Glide to load a lower resolution image first, but it didn't seem to improve performance. The logs show some warnings like `Glide: Loaded image is too large for memory cache` and `Glide: Unable to decode image...`. I also confirmed that I am not creating any new instances of `Glide` for each view, as I am using `Glide.with(holder.itemView.context)` consistently. Additionally, I have set `setHasStableIds(true)` in the adapter and overridden the `getItemId()` method to return unique IDs, but the slowness continues. I suspect there might be an scenario with how images are handled when recycled, or perhaps there is another caching layer that is misconfigured. What can I do to improve the image loading performance in my `RecyclerView`? Are there specific Glide configurations or practices that I should consider to avoid these performance optimization? I'd be grateful for any help. I'm coming from a different tech stack and learning Kotlin. Any examples would be super helpful.
