I focus on performance optimization because efficient layouts are essential. To manage large datasets, I use RecyclerView. Asynchronous operations play a vital role, and I take advantage of Kotlin coroutines for lightweight and effective threading. Memory management is also crucial; I implement image caching to minimize memory usage. I consistently avoid memory leaks by avoiding static references, releasing resources properly, and unregistering broadcasts. For UI operations, I prefer using background threads instead of the main thread. For instance, in a recent project, I optimized image loading with Glide and utilized coroutines for network calls, which significantly enhanced performance.
