Have you had experience with optimizing user interface performance?

Yes, I have experience optimizing UI performance in Android applications. The main approaches included:

• Using RecyclerView instead of ListView for efficient handling of large lists.
• Layout optimization: reducing View hierarchy depth, using ConstraintLayout.
• Asynchronous data and image loading (e.g., with Glide or Picasso).
• Caching and resource reuse.
• Profiling with Android Profiler to identify bottlenecks.

For example, replacing nested LinearLayouts with ConstraintLayout significantly reduced rendering time and improved interface responsiveness.
